Convert to camel case and snake case in php

Convert to camel case and snake case in php:

In php, if we want to convert camel case to snake case and vise versa then we have to use following methods:

public static function convertToCamelCase($array) {
        $converted_array = [];
        foreach ($array as $old_key => $value) {
            if (is_array($value)) {
                $value = static::convertToCamelCase($value);
            } else if (is_object($value)) {
                if (method_exists($value, 'toArray')) {
                    $value = $value->toArray();
                } else {
                    $value = (array) $value;
                }
                $value = static::convertToCamelCase($value);
            }
            $converted_array[camel_case($old_key)] = $value;
        }
        return $converted_array;
    }

public static function convertToSnakeCase($array) {
        $converted_array = [];
        foreach ($array as $old_key => $value) {
            if (is_array($value)) {
                $value = static::convertToSnakeCase($value);
            } else if (is_object($value)) {
                if (method_exists($value, 'toArray')) {
                    $value = $value->toArray();
                } else {
                    $value = (array) $value;
                }
                $value = static::convertToSnakeCase($value);
            }
            $new_key = ltrim(strtolower(preg_replace('/[A-Z]/', '_$0', $old_key)), '_');
            $converted_array[$new_key] = $value;
        }
        return $converted_array;
    }


This will help for this.
