本文实例讲述了php里array_work用法。分享给大家供大家参考。具体如下：

// the test array $array = array( 'php', 'arrays', 'are', 'cool' ); // some variable for testing: $some_var = 'NEW'; // the function that get's called for each entry function format_array_values(&$item, $key, $some_var) { $item = $some_var . ": $item (KEY: $key)<br/>"; } // "walk" trough each array item and call the function: // "format_array_values" array_walk($array, 'format_array_values', $some_var); // print the result: print_r($array); /* The output will be: Array ( [0] => NEW: php (KEY: 0)<br/> [1] => NEW: arrays (KEY: 1)<br/> [2] => NEW: are (KEY: 2)<br/> [3] => NEW: cool (KEY: 3)<br/> ) */

希望本文所述对大家的php程序设计有所帮助。
