试试这段代码，希望它能运作

<?php
static $cnt = 0;
$name = 'victor';
$coll = array(
    'dep1' => array(
        'fy' => array('john', 'johnny', 'victor'),
        'sy' => array('david', 'arthur'),
        'ty' => array('sam', 'joe', 'victor')
    ),
    'dep2' => array(
        'fy' => array('natalie', 'linda', 'molly'),
        'sy' => array('katie', 'helen', 'sam', 'ravi', 'vipul'),
        'ty' => array('sharon', 'julia', 'maddy')
    )
);

function recursive_search(&$v, $k, $search_query){
    global $cnt;
    if($v == $search_query){
        ++$cnt;
    }
}
array_walk_recursive($coll, 'recursive_search' , $name);
if ($cnt == 0)
    echo "$name was Not Found";
else
    echo "$name was found $cnt times.";
