How do I write code without a foreach loop? - php

Question

How do I write this code without a foreach loop? I want to fetch the data from the database, but the key and value are stored in the database.
<?php
$options = get_payment_mode_options();
foreach ($options as $key => $value)
{
echo isset($form_data["personal_info"]) && $form_data["personal_info"]->payment_mode == $key ? $value : "";
}
?>
get_payment_mode_options() is function in helper,
function get_payment_mode_options()
{
return array(
"o" => "Online Payment",
"c" => "Cheque Payment"
);
}

Answer 1

Check this,
$options = get_payment_mode_options();
$paymentmode = isset($form_data["personal_info"]) ? $form_data["personal_info"]->payment_mode : '';
echo $options[$paymentmode];
helper function
function get_payment_mode_options()
{
return array(
"o" => "Online Payment",
"c" => "Cheque Payment"
);
}

Answer 2

<?php
function get_payment_mode_options()
{
return array(
"o" => "Online Payment",
"c" => "Cheque Payment"
);
}
// make a new function
function get_your_result($your_key)
{
if (!$your_key) {
return "";
}
$options = get_payment_mode_options();
if(!array_key_exists($your_key,$options)){
return "";
}
return $options[$your_key];
}
// dummy for test
$form_data["personal_info"] = new stdClass();
$form_data["personal_info"]->payment_mode = "o";
$k = $form_data["personal_info"]->payment_mode;
// ~dummy for test
// echo result
echo "----".PHP_EOL;
echo get_your_result($k).PHP_EOL;
echo "----".PHP_EOL;
