This function allows you to create an alias for a function. For example if you do not like the function name 'substr', create your own alias named 'mid' (perhaps you know this function name from BASIC). It does not work with function which use references.

<?php

                            
 function func_alias($original_func_name, $alias_name)

                            {

                                eval('

                            

                                    function '.$alias_name.'()

                                    {

                                        $args = func_get_args();

                                        $eval_string = "$return = '.$original_func_name.'(";

                                        $i = 0;

                                        foreach ($args as $k=>$v) {

                                            $i++;

                                            $eval_string .= "&$args[$k]";

                                            if ($i < count($args)) {

                                                $eval_string .= ", ";

                                            }

                                        }

                                        $eval_string .= ");";

                                        eval($eval_string);

                                        return $return;

                                    }

                                ');

                            

                                return true;

                            }

                            
 ?>

Usage Example

<?php

                            func_alias('substr', 'mid');

                            echo mid('test', 1, 2);
 ?>
