Associate URL to keywords separated

I have a variable $keywords

开发者_StackOverflowThe content of this variable are words separated by commas or spaces for example:

$keywords= key1,key2,key3

Or

$keywords=key1 key2 key3

the table that I have is:

        <table width="500" border="1">
  <tr>
    <td height='auto'>Keywords: $keywords</td>
  </tr>
</table>

I want explode $keywords in key1 key2 key3 ... And associate to each separated word a predifined URL:

http://miosite.com/search/label/key1
http://miosite.com/search/label/key2
http://miosite.com/search/label/key3

So I want get this:

       <table width="500" border="1">
  <tr>
    <td height='auto'>Keywords: key1,key2,key3</td>
  </tr>
</table>

Where

        key1=http://miosite.com/search/label/key1
        key2=http://miosite.com/search/label/key2
        key1=http://miosite.com/search/label/key3

How to?

You could check for the comma to determine which delimiter to explode on, then put together the string again:

if (strpos($keywords,",") !== FALSE) {
  $keys = explode(",",$keywords);
} else {
  $keys = explode(" ",$keywords);
}
$keywords = "";
foreach ($keys as $key) $keywords .= "http://miosite.com/search/" . $key . "<BR>";

EDIT: Apparently the object is to REMOVE the site address, not add it... no one figured that out. new code:

if (strpos($keywords,",") !== FALSE) {
  $keys = explode(",",$keywords);
} else {
  $keys = explode(" ",$keywords);
}
$keywords = "";
foreach ($keys as $key) $keywords .= str_ireplace("http://miosite.com/search/","",$key) . ",";
$keywords = substr($keywords,0,strlen($keywords)-1);

Hackish, but give that a shot.

Edit: Oh now they need to be linked? LOL

if (strpos($keywords,",") !== FALSE) {
  $keys = explode(",",$keywords);
} else {
  $keys = explode(" ",$keywords);
}
$keywords = "";
foreach ($keys as $key) {
   $newkey = str_ireplace("http://miosite.com/search/","",$key);
   $keywords .= "<a href=\"" . $key . "\">" . $newkey . "</a>,";
}
$keywords = substr($keywords,0,strlen($keywords)-1);

Ok, try that out.

$keywords = explode(',',$keywords);
foreach($keywords as $key) echo("<a href=\"http://miosite.com/search/{$key}\">{$key}</a>");

Keywords:

$keywords = explode(',',$keywords);
$tmpArray = array();
foreach($keywords as $key) {
    $tmpArray[] = 'http://miosite.com/search/label/'.$key;
}

echo implode(",", $tmpArray);

Iam just rewrting by embeddg php within html & taken are of caommas between your links:

 <?php
$keywords = 'key1 key2 key3';
$keywords = preg_split('/[, ]/',$keywords);

foreach($keywords as $key)
    $links[]= "<a href=http://miosite.com/search/{$key}\>{$key}</a>";
    print_r($links);

$keywords  = implode(',',$links);   

?>

<table width="500" border="1">
  <tr>
    <td height='auto'>Keywords: <?php  echo $keywords ;?>
</td>
  </tr>
