array_column(array$input,$column_key,$index_key) 第一个参数为原始数组,第二个参数(多维数组键名)为新数组的值,第三个参数(多维数组键名)为键.结果为一个键值对数组 $array = [['id' = 1,'name' = 'tom','age' = 18],['id' = 2,'name' = 'jack','age' = 1
array_column( array $input , $column_key , $index_key)

];
$arr = array_column($array,'name','id');
echo '<pre class="brush:php;toolbar:false">';
