Closed 8 years ago.
I am inserting a huge data values through CSV file via HTML form.
I have used set_time_limit(0); so that script run until the whole operation is not performed.
Fatal error: Maximum execution time of 300 seconds exceeded in
C:\xampp\htdocs\clytics\include\clytics.database.php on line 135
Now, I am trying to catch this fatal error.

I have used set_time_limit(0); so that script run until the whole
operation is not performed.
Probably needs more memory as well. Basically your code is just a hog & you need to tame the way it is gobbling up resources.
But that is just a tangent on the overall architecture issues you might be facing.
Specific to there issue, is there something in your code that would override that value of set_time_limit(0);?
Also, ar you running this script via the command line or the PHP in Apache? Because the CLI config php.ini is 100% different form the Apache module config of php.ini.
For example, on Ubuntu the Apache PHP php.ini is here:
/etc/php5/apache2/php.ini
But the command line (CLI) php.ini is here:
/etc/php5/cli/php.ini
And if you want to brute force your script to eat up memory regardless of your config settings, you can add this to the top of your PHP file:
ini_set('MAX_EXECUTION_TIME', -1);
If one reads up more on set_time_limit this comes up:
Set the number of seconds a script is allowed to run. If this is
reached, the script returns a fatal error. The default limit is 30
seconds or, if it exists, the max_execution_time value defined in the
php.ini.
Then reading up on max_execution_time this comes up:
This sets the maximum time in seconds a script is allowed to run
before it is terminated by the parser. This helps prevent poorly
written scripts from tying up the server. The default setting is 30.
When running PHP from the command line the default setting is 0.
But then, the magic 300 number shows up:
Your web server can have other timeout configurations that may also
interrupt PHP execution. Apache has a Timeout directive and IIS has a
CGI timeout function. Both default to 300 seconds. See your web server
documentation for specific details.
So now you know where the 300 comes from. But doing ini_set('MAX_EXECUTION_TIME', -1); should let you run the script without a timeout.
And final bit of info if none of that somehow works: Look into max_input_time:
This sets the maximum time in seconds a script is allowed to parse
input data, like POST and GET. Timing begins at the moment PHP is
invoked at the server and ends when execution begins.
While max_input_time might not seem to be related, in some versions of PHP, there is a bug where max_input_time and max_execution_time are directly connected.
