PHP | Recursion
PHP also supports recursive function call like C/C++. In such a case, a function calls itself within the function.
Note: Recursion must be incorporated carefully since it can lead to an infinite loop if no condition is met that will terminate the function.
<?php
function display($num) {
if($num<=5){
echo $num.”,”;
display($num+1); //function call itself.
}
}
display(1);
?>
//Output will be 1, 2, 3, 4, 5
