PHP 怎么从数组中取值
array(3) {
[0] => array(3) {
["id"] => string(1) "1"
["typename"] => string(7) "分类1"
}
[1] => array(3) {
["id"] => string(1) "3"
["typename"] => string(7) "分类2"
}
我要获取“分类1”的ID值怎么获取？

//你可以用下面的方式试下，我这边考虑到的是遍历哈，假设上面的数组名字为$cate_arr
foreach($cate_arr as $v){
$values = array_values($v);
if(in_array("分类1", $values)) {
$id = $v["id"]; //这样就可以得到分类1的ID值了
break;
}
}

$test=atrray{
array{["id"] => string(1) "1",["typename"] => string(7) "分类1"}
array{["id"] => string(1) "3",["typename"] => string(7) "分类2"}
}
这样写我会取值；得到分类1的值：$test[0][typename];

$arr=array(
'0'=>array('id'=>'1','typename'=>'分类1'),
'1'=>array('id'=>'2','typename'=>'分类2'),
);
foreach ($arr as $k1 => $v1) {
foreach ($v1 as $k2 => $v3) {
if($v3=='分类1'){
echo $v1['id'];
}
}
}

$a=array(3) {
[0] => array(3) {
["id"] => string(1) "1"
["typename"] => string(7) "分类1"
}
[1] => array(3) {
["id"] => string(1) "3"
["typename"] => string(7) "分类2"
}
echo $a[0]['id'];
