Shielding php errors
Method 1: @
Add the @ symbol before any error statement to block errors. For example:
<?php $u_name= @$_POST['u_name']; $u_pwd= @$_POST['u_pwd']; 方法二:error_reporting
Add in the first line of the PHP file: error_reporting(0); that is Maskable errors, for example:
<?php error_reporting(0);
Method 3: display_errors masking method
This method should be the most thorough solution, because the first two methods can only act on a single row or a single file, this applies to all php files. Open the php.ini file and search for display_errors = on. The default should be on, which means the error reporting function is enabled. Just change it to off.
