字符串参数拆解到变量 PHP

$paramArr = array('id=1', 'name=jack', 'remark=hahaha', 'username=admin', 'ip=8.8.8.8');

$id=null; $name=null; $remark=null; $username=null; $ip=null;

$output = array();

foreach ($paramArr as $v)
{
	$t = explode('=',$v);
	if($t[0] == 'id' and $t[1] !== 'null') {$id = $t[1];}
	if($t[0] == 'name' and $t[1] !== 'null') {$name = $t[1];}
	if($t[0] == 'remark' and $t[1] !== 'null') {$remark = $t[1];}
	if($t[0] == 'username' and $t[1] !== 'null') {$username = $t[1];}
	if($t[0] == 'ip' and $t[1] !== 'null') {$ip = $t[1];}
}

echo '【id】'.$id.'【name】'.$name.'【remark】'.$remark.'【username】'.$uname.'【ip】'.$ip;

方法有点笨，有更好的办法吗？
