Hello,

PHP Code:


			
if(isset($videos[0]['url'])) {

            foreach ($videos as $video)
            {

$yonlen = $video['url'];
echo "<a href=$yonlen>Download</a><br>";
  }

In for each statement, it generates 2 values to the $yonlen, the outputs is

Download
Download

It echos 2 links. I want to make string equals to the latest value in for each statement. How to do that ?

That's hard to say without either seeing a copy of the array it's running off of, or the php that builds the data (and even then the data is probably still necessary).

Ok, is there anyway to make number to the beginning of the values in for each statement ?

If 2 values echoed,

1 - Download
2 - Download

if 3 values echoed,

1 - Download
2 - Download
3- Download

?

I have tried out your code sample and it works good for me with a mockup array

php Code:

<?php

$testarr = array();
$testarr[] = array("url" => "http://trying.com");
$testarr[] = array("url" => "http://trying1.com");
$testarr[] = array("url" => "http://trying2.com");
$testarr[] = array("url" => "http://trying3.com");
$testarr[] = array("url" => "http://trying4.com");
$testarr[] = array("url" => "http://trying5.com");

if(isset($testarr[0]['url'])) {
  foreach($testarr as $video) {
    $yonlen = $video['url'];
    echo "<a href=$yonlen>Download $yonlen</a></br>";
  }
}
?>

It doesn't echo it twice. Maybe if we know the structure of the array like delayedinsanity said it would be easier to help you out.

PHP Code:


			
$nl=0;
if(isset($testarr[0]['url'])) {
  foreach($testarr as $video) {
    $nl++;
    $yonlen = $video['url'];
    echo "<a href=$yonlen>$nl - Download</a></br>";
  }
}
