Dead6re Posted October 29, 2008 Share Posted October 29, 2008 Hello, I'm having a problem trying to match pipe characters if there is more than one: e.g. {hyperlink|ahref|text} Using: $this->contents = preg_replace_callback('/\{[A-z0-9\-\|,\.\/]+\}/', array($Template, 'replace'), $this->contents); Link to comment https://forums.phpfreaks.com/topic/130598-only-matching-a-pipe-character-once/ Share on other sites More sharing options...
ddrudik Posted October 29, 2008 Share Posted October 29, 2008 \|(?=[^{}]*}) Although I suspect your question is a different one than that. $this->contents = preg_replace_callback('/\{([^}]*)\}/', array($Template, 'replace'), $this->contents); then in replace($match): $matches=explode('|',$match[1]); loop through each $matches to do your replacements.

Dead6re Posted October 29, 2008 Author Share Posted October 29, 2008 Okay, I think I need to explain a bit more. I have a template class in PHP that should replace values within {} brackets. Inside those brackets, the characters A-z, 0-9, Hyphen (-), Pipe (|), Comma (,), Full-stop (.) & Forward Slash (/). Using the expression tester here using my expression it works: http://www.gskinner.com/RegExr/ However using it in PHP does not. For some reason matching {} brackets from my file does not work. It seems that having a range of A-z 0-9 matches more than one character However matching a special character seems to match it once and not more. e.g. It should match all expressions within the {} brackets below [in navy] (Simple HTML) <html> <head> <title>{title}</title> {css|style.css,layout.css} </head> <body> {hyperlink|ahref|text}{randomtext} </body> </html> Link to comment https://forums.phpfreaks.com/topic/130598-only-matching-a-pipe-character-once/#findComment-677621 Share on other sites More sharing options...
