PHP Function – PHP has already made more than thousand of function.
You can create your own function manualy.
PHP has pre build fuction but you can create your function with logic.
A user-defined function declaration starts with the word function
Now we can create myFunction(), then ({) bracket are indicate the start the function code and (}) indicate close the function code.
After complete the code call the function.
<!DOCTYPE html>
<html>
<head>
<title>User Defined Function</title>
</head>
<body>
<?php
function myFunction() {
echo "Welcome to tutorialfamily";
}
myFunction(); // call the function
?>
</body>
</html>
An argument like is variable.
Pass the argument value to the function.
An argument passed inside the function name as a variable.
All argument value passed after the variable declare.
Below example: we have declare function with argument variable ($cname). Then declare the all argument value inside the function name.
<!DOCTYPE html>
<html>
<head>
<title>PHP Function Arguments</title>
</head>
<body>
<?php
function carName($cname) {
echo "$cname.<br>";
}
carName("Toyota");
carName("Honda");
carName("Verna");
carName("Versa");
carName("Oddi");
?>
</body>
