How does the user want PHP to recognize and handle the special {soh #cbffad} tag in the conversion process?

The user wants PHP to recognize and handle the special {soh #cbffad} tag by creating a custom function that will search for this tag in the input string, replace it with a specific value, and return the modified string. This can be achieved by using the str_replace function within a custom function that takes the input string as a parameter.

function handleSpecialTag($input) {
    $specialTag = '{soh #cbffad}';
    $replacementValue = 'Special Value';
    
    $output = str_replace($specialTag, $replacementValue, $input);
    
    return $output;
}

$inputString = 'This is a sample string with {soh #cbffad} tag.';
$outputString = handleSpecialTag($inputString);
echo $outputString;
