CLI script memory use

Is it possible to run a CLI PHP script with unlimited memory from PHP perspective but restrict how much processor/memory it consume at the system level?

The reason I ask, is because I have a script which needs to spider a massive HTML file (over 130 MB). The spidering program doesn't seem to work when I partition the massive file into smaller chunks and support isn't not responding to my request.

As a last ditch attempt I figure I can maybe set the memory to unlimited in PHP/MySQL but some how control the RAM the processes get and hopefully virtual memory will do the trick.

ulimit -m

Thanks you for that.

So from quickly reading the docs, I should login as a regular user, set the CPU limit with the-m option to limit memory consumption? Do I need to call these or added these in a bash script or can I call them in a one off setting (I don't really need them after I run this spider program)?

Secondly, while the php.ini for CLI is set to unlimited memory use (script was crashing due to memory shortage which setting to -1 fixed) will limiting the system memory cause the same affect or will it just take longer?

thanks Weirdan
