[RESOLVED] Alternate array keys and values

[malionette]

Hi, I'm a new member and I would like some help, if possible. I am trying to make a PHP script that will turn X lines of image urls and display 3 images in a row with their array key in the row below, showing up in a HTML table.

The output i'm trying to achieve is

<table>
<tr><td>img1</td><td>img2</td><td>img3</td></tr>
<tr><td>0</td><td>1</td><td>2</td></tr>
<tr><td>img4</td><td>img5</td><td>img6</td></tr>
<tr><td>3</td><td>4</td><td>5</td></tr>
</table>

---

This is what I have so far: I can input my image urls with a space between and display the array key and value.

form.html

<form action="ariel.php" method="post">
<textarea cols="60" rows="10" name="images"> </textarea> 
<br />
<input type="submit" value="submit" />
</form>

ariel.php

<?php 

$array = explode (' ', $_POST['images']);

foreach($array as $key => $value) 
{
echo "$key $array <br />";
}


?>

Any help is greatly appreciated.

Let's do it one step at a time.
1. change the echo to echo $key instead of $array.
2. instead of echo inside the loop, use two variables.
One: you concatenate the image names with spaces into it.
Two: you concatenate the $key values (separated with spaces into it).

did I do that right?

<?php 

$array = explode (' ', $_POST['images']);

foreach($array as $key => $value) 
{
echo "$key" . " $array";
}


?>

<?php 

$array = explode (' ', $_POST['images']);
$im='';
$k='';
foreach($array as $key => $value) 
{
   $im.=' '.$value;
   $k.=' '.$key;
}

echo $im.'<br />',$k;

Now, you have to play with that to make it right.

Hi, thank you for your help, but I figured it out!

Here is my result for those who were curious:

<table><tr>

<?php 

$array = explode (' ', $_POST['images']);

$counted = count($array);

echo $counted;

$tdnum = 0;
$counter = 0;

for ($c = 0; $c <= $counted-1; $c += 1)
{
	echo "<td>".$array[$c]."</td>";

$counter += 1;

if ($counter == 3)
{
echo "</tr><tr>";
for ($run = 1; $run <= 3; $run += 1)
	{
		$tdnum += 1;
		echo "<td>".$tdnum."</td>";
	}
$counter = 0;
echo "</tr><tr>";
}
}
?>

</tr></table>

$array = explode (' ', $_POST['images']);

$counted = count($array);

echo '<table>';

$tdimg = '';
$tdc = '';

for ($c = 1; $c <= $counted; $c ++)
{
$tdimg.='<td>'.$array[$c-1].'</td>';
$tdc.='<td>'.$c.'</td>';
if($c%3==0){
echo '<tr>',$tdimg,'</tr><tr>',$tdc,'</tr>';
$tdimg='';
$tdc='';
}

}
echo '</table>';
</tr></table>
