gzputs - PHP code example

How to Use the PHP Function Gzputs

PHP is a server-side programming language that allows you to write and code your own functions. Functions are blocks of code that you can use repeatedly throughout your script. These can perform a set of tasks, like resetting a variable or returning data. You can also pass input to the function through arguments, which are a list of values that the function will accept. You can add as many arguments as you want, separated by a comma.

Depending on the value of an argument, it can be passed by reference or by value. In PHP, the list of arguments is evaluated from left to right before the function is called (eager evaluation). You can also pass multiple variables by reference, or skip passing a default argument value. As of PHP 8.0.0, you can even have a trailing comma in the list of argument values.

The gzputs function reads, compresses and writhes the input in small chunks before sending it to the browser. This makes it much faster and can prevent memory problems in larger websites. It is recommended that you use this function if you’re working with large files. In addition, this will make your page load faster.
