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 mysql error handle 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 s

I am curious of the fastest and safest way to (catch an error) and continue if the system is not able to do the insert into MySQL. Should I use try/catch or die or something else. I want to make sure the insert happens but if for some reason it can't I want the page to continue to load anyway. ... $db = mysql_select_db('mobile', $conn); mysql_query("INSERT INTO redirects SET ua_string = '$ua_string'") or die('Error #10'); mysql_close($conn); ... php mysql performance error-handling share|improve this question asked Dec 16 '09 at 23:51 meme 5,63621218 On the use of "or die": phpfreaks.com/blog/or-die-must-die –outis Dec 17 '09 at 0:55 1 As for exceptions vs checking return values, it depends on how many points might generate errors. With one or two points, I'd go with error checking, as it's more performant and just as readable in this case. Once you hit three or more error checks in a code block, exceptions become more readable. It's all about reducing cyclomatic complexity. Note that this covers the point you handle the error; if you're talking about signaling errors, you'll wind up with different guidelines. –outis Dec 17 '09 at 0:59 add a comment| 8 Answers 8 active oldest votes up vote 23 down vote Ch
