HTML & PHP input[] <- array ? Limitations

It's more of a wether can someone confirm my theory, as for going short ways, when you add another input which shall have similar name ex. myvar_0, myvar_1 you are supposed to use javascript to generate tho开发者_如何学编程se inputs, but there is input "array" type, where you crate an input with name myvar[], myvar[], myvar[] and this acts as an array and passes values via post to PHP as an array, but recently i've discovered that for some weird reason this array has limitation of 197 values ( or 196 is the maximum capable index value ) as on chrome for now ( didn't text it on other browser ).

So does anyone else encoutered a similar problem ?

If you're using suhosin, that brings a limit to the max_vars sent via POST.
Default is set to 200, so could be your problem.

See: suhosin.post.max_vars

array format got nothing to do with html or browser , for browser square brackets doesn't mean any special thing it will send all the key , value pairs with same key as opt[] e.x

for

<input type="hidden name="opt[]" value="1"/>
<input type="hidden name="opt[]" value="2"/>
<input type="hidden name="opt[]" value="3"/>

browser will send

opt[]=1
opt[] =2
opt[]=3

as a request to the server;

Its the PHP which is smart enough to interpret this as index array with name of "opt" .

I've just done a simple test (See below) which returns (for me) 200 items in a post array.

<form method="post">
<?php

print count($_POST['opt']);

for($i = 0; $i < 200; $i++){
?><input type="hidden" name="opt[]" value="1" /><?php
}

?>
<input type="submit" />
</form>

I get the impression this is more about the data being sent, or the server itself, than a limitation of PHP.

Well the answer was the Suhoshin security module, after some research i found that acually max_post_vars was set to 200, that was kinda blocking the rest of data from being processed, thanks for all your answer :-)
