Previous Comments: ------------------------------------------------------------------------ [2013-09-12 14:08:21] leight+bugs dot php at gmail dot com Looking at main/php_variables.c it appears that no attempt is made to discern between nesting levels. I wondered if this was a documentation issue, or a bug with the code not checking nesting. It looks to be the documentation at fault. ------------------------------------------------------------------------ [2013-09-12 13:39:25] gabri dot ns at gmail dot com Description: ------------ From http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars it stated that the limitation is only on each nested level of multidimensional array. But actually, it limit on the root level of variabel. Easy speaking, it count appearance of '&' in input. this script should work since each level only contain 900 var, but it stopped after 1000th appearance of '&' it may be connected to Bug #60728 Test script: --------------- $a = array(); for ($i = 0; $i < 900; $i++) { if ($i != 899) $a['asd'.$i] = "$i"; else for ($j = 0; $j < 900; $j++) $a['asd'.$i]['qwe'.$j] = "$i - $j"; } $a = http_build_query($a); parse_str($a,$b); $b = http_build_query($b); echo count(explode('&',$a))."\n"; echo count(explode('&',$b))."\n"; Expected result: ---------------- 1799 1799 Actual result: -------------- Warning: parse_str(): Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in var://_POST/script on line 9 1799 1000 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65659&edit=1
