return function in class

[Jeff]

I had this little bit of code:

function parseTemplateData($file){
$file2=preg_replace_callback(
"/<edit(.*?)>/s",
"parseEditTag",
$file);
echo $file2;
}

and that did what I needed, so I thought I'll put it in a class:

class FOO{

public function parseTemplateData($file){
$file2=preg_replace_callback(
"/<edit(.*?)>/s",
"parseEditTag",
$file);
echo $file2;
}

public function parseEditTag($tag_content){
....

}

It is, of course looking for parseEditTag *outside* the class. So, I
thought:

$file2=preg_replace_callback(
"/<edit(.*?)>/s",
"$this->parseEditTag",
$file);

Which failed.

Then I thought:

$file2=preg_replace_callback(
"/<edit(.*?)>/s",
EDIT_PAGE::parseEditTag(),
$file);

Now that calls the function, but doesn't pass in the match.

So I thought I'd try to use create_function. But even if I could
figure out how to pass in the matches, I still can't get it to call the
method in the class.

So, I'm thinking there must be another plan. Or another beer.

Maybe I'm just thinking too perl!

Valid callbacks are:
$callback = 'function_name';
$callback = array($instanceofObject,'method_name');
$callback = array('ClassName','static_method_name'));

If you went to the manual for preg_replace_callback:
http://nl2.php.net/preg_replace_callback
...and clicked on 'callback', you end up here:
http://nl2.php.net/manual/en/languag...ypes..callback

<?php
class Foo{
function test(){
echo preg_replace_callback('/a/',array($this,'funcname'),"acac");
echo preg_replace_callback('/a/',array('Bar','funcname'),"acac");
echo preg_replace_callback('/a/','funcname',"acacacaca");
}
function funcname(){
return 'b';
}
}
class Bar{
static function funcname(){
return 'd';
}
}
function funcname(){
return 'e';
}
$f = new Foo();
$f->test();
?>

Thanks for the following example, it's perfectly clear.

And since the next thing on my list to learn was "call_user_func", I've
already learned that with the 'callback' lesson!
