How to get specific array value in php - php

Question

I want to output a specific value from array in php
Below is my code and array is $content
<?php
$content = $_POST;
for($i=1; $i < $content['itemCount'] + 1; $i++) {
$name = 'item_name_'.$i;
$quantity = 'item_quantity_'.$i;
$price = 'item_price_'.$i;
$image='item_image_'.$i;
$option='item_options_'.$i;
$total = $content[$quantity]*$content[$price];
}
?>
<?php
print_r( $content );
?>
Output is showing as below:
Array ( [currency] => INR
[shipping] => 0
[tax] => 0
[taxRate] => 0
[itemCount] => 3
[item_name_1] => Our Nest
[item_quantity_1] => 1
[item_price_1] => 1900
[item_options_1] => image: CF01108.jpg, productcode: 602793420
[item_name_2] => Our Nest
[item_quantity_2] => 1
[item_price_2] => 2100
[item_options_2] => image: CF01110.jpg, productcode: 123870196
[item_name_3] => Our Nest
[item_quantity_3] => 1
[item_price_3] => 1800
[item_options_3] => image: CF01106.jpg, productcode: 416267436 )
How to get productcode value in a php variable and echo it?
example:
602793420, 123870196, 416267436

Answer 1

You can get the productcode using explode() function, like this,
$product_code = explode("productcode: ", $option)[1];
Here's the reference:
explode()
So your code should be like this:
<?php
$content = $_POST;
for($i=1; $i < $content['itemCount'] + 1; $i++) {
$name = 'item_name_'.$i;
$quantity = 'item_quantity_'.$i;
$price = 'item_price_'.$i;
$image='item_image_'.$i;
$option='item_options_'.$i;
$product_code = explode("productcode: ", $option)[1];
$total = $content[$quantity]*$content[$price];
}
?>

Answer 2

I would rather suggest this, in case the option of the item will have more values in future.
$option = "image: CF01110.jpg, productcode: 123870196";
$options = explode(",", $option);
echo $product_code = explode("productcode: ", $options[1])[1];
