Replace all links with url index?

[Fredrik Jonson]

Hello,

I'm writing a newsletter poster for a website. I have some
html news items which I want to turn into plain text and prettify
before emailing it.

Now, i have found wordwrap and strip_tags so the only problem
remaining is the links. Below you see what I like to see, but
I haven't got a clue how to get there.

$html = '<p>My <a href="http://go.there/stuff">link somewhere</a>.</p>';
doSomeMagic($html);
echo $html;

After doSomeMagic I'd like the echo to look like this:

My link somewhere[1].
[1] http://go.there/stuff

That is, in the text I want an reference, and below the entire paragraph
i want a link index.

I'd be grateful for any hints how to get there.

Hi Fredrik,

I wrote something a while ago that does that:

<?php
$lcount=0;
$globMatches;

function increase(){
global $lcount;
$lcount++;
return $lcount;
}

function stripLinks($origtext){
global $globMatches;
$filteredtext = "";
$pattern = "/(<a href=\")(.+?)(\")(\s*)(>)(.+?)(<\/a>)/e";
$replace = "'\\6['.increase().']'";
preg_match_all($pattern, $origtext, $matches);
$globMatches[] = $matches;
$filteredtext = preg_replace($pattern, $replace, $origtext);
return $filteredtext;
}

function makeLinkFooter(){
global $globMatches, $lcount;
$appendix = "";
$m=1;
for($j=0;$j<$lcount;$j++){
for($i=0;$i<count($globMatches[$j][2]);$i++){
$appendix .= "[".$m."] ".$globMatches[$j][2][$i]."<br>\n";
$m++;
}
}
return $appendix;
}

$html = 'My <a href="http://go.there/stuff">link somewhere</a>.';
$html_new = stripLinks($html);
$footer = makeLinkFooter();

echo $html_new."\n\n";
echo $footer."\n";
?>

Hope this helps;
JOn

Yes, thanks. I had already started working with some code using
preg_replace_callback, which I of course stumbled on _right_ after
I posted my first message. But I had problems with the regex, which
with some hints from your code I got to work.

<?php
$current_link = 0;
$link_index;

function link_indexer($matches)
{
global $link_index;
global $current_link;
// save the match in the global index
$link_index[$current_link] = $matches[1];
$current_link++;
// return the "plain" text with a reference.
return $matches[2] . '[' . $current_link . ']';
}

$html = '<p>My <a href="http://go.there/stuff">link somewhere</a>.</p>';

$text = preg_replace_callback(
'/<A href=\"(.+?)\">(.+?)<\/A>/i',
'link_indexer',
$html);
// remove other html tags
strip_tags($text);

// print the plain version
echo $text; // renders: "My link somewhere[0]."

// print the index
$i = 0;
foreach ($link_index as $link) {
print "[$i] $link\n";
$i++;
}
// renders: "[0] http://go.there/stuff"
?>
