preg_replace with $this->xyz

[Anon]

Hey,

I need to do some substitutions inside a class-function, where I have a line reading sth. like this:

preg_replace("/{(\w+)}/e", "$this->\1", $this->text);

$this->foo is "bar", so "{foo}" in $this->text should be replaced with "bar".

Unfourtunately, I only get a parse error saying "parse error, expecting `T_STRING' in ..."

What the hell??

Can anybody help me with that or suggest any workarounds?

Thanks!!

Hi,

That's a parse error.

There must be a missing closing curly brace '}' in your class code or a ;

Really? Help me out, where exactly do you think is missing that brace?:

preg_replace("/{(\w+)}/e", "$this->\1", $this->text);

It must be somewhere else in the class code.

The syntax I'm using for something similar is:

preg_replace("/<# ([^.]*) #>/", $this->options("\1") , $text);

It parses correctly, but it's still not giving me the desired results. It's actuall passing the string "\1" into the options methods, not what \1 is actually a placeholder for.

sorry to kick this one up again, but i found something that did the trick for me in a similar situation .. you can use $1 instead of \1, etcetera.

like this :

$html = preg_replace("/[url=(^\[]*)\\[\/url]/e", 'Utils::getUrl("$1","$2")', $html);

this is for an linkname syntax, like in ubb code.

this may be of use to anyone .. (it cost me a day to find out (-: )
