Edit report at https://bugs.php.net/bug.php?id=61532&edit=1 ID: 61532 Updated by: johannes@php.net Reported by: iblue at gmx dot net Summary: Apostrophe modifier in *printf is broken Status: Open Type: Bug Package: Strings related Operating System: GNU/Linux PHP Version: 5.4.0 Block user comment: N Private report: N New Comment: The current behaviour seems to be in line with what libc does, both on Linux and Solaris (and gcc and suncc): $ cat test.c #include <stdio.h> void main() { printf("%'.09i\n", 123); } $ gcc -otest test.c $ ./test 000000123 Previous Comments: ------------------------------------------------------------------------ [2012-03-27 21:28:09] iblue at gmx dot net Description: ------------ When I use the apostrophe (') modifier to select a padding character in printf, it behaves buggy, when the padding length itself is prefixed by zeroes. Test script: --------------- <?php echo sprintf("%'.9s\n", "foo"); echo sprintf("%'.09s\n", "foo"); Expected result: ---------------- ......foo ......foo Actual result: -------------- ......foo 000000foo ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61532&edit=1
