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
