Loop through associative array and assign values

Question

I have an array:

$instructions = array (
array("step_no"=>"1","description"=>"Ensure that you have sufficient balance"),
array("step_no"=>"2","description"=>"Approve the request sent to your phone")
);

What I want is to loop through this array, which I have done, but I am now confused because I don't know how to get the output I desire.

foreach ($array as $key => $value) { 
//echo $key . "\n"; 
foreach ($value as $sub_key => $sub_val) {      
    if (is_array($sub_val)) { 
        //echo $sub_key . " : \n"; 
        foreach ($sub_val as $k => $v) { 
            echo "\t" .$k . " = " . $v . "\n"; 
        } 
    } else { 
        echo $sub_key . " = " . $sub_val . "\n"; 
    } 
  } 
}

The above code loops through the array, but this line of code:

echo $sub_key . " = " . $sub_val . "\n";

gives me:

step_no = 1 description = Ensure that you have sufficient balance step_no = 2 description = Approve the request sent to your phone

when I change it to:

echo $sub_val . "\n";

it gives me:

1 Ensure that you have sufficient balance 2 Approve the request sent to your phone

But I what I truly want is:

1. Ensure that you have sufficient balance 
2. Approve the request sent to your phone

Is this possible at all? Thanks.

$instructions = array (
    array("step_no"=>"1","description"=>"Ensure that you have sufficient balance"),
    array("step_no"=>"2","description"=>"Approve the request sent to your phone")
);

foreach($instructions as $instruction) {
    echo $instruction['step_no'] . '. ' . $instruction['description'] . "\n";
}

If it's HTML you may want to use <ol> and <li>.

It smells like you are not running this script in command line but in browser. If so, then \n makes no visual effect (unless within <pre> block) and you u must use HTML tag <br /> instead. Also, drop concatenation madness and use variable substitution:

echo "{$sub_key}. = {$sub_val}<br/>";

You can simple achieve this way

<?php
    $instructions = array (
                           array("step_no"=>"1","description"=>"Ensure that you have sufficient balance"),
                           array("step_no"=>"2","description"=>"Approve the request sent to your phone")
);

   foreach($instructions as $instruction){

       echo $instruction['step_no'].'. '.$instruction['description'].PHP_EOL;
   }
?>

Alway keep it simple.

I'm a huge fan of keeping codes simple, I'm not very good at all with loops and arrays, that's why I browsed a lot of sites just to come up with that code, it seemed to work, that's why I decided to use it with trying to make further adjustments to it to avoid spoiling it.
