parameters with default values
It’s known that declaring a php function has the following syntax:
<?php
function function_name(Parameters_list) {
// function
// code
// block
}
?>
an example of this can be like this:
<?php
function nameAndAge($name,$age){
echo "Welcome $name, you are $age years old!";
}
?>
When I issue the following statement:
<?php
nameAndAge("bingorabbit",20);
?>
I will get:
Welcome bingorabbit, you are 20 years old!
Most of us know that, and also we know that to set a default value for any parameter, we can do the following:
<?php
function function_name($parameter1 = "default value", rest_of_the_parameter_list) {
// function
// code
// block
}
?>
which might take the following form:
<?php
function nameAndAge($name="bingorabbit",$age){
echo "Welcome $name, you are $age years old!";
}
?>
so when I issue:
<?php nameAndAge(); ?>
I will get:
Welcome bingorabbit, you are years old!
and when I issue:
<?php
nameAndAge("Ahmed", 15);
?>
I will get:
Welcome Ahmed, you are 15 years old!
The problems is such declaration is that, you can’t just issue:
