PHP apc_store then apc_delete then apc_store returns a failure
I'm new to php and using APC framework. I'm trying to write some unit tests for a class that uses APC, but I'm running in to some problems trying to delete and then set some key values again in APC. My problem can be boiled down to a small set of code not working the way I would expect:
$success = apc_store("helloWorld", 2, 0); // true $success1 = apc_delete("helloWorld"); // true $success2 = apc_store("helloWorld", 3, 0); // false
In addition doing a fetch call on "helloWorld" will return NULL, and I get the warning:
[apc-warning] Potential cache slam averted for key 'helloWorld'
In addition I have tried to add this to my php.ini file:
I have also tried to increase the memory limit from the default 32M to 64M by adding this to my php.ini file:
apc.shm_size = 64M
I found this related question on in Why would apc_store() return false?, but neither suggestion worked me me though.
How can I fix this so that the expected three trues are returned? Why are they not being returned?
Your example code works perfectly for me (true/true/true) in PHP 5.3.12 with apc 3.1.9, so maybe you should try a later version?
