Preconditions and environment
📄 Description
Preconditions
- Magento Open Source: 2.4.9
- PHP Version: 8.5
- Environment: CLI and/or web execution (cron, currency formatting, or order flows)
- No custom modification in
Magento\Framework\Locale\Currency
🧩 Problem
When executing Magento code that triggers currency resolution (e.g. getCurrencySymbol()), PHP 8.5 emits a deprecation warning:
Deprecated: Using null as array offset is deprecated
The issue originates from Magento\Framework\Locale\Currency::getCurrency().
🔍 Affected Code
In vendor/magento/framework/Locale/Currency.php:
self::$_currencyCache[$this->_localeResolver->getLocale() ?? ''][$currency] = $currencyObject;
Steps to reproduce
🔁 Steps to Reproduce
- Install Magento Open Source 2.4.9
- Configure any store locale
- Run any operation that uses currency formatting, for example:
$this->currency->getCurrencySymbol();
- Observe PHP 8.5 deprecation warnings
📌 Impact
- PHP 8.5 deprecation warnings in CLI and web requests
- Affects all currency formatting operations
- Impacts logs, monitoring systems, and cron execution output
- Breaks clean execution in strict environments
📎 Notes
- Issue is reproducible only on PHP 8.5
- PHP 8.1–8.4 may not always show warnings depending on configuration
- Root cause is unsafe array key usage with nullable locale value
Expected result
No PHP warnings should be triggered.
🛠 Suggested Fix
Normalize locale before array usage:
$locale = (string) ($this->_localeResolver->getLocale() ?? '');
self::$_currencyCache[$locale][$currency] = $currencyObject;
And reuse $locale consistently throughout the method.
Locale value used as array key should always be safely normalized to a string.
Actual result
PHP emits warning:
Deprecated: Using null as array offset is deprecated
Triggered during currency cache storage when locale is null or not normalized.
