'Cannot set time limit' warning

[RK]

I'm getting the following message:

Warning: set_time_limit(): Cannot set time limit in safe mode in /home/..../download.php on line 81

What is the cause / remedy?

Thanks.

Php is running in safe mode. In order to turn it off you have to change following in the php settings file (if you have permissions to modify it):
safe_mode = Off

Unfortunately i cannot help if you have no permissions to modify php.ini file.

The only thing you could do is remove set_time_limit(0); from the download.php. This will set max allowed script execution time to default value set by hosting provider. Usually 30 seconds.

Thanks for the get-back.  I was afraid of that.

Unfortunately, the web site I'm working on is hosted by an ISP who won't let me change PHP parameters.   I'm looking at transferring files that are typically 25-30 MB to clients who usually connect from their homes by cable and DSL.  Dialup is not a significant concern.

Thoughts, anybody?

This is from php manual.
Note that set_time_limit() has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the configuration file.
