unable to override php's default exception Messages

[ajoo]

Hi all !

 

I have been using this snippet below to study exceptions:

<?php

mysqli_report(MYSQLI_REPORT_STRICT);

try {
     $connection = new mysqli('localhos', 'root', '', 'test') ;
} catch (Exception $e ) {
     echo "Server Error";
}

?>

If, as in the snippet, I misspell the localhost, I am unable to override the php's own message. If, on the other hand I just misspell say the database name with the host spelt correctly, it overrides the php's default message. ( Default messages in both examples above being different).

 

with the host name misspelt I receive the following warning:

 

 

Warning: mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed: This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server. in D:\xampp\htdocs\xampp\miscellaneous\exceptions.php on line 6

 

With the host name correct but a wrong database name I get the message defined in the snippet. Namely "Server Error".

 

Kindly help resolve this. 

 

Thanks very much.

It appears throws an Exception and a PHP Warning if the hostname cannot be resolved.

Yes, correct. So how to suppress the php Warning ? I do not wish to use the @ operator for this. Is there any other way ? Thanks

Disable all error reporting either with htaccess, php.ini or at the top per php script.

 

htaccess

php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0

php.ini

error_reporting = off

php scripts, last line helps remove strict errors

error_reporting(E_ALL);
ini_set("display_errors", 1);
ini_set('error_reporting', 30711);

Make sure you're still logging those errors, though! You may not want the error message to appear on your site but you certainly should be aware of any problems.
