@NogDogOct 21.2009 — #memory_get_usage() can tell you how much memory is being used at any given point in the script. Other than that, I don't know of anything that specifically looks at memory usage for a given variable. strlen() for any scalar string variable should give you a good idea, whereas arrays might need some sort of looping and/or recursive function. @NogDogOct 22.2009 — #
It would only show variables in the global scope, so possibly there could be something within a function scope, for example, that would not show up.@NogDogOct 22.2009 — #Yes, when a function returns it should release all local variables. I'm just pointing out possibilities. Could be the same thing with class/object variables (which should be released when the object is destroyed.
Other things to possibly look at are files read into variables then not unset() when done with them (I'm not sure how smart the PHP compiler is about release such variables when they're no longer needed), or query result sets, perhaps.
Showing memory use of all variables or similar?
Hi
I made a script that loops through a textfile and for each line I call a function in an included php-script which I didn’t make. Memory consumption is increasing drastically when I’m running the script. It takes several hours, and I guess it will hit the memory roof after a while and I suppose there’s something in the function I call that are doing this (some variables not freed or something).
Is there a way to see what (variables) are taking what amount of memory? Is it possible to free memory without knowing what’s going on in the “external” function? Btw: there’s actually not much I can do with that function.
Thanks
