#40947 [NEW]: filter_var_aray() fails with a "common" filter

From: exaton at free dot fr Operating system: WinXP SP2, Debian PHP version: 5.2.1 PHP Bug Type: Filter related Bug description: filter_var_aray() fails with a "common" filter Description: ------------ [Tested on Windows XP SP2 / Apache 2.0.55 and on a Debian with kernel 2.6.16 / Apache 2.0.54 / PHP having the Suhosin-Patch applied]. Hello, While reading http://phpro.org/tutorials/Filtering-Data-with-PHP.html, a tutorial on using the new PHP Filter extension, I came across a simple test case that fails unexpectedly. $a = array(10, "109", "", "-1234", "some text", "asdf234asdfgs", array()); var_dump(filter_var_array($a, FILTER_VALIDATE_INT)); Produces bool(false). I would have expected it to produce the same result at : var_dump(filter_var($a, FILTER_VALIDATE_INT, array( 'flags' => FILTER_REQUIRE_ARRAY ))); which displays array(7) { [0]=> int(10) [1]=> int(109) [2]=> bool(false) [3]=> int(-1234) [4]=> bool(false) [5]=> bool(false) [6]=> array(0) { } } (int values for valid int entries, bool(false) for invalid entries, as shown in the tutorial). The manual entry for filter_var_array() indicates, regarding the second parameter : "This parameter can be also an integer holding a filter constant. Then all values in the input array are filtered by this filter.". I looked at the code of ext/filter in CVS and saw that this behavior seems to be applied, boiling everything down to a single function. I could not follow the code precisely enough (for lack of experience with PHP internals) to locate a significant divergence, however. On another note, the manual entry for filter_var_array() provides a code sample containing some constants which do not appear on the manual entry for the Filter extension ; namely, FILTER_FLAG_ARRAY and FILTER_FLAG_SCALAR. In the manual entry for filter_input_array(), which gives the same code sample, these constants have been changed to the existing FILTER_REQUIRE_ARRAY and FILTER_REQUIRE_SCALAR.
