# PHP Default Arguments

If we call a PHP function without arguments, PHP functions takes the default value as an argument, just like in C++.
Example 1: Code for Default Argument for a function with a single argument.

<!DOCTYPE html> <html> <body>   <?php function weight($defaultweight = 60) { echo "The weight is :$defaultweight <br>"; } weight(45); weight(); weight(70); weight(80); ?>   </body> </html>

Output

The weight is : 45 The weight is : 60 The weight is : 70 The weight is : 80

Example 2: Code for Default Argument for a function with more than one argument.

<!DOCTYPE html> <html> <body>   <?php function hw($weight = 60,$height = 5) { echo "The height and weight is : $height,$weight<br>"; } hw(45,4); hw(); hw(70,6); hw(80,5); ?>   </body> </html>

Output

The height and weight is : 4, 45 The height and weight is : 5, 60 The height and weight is : 6, 70 The height and weight is : 5, 80
