Edit report at https://bugs.php.net/bug.php?id=70635&edit=1 ID: 70635 User updated by: roger21 at free dot fr Reported by: roger21 at free dot fr Summary: an assignment operation modifies the source array Status: Not a bug Type: Bug Package: Arrays related Operating System: linux debian 7.9 (old stable) PHP Version: 5.4.45 Block user comment: N Private report: N New Comment: holy cow, that makes sense and that sucks (i mean, i suck at php) thanks a lot Previous Comments: ------------------------------------------------------------------------ [2015-10-05 18:42:54] requinix@php.net After the first foreach ends, $color will still be a reference to the last element in the $colors array. When the second foreach starts it will reuse $color, thus updating that last element each step through the loop. Don't use a reference, or unset($color) after the first loop. ------------------------------------------------------------------------ [2015-10-04 11:16:53] roger21 at free dot fr Description: ------------ libapache2-mod-php5 5.4.45-0+deb7u1 php.ini not modified (same bug with the cli) the problem : the assignment operation in the foreach loop from one array to another modifies the source array (it shouldn't) - it does not if the source array is passed by reference in the foreach loop (it shouldn't either in this case but it could have) the test script is long because the source array is long (147) but the code is simple and obvious i don't know if the source array matters but i guess it does, otherwise the bug would have already been found Test script: --------------- http://roger21.free.fr/test/test_colors.txt Expected result: ---------------- 145 yellow 146 yellowgreen 145 yellow 146 yellowgreen 145 yellow 146 yellowgreen Actual result: -------------- 145 yellow 146 yellowgreen 145 yellow 146 yellowgreen 145 yellow 146 yellow ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70635&edit=1
