Put a lang function inside of a php string - php

Question

Trying to do a translation of my MySQL DB to PHP.
Here's the code:
$sql = "SELECT Name, Price FROM utf WHERE Name LIKE 'K%'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<div class=\"CSSTableGenerator style=\"width:600px;height:150px;\"><table><tr><th>Name</th><th>Price</th></tr></div>";
// output data of each row
while($row = $result->fetch_assoc()) {
$name = str_replace('K', 'Karambit', $row['Name']);
echo "<tr><td>".$name."</td><td>".$row["Price"]." ".$row["Trend"]."</td></tr>";
}
echo "</table>";
So Select, Filter by signature character, and then translate.
Now, I have a lang.php file which has the translations.
Here it is:
<?php
function lang($phrase){
static $lang = array(
'ba' => 'Bayonet',
'ka' => 'Karambit'
);
return $lang[$phrase];
}
?>
How do I put it in this line:
$name = str_replace('K', 'Karambit', $row['Name']);
and replace 'ka' => 'Karambit' with 'Karambit'?
Non of these have worked:
//attempt 1
$name = str_replace('K', 'lang('ka');', $row['Name']);
//attempt 2
$name = str_replace('K', '$lang('ka');', $row['Name']);
//attempt 3
$word = echo lang('ka');
$name = str_replace('K', '$word', $row['Name']);

Answer 1

Don't put function calls in quotes, just use:
$name = str_replace('K', lang('ka'), $row['Name']);
//^^^^^^^^^^ See here
Also to give you another option:
You can store your search => replace values into an array like this:
$searchReplace = [
"ba" => "Bayonet",
"ka" => "Karambit",
];
And then you can simply use strtr() to replace it, e.g.
$name = strtr($row['Name'], $searchReplace);
