So how much should the interview take? In addition to that, the recruitment task the earlier stage of the process takes about hours to complete. Now, that we know what kind of people we want to hire and how to talk to them, we should think of ways to find them. The best way to start the search is by publishing and promoting our job offers. They work especially well when there are many candidates on the market or when you want to find juniors.
The two approaches divide the common methods of searching for PHP developers into two groups — inbound and outbound. Inbound methods refer to all actions that make it possible for your candidates to find your offers themselves. To that end, you can use the following. The easiest way to extend your reach beyond your own website. You can use them as extra places to publish your offers of developer jobs.

Both individuals from outside of your organization and your current employees can be encouraged to actively search their own social circles for suitable prospects, should they be rewarded for it through employee referral program.
When done well, this can be a great source of strong candidates. Organizing educational webinars may not be suitable for direct recruitment, but they allow you to promote your brand and establish a relationship with the developer community.
Such an internship can eventually turn into a full-time job. On the downside, this approach takes a fair amount of time. Also, you need some seniors your interns will learn from to begin with. Outdoor ads such as large billboards or bus advertising may be highly effective. By creating the kind of content your potential candidates need — e.
Do these methods actually work? Well, The Software House was able to quadruple the number of organic free visits we receive monthly from Google in less than a year of regular content marketing efforts.
Content marketing takes time. You can supplement it with PPC-based traffic. However, you should know that the PPC i. Finding a way to acquire organic traffic is most likely the best long-term solution. You can learn more about it from one of our previous articles on how to acquire and retain developers. When we do outbound outreach, we initiate the conversation with our prospects.
Here are some of the most popular inbound methods when it comes to recruiting PHP developers. Q: Explain the use and purpose of the global keyword in PHP. Provide an example of a case where its use would be appropriate, as well as one where it would not be. While there may be cases where this would be justified e. But as is true with most things in coding, never say never.
There are, in fact, a number of robust and stable products out there written in PHP that make heavy use of globals. Similarly, there may be situations where the use of globals in your code is appropriate, but their use should always be approach with caution. Prior to PHP 5. Without namespacing, we might feel compelled to provide a verbose name for our class such as the following:.
Namespacing helps alleviate this issue by enabling the developer to explicitly specify the namespace within which all named items classes, variables, etc. With namespacing, the above verbose class name could be replaced with:. Relative namespace references are supported as well. In addition, named items in other namespaces can be imported in other files and can then be referenced directly.
This is done via the use operator as follows:. Q: What are traits? Describe their major characteristics and why they are useful. Give an example of a trait declaration and a class that uses multiple traits. Traits are an excellent addition to PHP 5. Additionally, you can make use of multiple Traits in a single class. This makes them a powerful aid in the organization and separation of concerns in the codebase and, as such, helps to honor the composition over inheritance design principle.
The use keyword is once again employed, this time for importing from another namespace to include one or more traits in a class definition. Committing to memory what can easily be found in a language specification or API document is no indicator of proficiency. But that said, someone who is intimately familiar with a programming language will have its syntactical and functional details and nuances at his or her fingertips.
When, how, and why and perhaps why not should each be used? Through their use we can define how a class should react when an undefined, protected, or private method is called.
This means that if we have this method defined we can use the ClassName::notVisibleMethod syntax; e. In the above set of examples, we have encapsulated the whiskers implementation from the outside world and made it the only available object exposed in this way.
The clients of such properties and methods do not need to know anything about the underlying whiskersService or how the Dogs class is storing its data at all. Collectively, these methods increase our ability to flexibly compose objects. The opportunity for object abstraction and encapsulation, and thus reusable, more compact code and ultimately a more manageable system as a result are also increased.
Care should be taken, though, in using these convenient methods, as the benefits can come at a cost. They are slower than straight access to an otherwise public property in question, and also slower than defined getters and setters. They also hamper use of certain useful capabilities such as object reflection , autocomplete in your IDE, automatic documentation utilities like PHPDocumentor, and so on.
So if these are facilities you want or need to rely on, you may consider defining methods and properties explicitly instead. The pros and cons should be evaluated on a case-by-case basis.
Give usage examples. Most of PHP development deals with getting and processing data from one source or another, such as a local database, local files, a remote API, etc. As such, developers spend a great deal of time getting, organizing, moving, and manipulating that data. The net effect of such an active development community is that the distribution of developers working with a particular framework starts to shrink, and could make it harder for you to find that specific skill.
If the candidate has a solid background here, the chances of success for that candidate working into and adding value to your application are greater, regardless of the specific frameworks being used in your environment. Many provide highly similar functionality to one another, but the slight variations make each one more perfectly suited to a particular use.
PHP supports automatic type conversion based on the context in which a variable or value is being used. If you perform an arithmetic operation on an expression that contains a string, that string will be interpreted as the appropriate numeric type for the purposes of evaluating the expression.
So, if the string begins with one or more numeric characters, the remainder of the string if any will be ignored and the numeric value is interpreted as the appropriate numeric type. On the other hand, if the string begins with a non-numeric character, then it will evaluate to zero. Depending on who you ask, automatic type conversion is either a great feature or one of the worst pitfalls of the PHP language.
On the one hand, when used consciously and properly, it can be very convenient for the developer e. On the other hand, it can easily lead to headfakes and hard-to-track-down bugs when it is employed inadvertently, since no error message or warning will be generated.
Q: Explain the significance of using the static keyword when invoking a method or property, including how it differs from the self keyword? When would you use it and why? Provide an example.
As of PHP 5. The makeSounds method in the Dog class first invokes self::makeSound. Next, the makeSounds method in the Dog class invokes static::makeSound. Such a candidate will understand not only how to do something, but the various options available, and the performance and functional ramifications of each.
Central to much of PHP development is the array. These are good for most uses where an iterable data structure is needed. Internally in PHP, arrays are stored, like many other data structures, as hash tables. PHP is written in C where there is no such thing as an associative array: arrays in C can only have integer indices. Therefore, a hash function is used to translate PHP array indices both integer and string into appropriate numeric indices and the array values are stored at that location or bucket in the hash table.
The process of finding bucket entries based on a hash of the array keys is of O 1 complexity using Big O notation. This because no iteration over the hash is needed, since the hash function produces the exact location in the table. Note that this changes slightly if there is more than one element in the bucket. Specifically, when an element is added to an array, if addition of the element would cause the array to exceed its currently allocated size, PHP responds by doubling the memory allocation.
For instance, in some cases, it could be expected that PHP developers would also have coding abilities in client-side development like Javascript or CSS. By having a knowledge of programming languages and web solutions, PHP developers can help to create a good customer experience for clients who use your application or website. In addition to hard skills like experience with PHP coding, there are soft skill sets that can help when considering hiring PHP developers.
For instance, web developers who have clear and concise communication with the development team, good business and marketing sense, quick problem-solving skills, leadership qualities, and a knowledge of the project requirements are all important things to consider when looking to hire PHP web developers.
With all of these skills, you can be sure that you will find a dedicated PHP developer for your web development projects and that you will be satisfied with their contribution to your business or startup. One of the first things to recognize when talking about the average salary of PHP developers is that there are many different factors that can make it difficult to accurately predict how much PHP developers would be paid.
For instance, there is a difference in the country where the web developer is working from, whether they are a freelancer or an in-house PHP developer, the skill and experience level of the web developer, and the difficulty of the job or project that they are doing. However, there are still ways of getting an average salary for PHP web development services through looking at averages on sites like ZipRecruiter. However, this number would vary between full-stack developers and junior developers and the country where web development is happening.
When compared to salaries of other programming languages, PHP is known for having a lower average salary for a few different reasons. Firstly, because PHP is so easy to use and quick to learn, there are many junior and beginner PHP developers out there.
However, with more experience and a higher level of coding abilities, then the salary for PHP can increase significantly. Furthermore, despite the lower salary, there is a lot of demand for PHP web apps and sites which means that there are opportunities for finding well-paying jobs and quality PHP developers. Now that we have outlined the skills, duties, and average salary of PHP developers, the next step is to figure out what kind of web developer you are looking for for your project.
For instance, one aspect to figure out is whether you are looking to hire an in-house PHP developer or a freelance PHP developer. In-house PHP developers would likely be someone that you want to bring into your company as a long-term hire and be a permanent part of your PHP development team. The pricing model for hiring an in-house PHP developer is often higher because of the costs for insurance, workspace, training, etc.
Often, freelance PHP developers are a better way to go for small businesses or startups that are still growing their companies. Freelancers are also a good choice if you only need a developer for one project or quick we services.
Freelancers may not be as invested in the long-term development of your company or be the best experts in their field, but they can help to develop a specific project, application, or website. So the next question is, where can you find dedicated PHP developers?
