You can do this quite simply with variable function names. Essentially,
create a variable with the name of the method you want to call, and use
that where you would otherwise use the method name in the call: i.e. if
you have the name of a function in $funcname, you would do
$obj->$funcname(). Here's a full example:
<?php
error_reporting(E_ALL);
class foo {
function me_foo() {
echo "Me Foo!\n";
}
function you_foo() {
echo "You Foo!\n";
}
}
$foo = new foo;
$test = 'me';
// The direct way:
$foo->{$test . '_foo'}();
// Slightly less direct but perhaps more readable:
$method = $test . '_foo';
$foo->$method();
$test = 'you';
// The direct way:
$foo->{$test . '_foo'}();
// Slightly less direct but perhaps more readable:
$method = $test . '_foo';
$foo->$method();
?>
Hope this helps,
