ereg_replace + function?

[mrberti]

Hello,

I'm attempting to pass a user-defined function in an ereg_replace, but having difficulties.

 

$text = "blah 9 blah";
echo eregi_replace("([1-9])", doSomething('\\1'), $text);

function doSomething($i) {
echo $i."<br />";
if($i == "9") return "foo";
else return "~$i~";
}

 

outputs...

\1
blah ~9~ blah

 

So in doSomething(), $i goes through correctly on the RETURN, but not on the ECHO or IF... I guess I am handling $i incorrectly?

Any help is appreciated.

Try a preg_replace:

 

$text = "blah 9 blah";
echo preg_replace("/([1-9])/se", "doSomething('\\1')", $text);

function doSomething($i) {
    echo $i . "<br />";
    if ($i == "9") return "foo";
    else return "~$i~";
}

Thanks! I took your code and applied to perfectly to my script, but I encountered another problem. How do you do an 'except' clause in preg? For example, I would like to do "match any single character (letter, number, special character, or otherwise.. anything) except Z"?

Add a ^ to a character set.

 

Example regex: [^zZ]

Would match any character except a lowercase or capital Z

OK... I'm trying to find and replace links in text. for example...

 

The [[G||Chrono Trigger]] soundtrack proved extremely popular with fans. Mitsuda worked on four more titles for Squaresoft, the last being [[G||Xenogears]] in 1998.

 

I would like to find, analyze, and replace [[G||...]] with a link. So how would you do a preg match? So far I have:

/\[\[G\|\|([- a-z0-9]+)\]\]/ise

but I want to make an expression that says "match ANY character within the brackets" (including special and foreign characters that may be there).

 

Thanks again.
