i have an array called $imageArray like this

Array
(
    [0] => 'Dashka'_Darren_Sheehan_1.jpg
    [1] => 'Dashka'_Darren_Sheehan_10.jpg
    [2] => 'Dashka'_Darren_Sheehan_2.jpg
    [3] => 'Dashka'_Darren_Sheehan_3.jpg
    [4] => 'Dashka'_Darren_Sheehan_4.jpg
    [5] => 'Dashka'_Darren_Sheehan_5.jpg
    [6] => 'Dashka'_Darren_Sheehan_6.jpg
    [7] => 'Dashka'_Darren_Sheehan_7.jpg
    [8] => 'Dashka'_Darren_Sheehan_8.jpg
    [9] => 'Dashka'_Darren_Sheehan_9.jpg
    [10] => .
    [11] => ..
    [12] => Aaron_Kidney_1.jpg
    [13] => Aaron_Kidney_10.jpg
    [14] => Aaron_Kidney_11.jpg
    [15] => Aaron_Kidney_12.jpg
    [16] => Aaron_Kidney_13.jpg
    [17] => Aaron_Kidney_14.jpg
    [18] => Aaron_Kidney_15.jpg
    [19] => Aaron_Kidney_16.jpg
    [20] => Aaron_Kidney_17.jpg
    [21] => Aaron_Kidney_18.jpg

and i also have another array called $_names

Array
(
    [0] => 'Dashka'_Darren_Sheehan
    [1] => Beefit_Gyms
    [2] => Aaron_Kidney
    [3] => Dean_Mitchell
    [4] => Colin_O_Neill
    [5] => Keith_McManus
)

if a name in array $_names exists in the $imageArray i want to insert the images for that person into one column of a table like this

<tr>
<?php foreach ($names as $name): ?><th><?php htmlout($name); ?></th><?php endforeach; ?>
</tr>
<tr>
<td><img src="../images/'Dashka'_Darren_Sheehan_1.jpg" width="204"/></td>
    <td><img src="../images/Aaron_Kidney_1.jpg" width="204"/></td>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
</tr>
<tr>
<td><img src="../images/'Dashka'_Darren_Sheehan_2.jpg" width="204"/></td>
    <td><img src="../images/Aaron_Kidney_2.jpg" width="204"/></td>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
</tr>

can anyone help me write the logic for this??

I cant figure it out...

So, the image names will ALWAYS be a name followed by an underscore and a number? Where are you getting these arrays? Are they generated from a database or a file processing routine? I think there is probably a simpler solution to handle this at the time the arrays are created instead of after the fact. I could provide a solution, but I want to see where the data is coming from first so I'm not providing the wrong solution.

Hi PHP folks

this is the logic I came up with so basically foreach within a foreach and then use strpos function and if a match echo out the image, so here's the bones of the code.

the first foreach just gets the last name from the names array assuming it's the last after the last underscore.

<?php
foreach($_names as $value) {

   $parts = explode('_',$value);
   $parts = count($parts);
   $key = $parts;
   
   $last_name = $_names[$key];
   
   foreach($imageArray as $matching_value) {
      
   if(strpos($last_name,$matching_value)) {
    
	  echo $matching_value;
   
   }
   }
}



?>

Yes, you can go with that approach, but as I was trying to find out there is probably a more efficient way to do this with the initial creation of the arrays rather than after the fact.

Yes, you can go with that approach, but as I was trying to find out there is probably a more efficient way to do this with the initial creation of the arrays rather than after the fact.

The above code doesnt seem to work. The first array $_names is created from names in a textarea box and the $imageArray is created from the names of all images in an images folder here is my complete code which might be more helpful.

<?php include_once $_SERVER['DOCUMENT_ROOT'] .
	'/facebook/photoApp/security/includes/helpers.inc.php'; 		
	?>

    <td>row 1, cell 2</td>
</tr>


</table> 
    
	<p><a href="?">New search</a></p>
</body>
</html>

and here is the processing file

<?php
include_once $_SERVER['DOCUMENT_ROOT'] .'/facebook/photoApp/security/includes/functions.inc.php';

if (isset($_GET['action']) and $_GET['action'] == 'search')
{

$user =  $_GET['user'];
$names = $_GET['names'];


$names = nl2br($names);
//red($names);

$names = str_replace ( '<br />' , "\t" , $names );
$_names = str_replace( " " , "_" , $names);

//blue($_names);

$_names = explode("\t",$_names);
$names = explode("\t",$names);


// print_r($_names);
echo "<pre>";
print_r($_names);
echo "</pre>";


if ($handle = opendir($_SERVER['DOCUMENT_ROOT'] .'/facebook/photoApp/images/'.$user)) {
   // echo "Directory handle: $handle\n";
    //echo "Entries:\n";

    /* This is the correct way to loop over the directory. */
$imageArray = array();
    while (false !== ($entry = readdir($handle))) { 
	array_push($imageArray, $entry);
    }
}

sort($imageArray);

echo "<pre>";
//print_r($imageArray);
echo "</pre>";


foreach($_names as $value) {

   $parts = explode('_',$value);
   
   
   
   blue(count($parts));
   $numberOfParts = count($parts);
   
   
   $last_name = $parts[$numberOfParts-1];
   blue($last_name);
   
   
   
   
   
   foreach($imageArray as $matching_value) {
      
   if(strpos($last_name,$matching_value)) {
    
	  echo $matching_value;
   
   }
   }
}


include $_SERVER['DOCUMENT_ROOT'] . '/facebook/photoApp/security/results.html.php';
exit();
}

// Display search form


include $_SERVER['DOCUMENT_ROOT'] . '/facebook/photoApp/security/includes/db.inc.php';


$result = mysqli_query($link, 'SELECT email FROM facebook_user');
if (!$result)
{
$error = 'Error fetching facebook users from database!';
include 'error.html.php';
exit();
}

while ($row = mysqli_fetch_array($result))
{
$users[] = array('email' => $row['email']);
}

include 'searchform.html.php';

?>
