PHP 数组模糊查询

 function search() {
 $a=array(
 '0' => array('id'=>1,'pid'=>0,'name'=>'水果'),
 '1' => array('id'=>2,'pid'=>0,'name'=>'蔬菜'),
 '2' => array('id'=>3,'pid'=>1,'name'=>'食品'),
 '3' => array('id'=>4,'pid'=>2,'name'=>'运动'),
 '4' => array('id'=>5,'pid'=>1,'name'=>'电脑'),
 '5' => array('id'=>6,'pid'=>'香果','name'=>'香蕉'),
 '6' => array('id'=>7,'pid'=>4,'name'=>'牛奶'),
 '7' => array('id'=>8,'pid'=>5,'name'=>'西瓜'),
 '8' => array('id'=>9,'pid'=>7,'name'=>'苹果'),
 );
 $arr=$result=array();
 foreach ($a as $key => $value) {

 foreach ($value as $valu) {
 if(strstr($valu, '果') !== false)
 {
 array_push($arr, $key);
 }
 }
 }
 foreach ($arr as $key => $value) {
 if(array_key_exists($value,$a)){
 array_push($result, $a[$value]);
 }
 }
 return $result;
 }
 var_dump( search());

结果:

 array(3) {
   [0] => array(3) {
     ["id"] => int(1)
     ["pid"] => int(0)
     ["name"] => string(6) "水果"
   }
   [1] => array(3) {
     ["id"] => int(6)
     ["pid"] => string(6) "香果"
     ["name"] => string(6) "香蕉"
   }
   [2] => array(3) {
     ["id"] => int(9)
     ["pid"] => int(7)
     ["name"] => string(6) "苹果"
   }
 }
