I am running an algorithm in PHP which has a lot of data involved. All the processing happens within a nested for loop. Strangely, the outer for loop stops working after 'X' number of iterations (where 'X' is changing all the time I run the script). It takes anywhere between 5 mins to 30mins for the script to crash depending on 'X'. It does not throw out any errors, and only does an incomplete printout of my var_dump (in the first iteration of the outer loop)
These are the precautions I took: 1. I have set the timeout limit in php.ini to be 3600sec (60mins). 2. I am printing out the memory_get_usage() after every outer for loop iteration and i have verified that it is much lesser compared to the max memory allocated to php. 3. I am unsetting arrays once they are used 4. I reuse variable names to limit memory within the forloop 5. I have minimal calls to my DB
I have been solving this for a long time to no avail. So my question is what can be the cause of this problem/how do I go about debugging it. Thank you so much! Extra: If i work with a much smaller test data size, everything works fine.
