=("|\')?([^ "\']*)("|\')?.*>([^<]*)</A>'

[lecichy]

Hello.


Well, I found this piece of code on php.net. Thats fine but where can i find
explanation for all these ("|\')?([^ "\']*)("|\')?.*>([^<]*)' syntax so that
I can construct my own rules for all kind of eregi preg and oter match
functions ?



Transform HTML links into plain-text "links" with the URL visible

function AHREF2text($str ing) {
return eregi_replace(' <A .*HREF=("|\')?([^ "\']*)("|\')?.*>([^<]*)</A>',
'[\\4] (link: \\2)', $string);
}

Re: =(&quot;|\')?([^ &quot;\']*)(&quot;|\')?. *&gt;([^&lt;]*)&lt;/A&gt;'

And another simple question, maybe its the same answer.
whats the syntax of eregi_replace if I want to match ( remove in this
case ) few strings, not one:
eregi_replace (("stringone" && "stringtwo" ), "", $source)
Or it just requires whole eregi expression each time ?
This ofcourse doesn't work but hope you know what I mean.

You better switch to preg_ functions. They're faster and more powerful
than ereg*

Try
<?php
$destin = preg_replace('/string(?:one|tw o)/i', '', $source)
?>


/string(?:one|tw o)/i -- means:

/ # start of regex
string # match "string literally"
(?: # start a group but don't grab (no need for that)
one # literal "one"
| # OR
two # literal "two"
) # end group
/i # end regex, but match without regard to case


see the preg_ function at

http://pt.php.net/manual/en/ref.pcre.php

Also try regex-coach from http://weitz.de/regex-coach/



using the PCRE_EXTENDED modifier (x) you can put the regex and
the comments in the source file

<?php
function AHREF2text($str ing) {
return preg_replace(
'@ # start of regex
<a[ ] # literal "<a " (notice the space)
[^<]* # any number of (any characters EXCEPT "<")
href= # literal "href="
("|\')? # optional double OR single quote (grabbed)
([^"\']*) # any number of (anything BUT double
## OR single quote) (grabbed)
("|\')? # optional double OR single quote (grabbed)
[^>]* # any number of (any characters EXCEPT ">")[color=blue]
> # a literal ">"[/color]
([^<]*) # any number of anything BUT "<" (grabbed)
</a> # literal "</a>"
@ix', # end regex, caseless and extended

'[\\4] (link: \\2)', $string);
}

// =============== ==============

$x = 'At <a href="http://mysite.example. com/">my site</a> there
are many <a href="http://examples.exampl e.com/">examples</a> :)';

echo $x, '<hr />', htmlentities($x ), '<hr />', AHREF2text($x);
?>

Moms have more power than all the regex gurus put together!
