Parallel Foreach loops

[Miteshsach86]

Hi Guys,

 

I'm really [confused] about this however what I have so far is create a simple HTML form, instructing the end user to enter a list of keywords with links to replace them with in the following format: A keywords followed by a comma and then URL and semicolon:

 

For example:

birds,http://www.birdwatching.com/;

snakes,http://www.whales.com/;

horses,http://www.horse.com/;

 

What I have done next is split each word with its associated url after each newline and then placed all the words into 1 array and all the urls into another array, using the following code:

 

preg_match_all('/(.*),(.*);/',$wordsurls, $phrase);

$wds = $phrase[1];

$rurls = $phrase[2];

foreach($wds as $wd) {

$words_array[] = $wd;

}

foreach($rurls as $rurl) {

$urls_array[] = $rurl;

}

 

All that works perfectly fine but now I wish to search a string to find each of those keywords, and if they exist I would like to replace them with the URL. I believe this can be done using Parallel Array matching but do not know how to go accomplishing this. Could someone please help me?

 

Thank you in advance.

I believe something like this should work (untested):

 

$opt = 'Some String to search';
for($i=0;$i<count($wds);$i++){
    $quote = preg_quote($words_array[$i]);
    $opt = preg_replace("~ $quote ~", $urls_array[$i], $opt); // added spaces to match ONLY words, and not urls
}
echo $opt;
