查找数组某个指定键值,必须用遍历吗?
数组格式如下:
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ -->Array ( [0] => Array ( [0] => ID [1] => Nickname ) [1] => Array ( [0] => 29 [1] => Test1 ) [2] => Array ( [0] => 654 [1] => Xxx1 ) )
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ -->foreach($array as $value){ if($value[0]==29) { //判断条件成立,进行相关操作 } }
$array = array(0 => array('id', 'name'), array('29', 'test'), array('65', '29')); array_walk($array, $theValue = 'checkvalue', 29); if ($theValue == true) { echo 'ok'; } function checkvalue($value, $key, $number) { if ($value[0] == $number) { //something return true; } } <div class="clear"> </div>
