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：
PHP;">
// 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: $key)
"; } // "walk" trough each array item and call the function: // "format_array_values" array_walk($array,'format_array_values',$some_var); // print the result: print_r($array); /* The output will be: Array ( [0] => NEW: PHP (KEY: 0)
[1] => NEW: arrays (KEY: 1)
[2] => NEW: are (KEY: 2)
[3] => NEW: cool (KEY: 3)
) */
"; } // "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)
[1] => NEW: arrays (KEY: 1)
[2] => NEW: are (KEY: 2)
[3] => NEW: cool (KEY: 3)
) */
希望本文所述对大家的PHP程序设计有所帮助。
