Note Submitter: joshuajoe REMOVETHIS [at] gmail ---- I'm sure others that don't hold Computer Science degrees have wondered what the whole "recursive" function thing is and why its useful. I won't go into great detail, but imagine if you are storing information and want to tell how to format the values with some sort of extensible templating system. NOTE: This will open up your system to all kinds of attacks, use at your own risk! <?php $dump = "test "; // original string function doThis($i) { // function that we will call recursively echo $i+123; } $function = "doThis"; // which function to call // sample data $data[] = 1; $data[] = 34; $data[] = 30; // imagine this being called in a template function foreach ($data as $value) { // loop through data ob_start(); eval($function."('".$value."');"); // recreate "function" $dump .= ob_get_contents()."\n"; // catch output ob_end_clean(); } echo $dump; /* Outputs: test 124 157 153 */ ?>
