Loop through associative array and assign values - php

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.

Answer 1

$instructions = array (
array("step_no"=>"1","description"=>"Ensure that you have sufficient balance"),
array("step_no"=>"2","description"=>"Approve the request sent to your phone")
);
foreach($instructions as $instruction) {
echo $instruction['step_no'] . '. ' . $instruction['description'] . "\n";
}
If it's HTML you may want to use <ol> and <li>.

Answer 2

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/>";

Answer 3

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.
