line 157 is:

$text = preg_replace(sql_regcase("/(drop table|show tables|#|--|\\\\)/"),"",$text);

回答1:

Might be you are using php7 or higher in which sql-regcase is removed

Reference of sql-regcase

回答2:

This function was DEPRECATED in PHP 5.3.0, and REMOVED in PHP 7.0.0 - are you using PHP7 (use php --version to know) If not using PHP7 but an older release, did you enable the mysql extension in your php.ini file?

Note that use of mysql_* function is deprecated as well, so use pdo or mysqli
