php怎么让错误语句不报错
php让错误语句不报错的设置方法:首先在语句前加上“@”符号,其语法是“@mysql_query($sql, $handle);”;然后用“error_reporting”调节报错等级即可。
php怎么让错误语句不报错?
问题:
比如某条sql插入语句如果异常,就让他略过这句继续执行下面的,而不是抛个异常中断运行。像python的try一样
方法:
如果你用PDO,可以try...catch
try { $pdo->exec($sql); } catch (PDOException $ex) { echo $ex->getMessage(); }
如果你用的mysql或者mysqli函数,可以在语句前加上@符号,比如
@mysql_query($sql, $handle);
这样可以关闭单行语句的错误输出
如果只是警告的话,可以用error_reporting调节报错等级
