ID: 21920 Updated by: [EMAIL PROTECTED] Reported By: corinl at gmx dot de -Status: Verified +Status: Bogus Bug Type: Documentation problem PHP Version: 4.3.0 New Comment:
PHP 4.3.0 is old enough so there is no need to document behavior prior to it. Previous Comments: ------------------------------------------------------------------------ [2004-04-08 22:31:40] [EMAIL PROTECTED] >From PHP 4.3.0, array_unique() returns the key of the first related value from the unsorted array. http://cvs.php.net/diff.php/php-src/ext/standard/array.c?r1=1.167&r2=1.168&ty=h In addition, prior to PHP 4.0.5 used REGULAR SORT, not STRING SORT, and PHP 4.0.4 also compared type (broken behavior) http://cvs.php.net/diff.php/php-src/ext/standard/array.c?r1=1.76&r2=1.77&ty=h http://cvs.php.net/diff.php/php-src/ext/standard/array.c?r1=1.86&r2=1.87&ty=h ------------------------------------------------------------------------ [2003-02-05 02:23:13] [EMAIL PROTECTED] Both examples were wrong but have been updated to reflect current (4.3.0) behavior. Am leaving this open until someone can figure out when (or if) the behavior changed. Apparently the second example was from 4.0.6 but hmm, this is odd. Nothing in NEWS reflects a change. http://cvs.php.net/cvs.php/phpdoc/en/reference/array/functions/array-unique.xml And a historical reference: http://cvs.php.net/cvs.php/phpdoc/en/functions/array.xml ------------------------------------------------------------------------ [2003-01-28 11:23:03] [EMAIL PROTECTED] Maybe the documented example was created on a PHP 4.0.4 box ;) ------------------------------------------------------------------------ [2003-01-28 10:47:49] [EMAIL PROTECTED] The docs : [snip] Note that keys are preserved. array_unique() sorts the values treated as string at first, then will keep the first key encountered for every value, and ignore all following keys. It does not mean that the key of the first related value from the unsorted array will be kept. [/snip] I get the users result on Windows(4.3.0-dev), RH 6.2(4.3.0-dev), Debian 3.0 (5.0.0-dev). The docs should be changed. ------------------------------------------------------------------------ [2003-01-28 10:31:19] [EMAIL PROTECTED] I get: php -v PHP 4.3.0 (cli) (built: Jan 8 2003 16:10:13) Copyright (c) 1997-2002 The PHP Group Zend Engine v1.3.0, Copyright (c) 1998-2002 Zend Technologies php test.php Array ( [a] => grün [0] => rot [1] => blau } Friedhelm ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
