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"
  }
}
