PHP Add to key in ini file

I have a ini file that I am supposed to add to with PHP Forms. As of right now I have working code to create a section if it does not exist, and replace a value if it exists. The thing I am struggling with is appending.

For Example this is my ini file right now.

[Persons]
names = "travis", "jackson"
color = "blue"

On the PHP side I have a form to insert section, key, and value

Say the input section is Person, the key is color and the value is red.

The new ini file I want should be

[Persons]
names = "travis", "jackson"
color = "blue", "red"

The original code I am trying to modify: (taken from this stack article)

function config_set($config_file, $section, $key, $value) {
    $config_data = parse_ini_file($config_file, true);
    $config_data[$section][$key] = $value;
    $new_content = '';
    foreach ($config_data as $section => $section_content) {
        $section_content = array_map(function($value, $key) {
            return "$key=$value";
        }, array_values($section_content), array_keys($section_content));
        $section_content = implode("\n", $section_content);
        $new_content .= "[$section]\n$section_content\n";
    }
    file_put_contents($config_file, $new_content);
}

My thoughts are just to append to current key, but I am not sure how to do that

EDIT: Attempts of things I have tried

This made zero change to the ini file before modification

function config_set($config_file, $section, $key, $value) {
    $config_data = parse_ini_file($config_file, true);
    $config_data[$section][$key] = $value;
    $new_content = "[$section]\n$value";
    foreach ($config_data as $section => $section_content) {
        $section_content = array_map(function($value, $key) {
            return "$key=$value";
        }, array_values($section_content), array_keys($section_content));
        $section_content = implode("\n", $section_content);
        $new_content .= "\n$section_content\n";
    }
    file_put_contents($config_file, $new_content);
 }

This broke the page

function config_set($config_file, $section, $key, $value) {
    $config_data = parse_ini_file($config_file, true);
    $config_data[$section][$key] = $old_val;
    $new_content = '';
    foreach ($config_data as $section => $section_content) {
        $section_content = array_map(function($value, $key) {
            return "$key=$old_val, $value";
        }, array_values($section_content), array_keys($section_content));
        $section_content = implode("\n", $section_content);
        $new_content .= "[$section]\n$section_content\n";
    }
    file_put_contents($config_file, $new_content);
 }

You could add this condition to check if there is a value inside "color" (key section) and append new value accordingly :

if (empty($config_data[$section][$key])) {
    $config_data[$section][$key] = $value;
} else {
    $config_data[$section][$key] .= ',' . $value;
}

Full code : 

function config_set($config_file, $section, $key, $value) {
    $config_data = parse_ini_file($config_file, true);
    if (empty($config_data[$section][$key])) {
        $config_data[$section][$key] = $value;
    } else {
        $config_data[$section][$key] .= ',' . $value;
    }    
    $new_content = '';
    foreach ($config_data as $section => $section_content) {
        $section_content = array_map(function($value, $key) {
            return "$key=$value";
        }, array_values($section_content), array_keys($section_content));
        $section_content = implode("\n", $section_content);
        $new_content .= "[$section]\n$section_content\n";
    }
    file_put_contents($config_file, $new_content);
}
