Damn you regex...

[ikin]

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.

$result = preg_replace('/\|\s*file\s*=/im', '', $e);

No problem

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.

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

True the | doesn't need a \ before it

No-one said it doesn't (it does).

Upon second inspection, no they did not  Clearly today has been too long already lol
