Sample code for PHP static variable static demo

In the range of variables in PHP, there is a very important variable ―php static variable statics. In the following article, we will use specific code examples for you to detail the main usage of static variables in PHP, we hope to help you.

Take a look at the following example:

Example of a static variable that requires PHP

<? PHP function Test () {$w 3sky = 0; echo $w 3sky; $w 3sky++;}?>

This function is of little use because the value of $w 3sky is set to 0 and output "0" each time it is called. Adding a variable to a $w 3sky++ has no effect, because once you exit this function, the variable $w 3sky does not exist. To write a count function that does not lose this count value, define the variable $w 3sky as static:

Example using PHP static variable statics

<? PHP function Test () {static $w 3sky = 0; echo $w 3sky; $w 3sky++;}?>

Now, each call to the Test () function outputs the value of $w 3sky and adds one.
