Edit report at https://bugs.php.net/bug.php?id=68296&edit=1 ID: 68296 Updated by: cmb@php.net Reported by: dave at lyte dot id dot au Summary: \n in path with parse_url() converts to underscore -Status: Open +Status: Verified -Type: Bug +Type: Documentation Problem Package: URL related Operating System: OS X PHP Version: 5.4.34 Block user comment: N Private report: N New Comment: This is not a bug, but rather deliberate albeit undocumented behavior, namely that all control characters in a string passed to parse_url() are replaced by underscores[1]. Therefore I'm changing to doc problem. If you want to have that behavior changed, feel free to start the RFC process[2].

Doing: parse_url($path,PHP_URL_HOST); if $path has a "\n" parse_url returns and _ where the \n was. ------------------------------------------------------------------------ [2016-01-15 08:11:46] simonsimcity at gmail dot com Sorry, I meant related to #52923 ------------------------------------------------------------------------ [2016-01-15 08:11:08] simonsimcity at gmail dot com Is related to #68296 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
