arrays - something similar to sql left join in php -

-

i want sql left join functionality in php.

$table1 = array(     0 => array("id" => "id1", "common_key" => 1),     1 => array("id" => "id2", "common_key" => 2),     2 => array("id" => "id3", "common_key" => 1) );  $table2 = array(     0 => array("name" => "name1", "common_key" => 1),     1 => array("name" => "name2", "common_key" => 2) );  $result = left_join($table1, $table2);

$result should equal array below.

array(     0 => array("id" => "id1", "common_key" => 1, "name" => "name1"),     1 => array("id" => "id2", "common_key" => 2, "name" => "name2"),     2 => array("id" => "id3", "common_key" => 1, "name" => "name1") )

what should left_join function?

$table1 = array(     0 => array("id" => "id1", "common_key" => 1),     1 => array("id" => "id2", "common_key" => 2),     2 => array("id" => "id3", "common_key" => 1) );  $table2 = array(     0 => array("name" => "name1", "common_key" => 1),     1 => array("name" => "name2", "common_key" => 2) );  $result = left_join($table1, $table2); var_dump($result);  function left_join($table1, $table2) {     array_walk(         $table1,         function(&$entry, $key, $jointable) {             foreach($jointable $joinkey => $joinvalue) {                 if ($joinvalue["common_key"] == $entry["common_key"]) {                     $entry = array_merge($entry, $joinvalue);                     break;                 }             }         },         $table2     );     return $table1; }
