I’m currently running PHP 5.3.9, Apache 2.2.22, Mandriva 2010.2.

We used to be running on an old as PHP4 machine, i’ve since migrated our server to a new box, and everything is now working (unfortunately with a few legacy settings like register_globals!), except one page.

This one page sends a large POST request sometimes, and when it sends something over x (I’m not sure of the exact number), the PHP script behaves as if it never received any $_POST at all and gives me undefined errors. With a smaller POST it behaves like normal (yay).

Example of POST (grabbed using Opera Dragonfly):

grid[153][1]    256663
grid[153][2]    629969
grid[153][3]    Some Name
grid[153][4]    PSSERVICE
grid[153][5]    PS Service (PSSERVICE)
grid[153][6]    
grid[153][7]    
grid[153][8]    
grid[153][10]   
grid[153][12]   
grid[153][13]   1
grid[153][14]   PAYMENT PENDING
grid[154][0]    2012-03-04
grid[154][1]    256343
grid[154][2]    630133
grid[154][3]    Some Other
grid[154][4]    PSSERVICE
grid[154][5]    PS Service (PSSERVICE)
grid[154][6]    0
grid[154][7]    0
grid[154][8]    0
grid[154][10]   0
grid[154][12]   0
grid[154][13]   0
grid[154][14]   JOB
.... etc,etc,etc.....
total_tech_val  2481.1118181818
total_parts 414.99
total_traveltime    152.44
total_adjustment    0
total_net_val   2481.1118181818

I’ve tried increasing limits within the php.ini file, heres a few examlpes:

post_max_size = 32M
max_execution_time = 60
max_input_time = 60
max_input_vars = 5000
memory_limit = 128M

What could be causing this odd behaviour?

NOTE: There is no error given in output (with E_ALL on, apart from the undefined errors), or inside the error log.

EDIT:
When doing a “var_dump($_REQUEST);”, i am getting the first part of the grid[][] but missing everything else. (gets up to element [76][13] or so). So it appears as if its reaching a limit and being cut off.

I am running the suhosin extension.

    Make sure your php.ini configuration file is not limiting the data being sent.

    Keep a eye on these variables:

    post_max_size = 32M
max_execution_time = 60
max_input_time = 60
max_input_vars = 5000
memory_limit = 128M
suhosin.post.max_vars = 3000
suhosin.post.max_array_index_length = 400
suhosin.post.max_array_depth = 200
suhosin.request.max_array_depth = 200
suhosin.request.max_array_index_length = 400
suhosin.request.max_vars = 3000
