ereg_replace problems....

Hi,

Could you tell me how to change www.yyy.zzz to <a href="http://www.yyy.zzz">. I tried this, but it only works with the first URL the second one won't be linked:

$text = ereg_replace(" (www.[^])", " http://\1",$text);
$text = ereg_replace("((ftp://)|(http://))(([[:alnum:]]|[[:punct:]])*)", "<a href=\"\0\" target=\"_blank\">\0</a>",$text);

This changes also http://xxx.yyy.zzz URLs to hyperlinks. http://xxx.yyy.zzz conversion works perfectly, but www.yyy.zzz conversion won't.

Another problem that I have is allmost similar:

$text = ereg_replace(";b([^]);b", "<b>\1</b>", $text);

This will turn all between ;b and ;b to bold, but if I have more than one pair of ;b ;b tags, it won't work like it should.

The reason for the ;b ;b not being replaced by <B> </B> if there is more than one pair is because the pattern match is not global. I don't know how to fix this with ereg() but you can use preg_match_all() to do a global pattern match with Perl Compatible Regular Expressions.

to replace www.yyy.zzz to http://www.yyy.zzz

try the following

$text = www.yyy.zzz

$text = eregi_replace ("www.yyy.zzz", "http://", $text);

Hope this helps

Hi again,

This will do the linking stuff correctly (I guess):

$text = ereg_replace(" (www.)(([[:alnum:]]|[[:punct:]]))", " http://\1\2",$text);
$text = ereg_replace("(^{www.)(([[:alnum:]]|[[:punct:]])})", "http://\1\2",$text);
$text = ereg_replace(" (ftp.)(([[:alnum:]]|[[:punct:]]))", " ftp://\1\2",$text);
$text = ereg_replace("(^{ftp.)(([[:alnum:]]|[[:punct:]])})", "ftp://\1\2",$text);

$text = ereg_replace(" ((ftp://)|(http://))(([[:alnum:]]|[[:punct:]]))", " <a href=\"\1\4\" target=\"_blank\">\1\4</a>",$text);
$text = ereg_replace("((^{ftp://)|(http://))(([[:alnum:]]|[[:punct:]])})", "<a href=\"\1\4\" target=\"_blank\">\1\4</a>",$text);
