If you want to search plain text for valid urls and replace them with
links, here is a regex that may help you out:
<?php
$rx = '
{
\b
# Match the leading part (proto://hostname, or just hostname)
(
# ftp://, http://, or https:// leading part
(ftp|https?)://[-\w]+(\.\w[-\w]*)+
|
# or, try to find a hostname with our more specific
sub-expression
(?i: [a-z0-9] (?:[-a-z0-9]*[a-z0-9])? \. )+ # sub domains
# Now ending .com, etc. For these, require lowercase
(?-i: com\b
| edu\b
| biz\b
| gov\b
| in(?:t|fo)\b # .int or .info
| mil\b
| net\b
| org\b
| [a-z][a-z]\b # two-letter country codes
)
)
# Allow an optional port number
( : \d+ )?
# The rest of the URL is optional, and begins with / . . .
(
/
# The rest are heuristics for what seems to work well
[^;"\'<>()\[\]{}\s\x7F-\xFF]*
(?:
[.,?]+ [^;"\'<>()\[\]{}\s\x7F-\xFF]+
)*
)?
}x';
$text = "blah blah http://www.google.com, text text more text etc";
echo preg_replace ($rx, '<a href="\1">\1</a>', $text);
?>
