preg_replace UTF-8

[techboy999]

Hello guys

I sitting here and try to get a string in to links, I am almost there just problem I have is that some special characters will not link to the link

I need get the the preg_replace to use UTF-8, I know it's possible with a parameter /u, but I cant find out where to place it

 

Here is the code:

$str = $message4;

// Url Template
$template = '<a href="search.php?q=%1$s">%1$s</a>';

// Replace Words
echo preg_replace("/(?!(?:[^<]+>|[^>]+<\/a>))\b([a-å]+)\b/is", sprintf($template, "\\1"), $str);

Before that,

[a-å]+

will not work: character ranges work on bytes (or Unicode codepoints) and that range will cover far more than just letters.

 

So you're trying to link all words. I'd go for

[\pL']+

to match letters and apostrophes.

 

As for getting Unicode mode, that's the /u flag. "Flags" go after the ending delimiter - you're using two of them already...

Hi

 

It works almost with the [\pL']+ but I have 2 words that always not link the special characters the words are så and må and also også, you have any idea to fix that ?

Thanks in advance

It should work fine. Are you sure the text is in UTF-8 encoding? What does bin2hex($str) show?

That's not UTF-8. Probably ISO 8859-1 but I can't tell for sure right now.
