Just Run this code

        <?php
    $array = array(
                array(
                    array(

                        'blog_id' => 2
                    ),
                    array(
                        'blog_title' => 'What are Mobile App Testing Challenges?',

Answer 2

Depending what you're trying to do (debugging vs tabular display), you can "pretty print" the array with var_export like so:

// Assuming your array is $data
echo '<pre>'.var_export($data, TRUE).'</pre>';

Otherwise, to loop through the array as is with a foreach :

// Assuming your array is $data
foreach ($data as $subdata) {
    // You probably want to check that this is an array for case #3
    if(is_array($subdata)) {
         foreach ($subdata as $valueset) {
             // Check for array validity (not required for example data, but good to be safe)
             if (is_array($valueset)) {
                 foreach ($subdata as $key => $value) {
                     // Print each key, value pair as a row
                     echo $key .' => '.$value . '<br />';
                 }   
             }
         }
    } else {
        // Optional handling of empty set
        echo 'No data to display...';
    }
}

foreach  ($array as $value){
foreach  ($value as $row){
     if (is_array($row)){
            foreach  ($row as $key => $val){
                 echo $key."=>". $val."<br>";
             }///endForeach
         }///endIf
       else {
                echo $row;
      }////endElse
}
}
