Need more PHP memory

I am trying to run a PHP script, but it does not work. I checked the error log and found this pertinent line:

Allowed memory size of 16777216 bytes exhausted (tried to allocate 3061262 bytes)

How can I increase the limit for this site?

Thanks!

 

Increase the value within your php.ini file for Apache2 by modifying the line into:

memory_limit = 64M
