A: phpMyAdmin 4.7+ supports PHP 7.1 but may show a warning. Ignore it or upgrade phpMyAdmin manually.
Some extensions are disabled by default in older XAMPP. Enable these common ones:
In php.ini, uncomment:
extension=curl
extension=gd2
extension=mbstring
extension=mysqli
extension=openssl
extension=pdo_mysql
extension=zip
Need mcrypt? PHP 7.1 still supports it, but it’s deprecated. If your legacy app requires it:
extension=mcrypt
Note: mcrypt was removed in PHP 7.2. For future‑proofing, plan to migrate. xampp php 7.1.3
PHP 7.1.3 uses OpenSSL 1.0.2, which does not support TLS 1.3. If your legacy app tries to connect to a modern API (Stripe, GitHub, etc.), the connection may fail. Workaround: Force TLS 1.2 in your cURL options:
curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
After installation, you need to configure XAMPP to work with PHP 7.1.3. Here are some essential configuration steps: A : phpMyAdmin 4
Many older apps use mysql_* functions (deprecated in PHP 5.5 and removed in PHP 7.0). However, PHP 7.1.3 continues the removal—so you will need to refactor to mysqli or PDO.
Workaround for pure legacy horror: You can use a compatibility wrapper like mysql_to_mysqli.php, but the correct fix is rewriting queries. Some extensions are disabled by default in older XAMPP
When you install the specific XAMPP version that houses PHP 7.1.3 (historically XAMPP 7.1.3 / PHP 7.1.3), here is what you get out of the box:
Note: This version does not include sodium crypto library, nor does it support union types or iterable pseudo-types introduced later in 7.1.
