PHP, an open-source scripting language, helps developers create web pages and applications. Rasmus Lerdorf created PHP in 1994 to track pageviews for his online resume. Since then, coders have continued developing the language: According to GitHub's PopularitY of Programming Language (PYLP) index, PHP is the sixth most commonly used coding language as of August 2023.
This guide explores PHP, including when to use it and which resources can help you master this language.
What Is PHP in Coding?
PHP programming has multiple functions: it can collect data, access server files, and integrate with other coding languages. Developers often use this server-side language because of its array of uses and existing documentation. We explore several of these usages below:
- Webpage Development: PHP language's most common usage is for developing user-friendly web pages that interact with databases. The code works well with HTML, another webpage language.
- Two-Step Authentication: Two-step authentication helps make digital logins more secure. These systems typically send a text message code or require randomly generating security codes through authentication apps. PHP programs can create second-layer authentication systems by generating, sending, and validating private codes.
- Customer Relation Management Software: Customer relation management (CRM) systems are vital to corporations, as they help organize customer data to optimize sales and find new customers. Multiple existing CRM systems use PHP because of the programming language's versatility.

Why Use PHP When Programming?
PHP computer programming allows developers to create visually appealing websites with multilayered design. Prospective web developers should consider learning PHP because of its compatibility with various operating systems and databases.
Developers and graduates of computer science bachelor's programs that already understand several coding languages may find PHP easy to learn. PHP users can save time and money by using free PHP code libraries.
Pros and Cons of Using PHP
Pros
-
Large libraries of open-source cod -
Versatile uses for design and functionality -
Similarities to other popular languages like C++ and Java
Cons
-
Lack of security means anybody can view a company's PHP code and potential bugs -
Poor debugging tools can lead to difficult or subpar maintenance -
Does not use intuitive, human language-style syntax like other coding languages
Companies That Use PHP
According to W3Techs, a website which tracks programming language usage across the web, over 77% of sites worldwide use PHP. Even large companies, like those listed below, use PHP:
- Wikipedia
- Tumblr
- Slack
- Etsy
PHP vs. Python and Java
Like PHP, Python and Java are among the most popular open-source coding languages, according to GitHub's PYLP index. Though they share similarities, each language has its own uses. We contrast these three coding languages in the table below.
| Qualities | PHP | Python | Java |
|---|---|---|---|
| Skill Level | Easy to learn | Easy to learn | Easy to learn |
| Syntax | Traditional coding syntax | Similar to human languages | Traditional coding syntax |
| Focus | Web development | General-purpose language | General-purpose language |
| Speed | Extremely fast | Slower than PHP | Fast |
| Debugging | Slow | Standard | Standard |
Where Can You Learn PHP?
Ambitious coders can learn PHP, a relatively simple programming language, in 3-6 months. Though colleges and universities may offer classes or certificates in PHP, the language is not typically included in the main curriculum of programming bachelor's degrees, meaning learners must pursue PHP as an elective if available.
Beyond classroom settings, students can learn PHP from coding bootcamps and self-education online resources. Coding bootcamps have specialized courses that teach skills like web development and PHP. Enrollees spend a few months learning essential skills and languages from technology specialists.
Self-motivated students can study PHP with the vast array of online resources dedicated to the language. Because PHP is open-source and several decades old, there are many free tools and training modules available.
Prospective students should consider cost, time constraints, and the ability to connect with teachers when choosing an appropriate learning method.
