If you declare your arrays, and set k to 0 first, put quotes around array
values and use the correct limit (you can default to -1), you will get
results, here is code and example (hopefully this helps you)
<?php
function internal_links($str, $links, $limit=-1) {
$pattern=array();
$replace=array();
$k=0;
foreach($links AS $link){
$pattern[$k] = "~\b({$link['phrase']})\b~i";
$replace[$k] = '<a href="'.$link['link'].'">\\1</a>';
$k++;
}
return preg_replace($pattern,$replace,$str, $limit);
}
echo internal_links("süße knuffige Beagle Welpen ab sofort",
array(array('phrase'=>"beagle",
'link'=>"http://google.com";),array('phrase'=>"welpen",
'link'=>"http://wolframalpha.com";)), -1);
Output:
süße knuffige<a href="http://google.com";>Beagle</a> <a href="
http://wolframalpha.com";>Welpen</a> ab

Hello,
thank you all for your help. It seems that I am building the array
wrong. Your code works with that array:
$internal_links = array(array('phrase'=>"beagle",
'link'=>"http://google.com";),array('phrase'=>"welpen",
'link'=>"http://wolframalpha.com";));
I am pulling the data out of a DB and am using this code:
while ($row = mysql_fetch_object($result)){
$internal_links[$row->ID]['phrase'] = $row->phrase;
$internal_links[$row->ID]['link'] = $row->link;
}
You build the array different, could you help me to adapt this on my
code? I tried $internal_links['phrase'][] as well, but that did not help
either.
Thank you for any help,
Merlin
HI Again :-)
the building of my array seems fine. Here is what goes wrong:
If you use this array: $internal_links = array(array('phrase'=>"Beagle
Welpen", 'link'=>"http://wolframalpha.com";), array('phrase'=>"Welpen",
'link'=>"http://google.com";));
Then it will fail as well. This is because the function will replace
"Beagle Welpen" with the hyperlink and after that replace the word
"welpen" inside the hyperlink again with a hyperlink.
Is there a function which will not start looking for the words at the
beginnning of the text for each replacement, but simply continue where
it did the last replacement?
Thank you for any help,
Merlin
