导读：$array = array( array( ‘ id ‘ = ‘ 3 ‘ , ‘ name ‘ = ‘ tom ‘ ),array( ‘ id ‘ = ‘ 5 ‘ , ‘ name ‘ = ‘ jerry ‘ ),array( ‘ id ‘ = ‘ 24 ‘ , ‘ name ‘ = ‘ spike ‘ )); $newArray1 = array_column($array,NULL, ‘ id ‘ );var_dum

$array = array(
    array(‘id‘=>‘3‘,‘name‘=>‘tom‘),array(‘id‘=>‘5‘,‘name‘=>‘jerry‘),array(‘id‘=>‘24‘,‘name‘=>‘spike‘)
);
 
$newArray1 = array_column($array,NULL,‘id‘);
var_dump($newArray1);
//结果
array(
    ‘3‘=>array(‘id‘=>‘3‘,‘5‘=>array(‘id‘=>‘5‘,‘24‘=>array(‘id‘=>‘24‘,‘name‘=>‘spike‘)
)
 
$newArray2 = array_column($array,‘name‘);
var_dump($newArray2);
//结果
array(
    ‘tom‘=>array(‘id‘=>‘3‘,‘jerry‘=>array(‘id‘=>‘5‘,‘spike‘=>array(‘id‘=>‘24‘,‘name‘=>‘spike‘)
)
