PHP Two Dimensional Array Convert to Comma Separated String

Now we will take the example of a two-dimensional array. In this example, we will convert two-dimensional array to comma separate string.

<?php
     // Two Dimensional array
    $array = array (
      array ('01','03','02','15'),
      array ('05','04','06','10'),
      array ('07','09','08','11'),
      array ('12','14','13','16')
    );
 
    $tmpArr = array();
    foreach ($array as $sub) {
      $tmpArr[] = implode(',', $sub);
    }
    $result = implode(',', $tmpArr);
 
    echo $result;

    }
    $result = implode(',', $tmpArr);
 
    echo $result;
?>

PHP Implode – Multidimensional Array to Comma Separated String

Here you will learn how you can convert multidimensional array to comma separated string.

<?php
 
$multi_dimensional_array = array(
  
array(
  
'Name' => 'PHP',
  
'Email' => 'php@gmail.com'
  
),
  
array(
  
'Name' => 'Java',
  
'Email' => 'java@gmail.com'
  
)
  
);
 
echo implode(', ', array_map(function ($string) {
  
return $string['Name'];
  
}, $multi_dimensional_array));
 
?>
