echo only value name no all in array

i want echo only value name no all.

my array:

$file_list[] = array(
                            'name' => $CI->upload->file_name,
                            'file' => $CI->upload->upload_path.$CI->upload->file_name,
                            'size' => $CI->upload->file_size,
                            'ext' => $CI->upload->file_ext,
                            'image_type' => $imageVar->image_type,
                            'height' => $imageVar->height,
                            'width' => $imageVar->width
                            );
                }

my foreach:

foreach($upload_data as $file) {
    echo '<li><ul>';
    foreach ($file as $item => $value) {
        echo '<li>'.$item.': '.$value.'</li>';
    }
    echo '</ul></li>';
 } 

output now:

• name: Chrysanthemum19.jpg

  file: D:/xampp/htdocs/Siran-mehdi/uploads/Chrysanthemum19开发者_运维百科.jpg

  size: 858.78

  ext: .jpg

  image_type: jpeg

  height: 768

  width: 1024

• name: Desert19.jpg

  file: D:/xampp/htdocs/Siran-mehdi/uploads/Desert19.jpg

  size: 826.11

  ext: .jpg

  image_type: jpeg

  height: 768

  width: 1024

i want this output:

Chrysanthemum19.jpg, Desert19.jpg

see you full class and Controller

class Multi_upload(libraries) CI_Controller

With respect

$names = array();
foreach ($file_list as $file) {
  $names[] = $file['name'];
}
echo implode(',', $names);

Using PHP5.3 you can compact it a little bit more

echo implode(',', array_map(function ($file) {
  return $file['name'];
}, $file_list);

But there is no semantic difference between both.

You're printing all file information data. You want to print only name of it. Here:

foreach($upload_data as $file) {
    echo '<li>' . $file->name . '</li>';
}

Try

foreach($upload_data as $file) {
    echo '<li><ul>';
    foreach ($file as $item => $value) {
        if ($item == 'name'){
             echo '<li>'.$item.': '.$value.'</li>';
        }
    }
    echo '</ul></li>';
 } 

Tjeu

First you need to find the part of your loop that outputs the filename:

echo '<li>'.$item.': '.$value.'</li>';

You only want the value to be displayed when $item is equal to 'name'. You can express that in code like this:

$file['name']

Then, eliminate all the parts of your code that do not contribute to the desired output. Your new code can look like this:

$output = array();

foreach($upload_data as $file) {
    $output[] = $file['name'];
}

echo implode( ',' $output );

Use:

foreach($upload_data as $file) {
    echo '<li><ul>',$file['name'],'</ul></li>';
 } 

try something like this :

foreach($upload_data as $file) {
    foreach ($file as $item) {
        $return[] = $file['name'];
    }
}
echo implode(",",$return);
$to_store_in_db = serialize($return);

Adding serialize
