ikin Posted November 4, 2010 Share Posted November 4, 2010 Well I have never learn'd Regex, so I need some help with it. I'm trying to remove the |file = in the string (the code is in wikipedia format): {{Infobox Music |name = Body Parts |release = [[31 January]] [[2005]] |update = Creature of Fenkenstrain |members = Yes |location = Experiment Dungeon |skillrequired = |questrequired = [[Creature of Fenkenstrain]] |hint = This track unlocks at the dungeon south-east of Fenkenstrain's Castle. |file = }} oh if it were just to do str_replace it would be love but no, they have to use multi spaces sometimes :@... Like: | file = Etc but only spaces nothing else, So I was trying to replace it (as I said): echo(preg_replace("/(\|)(\s+)(\file)(\s+)(\=)/i", "", $e)); But it didn't work (Yes I tried with many...) So I come here to ask for help. Thanks for reading. Quote Link to comment https://forums.phpfreaks.com/topic/217732-damn-you-regex/ Share on other sites More sharing options...
JAY6390 Posted November 4, 2010 Share Posted November 4, 2010 $result = preg_replace('/\|\s*file\s*=/im', '', $e); Quote Link to comment https://forums.phpfreaks.com/topic/217732-damn-you-regex/#findComment-1130192 Share on other sites More sharing options...

salathe Posted November 4, 2010 Share Posted November 4, 2010 You were nearly there. \f means something special when within a double-quoted string, just remove that slash and it would have worked. For what it's worth, you also (obviously, after JAY6390's post) need any of the parentheses nor a slash before the equals character. It would also be good to "anchor" the expression so that the | can only be matched at the start of a line. Also, read up on the m pattern modifier that JAY6390 introduced and see if you think it is necessary or not.

JAY6390 Posted November 4, 2010 Share Posted November 4, 2010 I did actually mean to put in the ^ anchor, oops. True the | doesn't need a \ before it, but only if the ^ is before it. if left without the ^ anchor and no \ before the |, it won't be a valid regex. I generally escape all special characters just out of habit to be honest, even when not needed inside character classes etc Quote Link to comment https://forums.phpfreaks.com/topic/217732-damn-you-regex/#findComment-1130202 Share on other sites More sharing options...
