PHP正则表达式匹配自定义开头结尾之前字符串

话不多说，直接上代码

$arr = 'errorType=curlerror error_message=cURL error 7: couldn\'t connect to host Array ( [Host] => s109.360.qkzj.game-as.com ';
$pattern = '/(errorType)(.*)(?)(Array)/';     //errorType Array为开头 结尾字符串
preg_match_all($pattern, $arr, $matches);
var_dump($matches);

$matches[0][0];                       //带有开头和结尾
$matches[1][0];                       //开头
$matches[2][0];                       //去除开头和结尾
$matches[3][0];                       //结尾
