PHP 4.0 Bug #9963 Updated: strtr behaves differently than unix tr

ID: 9963 User Update by: chris_abbey@yahoo.com Status: Open Bug Type: Strings related Description: strtr behaves differently than unix tr I'm using the preg_replace routine to get equivalent function. Previous Comments: --------------------------------------------------------------------------- [2001-03-23 21:55:06] chris_abbey@yahoo.com $str = "abcdefghij"; $str = strtr($str, "abcdef", "XYZ"); results in "XYZdefghij" where as in standard unix: echo "abcdefghij" | tr 'abcdef' 'XYZ' would output "XYZZZZghij" because the last character is repeated automatically. Some versions will return "XYZXYZghij" because they reuse the second string, but I'm not if that's the "correct" behaviour, or if the fisrt one is... for what I'm trying to accomplish it doesn't matter though. An example of why this is a problem... $obj_nom = "The Foo-Object"; $file_nom = strtr($obj_nom, " -", ""); // or ..., ''); One would expect this to assign "TheFooObject" to $file_nom... but instead no translation is performed. This would also be the same as: tr -d ' -' which is logically equivalent to: tr ' -' '' There does not appear to be a native php function to do the same thing, infact the editors of the user coments have a couple times told people to use strtr or one of the regexp replacement libraries to accomplish this... not knowing that none of them seem to do so. --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=9963
