PHP allows to call user functions through two different functions shown in the examples below.
A small difference in these 2 examples one has all arguments in an array param the other uses multiple params.
The difference is the function called call_user_func() vs call_user_func_array()
<?php
/* Call User Function with Vars */
function car ($color, $doors) {
if ($doors==4 && $color=="blue")
print "We have no $color 4 door cars, sorry";
else
print "Our $color 5 door cars are only $9999";
}
call_user_func ('car', "blue", 4) . "\n";
call_user_func ('car', "red", 5);
?>
<?php
/* Call User Function with Array */
function debug($var, $val)
echo "***DEBUGGING\nVARIABLE: $var\nVALUE:";
if (is_array($val) || is_object($val) || is_resource($val))
print_r($val);
else
echo "\n$val\n";
echo "***\n";
}
