数组比对问题

本帖最后由 u012984377 于 2014-08-08 11:21:42 编辑
实现string '越野,城市SUB' (length=16)
与数组里的'wjc_title' => string '2厢小轿车' (length=13)比对,看是否有满足条件的,

怎么搞,刚学习PHP不久
------解决方案--------------------
不要贴图,贴出你的数组。
说明一下满足条件是指什么? 
------解决方案--------------------
$ar1 = array('a1', 'a2');<br />$ar2 = array(<br />  array('wjc_id' =>'12', 'wjc_title' =>'a1'),<br />  array('wjc_id' =>'23', 'wjc_title' =>'sfdsds'),<br />);<br /> <br />function foo($item){<br />  global $value;<br />  return $value == $item['wjc_title'];<br />}<br />foreach($ar1 as $value){<br />  echo $value, ' ', array_filter($ar2, 'foo') ? '在' : '不在', PHP_EOL;<br />}
a1 在
a2 不在
