Function parameters in PHP are small units of a program which can take some input in the form of parameters and does some processing and may return a value.
You declare a function parameter after the function name, and inside a parenthesis.
You can declare function parameters in PHP in much the same way as you declare a variable.
Let us write a program that multiplies a value by 10 and return the value.
<?php
function multiply($value){
$value = $value * 10;
return $value;
}
$result = multiply(10);
echo "The return value is ".$result;
?>
