split array into comma separated values

Question

I have an array $email like this:

Array
(
    [email_id] => [email protected]
)
Array
(
    [email_id] => [email protected]
)
Array
(
    [email_id] => [email protected]
)

I need this array to be in this format

'[email protected]', '[email protected]', '[email protected]' // RESULT EXPECTED

I am doing this to get my result:

$emails = implode(", " , $email);

But it results in this:

[email protected]@[email protected] // ACTUAL RESULT

What should i do get the result?

Its difficult to use `implode` since all array keys are same. `implode` will work if the array is like `array('mail1', 'mail2')`. For the time being, use the solution put forward by @Hassan. — Tismon Varghese, Sep 17 '15 at 04:55

Try

$email = array(
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
    );

foreach($email as $id)
{
    echo "'".$id['email_id']."',";
}

Thanks Hassaan this works. but can it be like: '[email protected]', '[email protected]', '[email protected]' . As now it is coming as [email protected], [email protected], [email protected]. Thanks in advance – Aashi Sep 17 '15 at 05:00
thanks. It gives result with a coma after last email also. like this: '[email protected]','[email protected]','[email protected]', which is wrong. I dont need comma at last. – Aashi Sep 17 '15 at 05:36

I'm using Hassaan's technique :

$email = array(
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
);

foreach($email as $id){
    $emails .= $id['email_id'].",";
}

$emails = substr($emails, 0, strlen($emails) -1 );

echo $emails;

With this technique you will not have the last comma.

Or you can use this technique that I found here

$input = array(
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]'),
    array('email_id' => '[email protected]')
);

echo implode(',', array_map(function ($entry) {
  return $entry['email_id'];
}, $input));

Strange!! It should work.

How you have defined your $email array? Can you provide a code structure?

If you have something like this then it will definitely work.

$email = array('email1','email2');
echo implode(", ",$email);

You can try php's csv function for it

<?php

 $file = fopen("email.csv","w");

 foreach ($yourArray as $value)
   {
   fputcsv($file,explode(',',$value));
   }

 fclose($file); 
?>

You could also use array_map to reduce the array of arrays into just an array of strings.

$actualEmails = array_map (function ($e) {
    return $e ['email_id'];
}, $email);
echo "'" . implode ("','", $actualEmails) . "'";
