gettype() leaking memory
I'm using the twitter-async library to do some oauth calls to twitter but ultimately, a lot of memory is being used up. I tried running the xdebug execution trace and this is where I feel t开发者_JAVA百科he memory is getting leaked.
json_decode()
is using 47077232 bytes. Okay. This is fine.
But gettype()
? Why should this too be using similar amount of memory?
How could this be prevented?
The script runs in a loop and the memory usage keeps going up. I'm using gc_collect_cycles()
at number of places and it is showing improvement. But this one, I can't understand why should this happen.

From the documentation:
Never use gettype() to test for a certain type, since the returned string may be subject to change in a future version. In addition, it is slow too, as it involves string comparison.
Instead, use the is_* functions.
e.g. use is_array
, is_string
etc.
