At the moment I am using the following code: mysql_query($sql) or header("Location: /error"); To prevent the rest of the script running I need to add exit; or die(). Is there any way to do that using the inline approach as above or do I need to use: $result = mysql_query($sql); if (!result) { header("Location: /error"); exit(); } Thanks php mysql share|improve this question edited Aug 28 '13 at 20:11 hdvianna 337211 asked Nov 8 '10 at 16:04 lethalMango 2,23583773 add a comment| 4 Answers 4 active oldest votes up vote 10 down vote accepted How about: function customDie($location) { header('Location: ' . $location); exit(); } mysql_query($sql) or customDie("/error"); share|improve this answer answered Nov 8 '10 at 16:07 Fosco 27.3k45593 Never thought about doing that, great idea. Thanks! –lethalMango Nov 8 '10 at 16:18 add a comment| up vote 5 down vote If you insist on doing things this way it is better to make a custom query method which handles all this. Something like function custom_mysql_query($query) { $doDebug=true; // Set to true when developing and false when you are deploying for real. $result=mysql_query($query); if(!$result) { if($doDebug) { // We are debugging so show some nice error output echo "Query failed\n
$query\n"; echo mysql_error(); // (Is that not the name) } else { // Might want an error message to the user here. } exit(); } } Then just call custom_mysql_query instead of mysql_query then you will always die if a query fails and if $debug is true, you will also get the query which failed and the database error. But really: You should NEVER use mysql_query or functions which call it(Such as the one I just wrote). It is far too unsafe to ever be used. (Far too difficult to avoid sql injections) Use the pdo classes instead of the mysql_ methods(Google it, there are many tutorials and explanations online). share|improve this a
