任何人都知道适当的正则表达式来获取任何符号（例如。/ _等）。我正在尝试提取所有看起来不像1-3个完整单词的东西。

您可以使用public function userTopRecruitsCurrMonth(){
$tempUID = array();
$mainAssocArr = array();
for ($i=0; $i < User::count(); $i++) {
if($i == 0){
$offset = 0;
}
else{
$offset = $this->take * $i;
}
$users = User::take($this->take)->offset($offset)->get();
foreach ($users as $value) {
$refCnts = User::where('referral', $value->aff_id)->where('signup_date', '>=', 'startDateOfCurrentMonth')->count();
if($refCnts > 0){
$tempUID['userAffID'] = $value->aff_id;
$tempUID['userRecruits'] = $refCnts;
$mainAssocArr[] = $tempUID;
}
}
}//End of For loop
foreach ($mainAssocArr as $key => $row) {
$volume[$key] = $row['userRecruits'];
$edition[$key] = $row['userAffID'];
}
array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $mainAssocArr);
return $mainAssocArr;
}
请参见下面的示例
REGEXP_CONTAINS(line, r'[./_]')要排除所有非单词字符，可以使用#standardSQL
WITH `project.dataset.table` AS (
SELECT 'Online Chat' line UNION ALL
SELECT 'http://mailserver.test.com/zjalLNG391Vkfalka0' UNION ALL
SELECT 'social' UNION ALL
SELECT 'test.com' UNION ALL
SELECT 'poc_email_outbound~51-tester-test~2018-04-12' UNION ALL
SELECT 'http://mailserver.test.com/u/130931jiojf101901'
)
SELECT line
FROM `project.dataset.table`
WHERE REGEXP_CONTAINS(line, r'[./_]')
，它等效于REGEXP_CONTAINS(line, r'\W')
您可以将后者扩展为要从条件中排除的更多字符
