$a = array(    array("id"=>7, "title"=>"a"),    array("id"=>5, "title"=>"z"),); $b = array(    array("id"=>5, "title"=>"a"),    array("id"=>1, "title"=>"z"),    array("id"=>2, "title"=>"z"),); foreach($b as $k=>$v)  foreach($a as $t) if($v['id'] == $t['id']) unset($b[$k]);print_r($b);

Array(    [1] => Array        (            [id] => 1            [title] => z        )    [2] => Array        (            [id] => 2            [title] => z        ))

$a = array(    array("id"=>7, "title"=>"a"),    array("id"=>5, "title"=>"z"),); $b = array(    array("id"=>5, "title"=>"a"),    array("id"=>1, "title"=>"z"),    array("id"=>2, "title"=>"z"),); foreach($b as $k=>$v)  foreach($a as $t) if($v['id'] == $t['id']) unset($b[$k]);print_r($b);

Array(    [1] => Array        (            [id] => 1            [title] => z        )    [2] => Array        (            [id] => 2            [title] => z        ))

When an item is removed from a loop, will the next loop be unaffected?

Foreach is not affected
For affected
