Understanding PHP: Basics and Use Cases
PHP has a few features that help to improve code quality and readability. For example, it has support for comments that can be used to document a section of code. It also supports a variety of operators that can be used to conditionally execute code blocks. These include if, if-else, and the ternary operator.
PHP also supports the switch and match statements. Both are conditional control structures that allow you to compare a value against a set of patterns and then execute code blocks based on the results of those comparisons. The difference between the two is that match allows you to specify multiple patterns that can be matched against a value, while switch supports only one pattern. The use of match is recommended, as it provides a more expressive syntax and advanced type checking capabilities than switch.
Another key feature is its versatility in terms of capturing and using data from other applications or websites. For example, if you want to greet visitors on your website with their full names, you can capture their first name from a web form and print it on a separate part of the page.
Its flexibility is further boosted by its ability to run as soon as it's written, without the need for compiling – thus saving time and effort. Additionally, it is well-optimised and therefore tends to run smoothly across a wide range of different machines. All these features make it a highly useful tool for developers who need to produce responsive and user-friendly websites.
Rasmus Lerdorf launched PHP in 1994 and it quickly gained prominence for back-end website development. It is a general-purpose programming language and supports multiple databases including MySQL. It also works with CMS like WordPress and is easy to use. It is case sensitive for variables and uses semicolon and double slash to separate statements.
PHP is more popular for back end development and works well with CMS systems like WordPress or Moodle. It’s also ideal for e-commerce websites and web applications that require database connectivity.
PHP is a well-established server-side scripting language that still holds a dominant market share. It’s a good choice for database interaction, content delivery, and back end processing. It can also be used in conjunction with front end development through template systems like Laravel Blade or WordPress.
