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 5,64621218 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 Checking the documentation shows that its returns false on an error. So use the return status rather than or die(). It will return false if it fails, which you can log (or whatever you want to do) and then continue. $rv = mysql_query("INSERT INTO redirects SET ua_string = '$ua_string'"); if ( $rv === false ){ //handle the error here } //page continues loading share|improve this answer edited Nov 13 '11 at 14:27 Josh 8,41774489 answered Dec 16 '09 at 23:53 Yacoby 37.6k890111 That Doesn't throw an error? –Byron Whitlock Dec 16 '09 at 23:56 1 I don't think mysql_query throws an exception. –Yacoby Dec 17 '09 at 0:01 8 Indeed, neither mysql_query nor m
