help with variable loop

[dreamwest]

I have a group of links but need to add a number next to each

 

$links = "http://site.com<br>
            http://site2.com<br>
            http://site3.com<br>"; //etc..up until 25 links

 

I thought of using strreplace and explode but they will both replace - for example the <br> with the same number, but i need to count how many <br> tags there are in the variable and add a niumber next to each

 

So basically i need the output to be:

 

$links = "http://site.com<br> 1
            http://site2.com<br> 2
            http://site3.com<br> 3"; //etc..up until 25 links

$temp = array();
$links = explode('<br>', $links);
$number = 1;
foreach ($links as $link) {
    $link = trim($link); // tabs, newlines, .. as noted on: http://us2.php.net/manual/en/function.trim.php
    $temp[] = $link . nl2br("\n") . $number++;
}

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

If each url is followed by a <br>, you can explode by the <br>, then loop through the array to add it back in with the number:

 

$linksArray = explode('<br>', $links);
$counter = 1;
$result = '';

foreach ($linksArray as $l) {
    $result .= $l . '<br> ' . $counter . ' ';
    $counter++;
}

I cant figure out whats going on with this, the out put is:

 

2 loops

http://site.com
http://site2.com
http://site3.com
http://site.com
1 http://site2.com
2 http://site3.com
3
4 http://site.com
http://site2.com
http://site3.com
http://site.com
1 http://site2.com
2 http://site3.com
3
4

 

The code i used is:

 

$links = "http://site.com<br>
            http://site2.com<br>
            http://site3.com<br>";

$linksArray = explode('<br>', $links);
$counter = 1;
$result = '';

foreach ($linksArray as $l) {
    $links .= $l . '<br> ' . $counter . ' ';
    $counter++;
}
echo $links;

 

For 2 loops the out put should be:

 

http://site.com<br> 1

http://site2.com<br> 2

[J.Daniels]

$links = "http://site.com<br>
            http://site2.com<br>
            http://site3.com<br>";

$linksArray = explode('<br>', $links);
$counter = 1;
$links = '';

foreach ($linksArray as $l) {
    if ($l != '') {
        $links .= $l . '<br> ' . $counter . ' ';
        $counter++;
    }
}
echo $links;

 

You have to reset $links before adding the result.  Also, if you don't want the last blank line, check to see if it is an empty string.
