#31301 [Bgs]: trim() does not trim single whitespace variables

ID: 31301 User updated by: aitrus at tresgeek dot net Reported By: aitrus at tresgeek dot net Status: Bogus Bug Type: Strings related Operating System: Linux PHP Version: 4.3.10 New Comment: grr! thanks for your time. =) Previous Comments: ------------------------------------------------------------------------ [2004-12-26 20:28:36] derick@php.net Still not a bug :) &nbsp; gets converted not to a space (ascii 32) but to a non breaking space, which matches to ascii 160. And that character is not always a non breaking space in every character set so trim() should not trim it by default. ------------------------------------------------------------------------ [2004-12-26 18:34:37] aitrus at tresgeek dot net I apologize, my example was too simple and did not reproduce the problem: $foo = "&nbsp;"; $foo = html_entity_decode( $foo, ENT_QUOTES ); $foo = trim( $foo ); echo "x{$foo}x"; output is: 'x x' ------------------------------------------------------------------------ [2004-12-26 11:34:12] derick@php.net Works fine here: derick@kossu:~$ cat bug31301.php <?php $foo = " "; $foo = trim( $foo ); echo "x{$foo}x"; ?> derick@kossu:~$ php-4.3dev bug31301.php xx ------------------------------------------------------------------------ [2004-12-26 07:44:34] aitrus at tresgeek dot net updated OS ------------------------------------------------------------------------ [2004-12-26 07:36:57] aitrus at tresgeek dot net Description: ------------ When passed a string variable with a single space as its contents, trim() returns a variable with a single space as its contents. Reproduce code: --------------- $foo = " "; $foo = trim( $foo ); echo "x{$foo}x"; -- output is: 'x x' Expected result: ---------------- trim() should return a empty string (or false). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31301&edit=1
