 As a part of this effort, we'll be making the following changes to Azure Cache for Redis:
 
-* **Phase 1:** We'll configure the default minimum TLS version to be 1.2 for newly created cache instances.  Existing cache instances won't be updated at this point.  You'll be allowed to [change the minimum TLS version](cache-configure.md#access-ports) back to 1.0 or 1.1 for backward compatibility, if needed.  This change can be done through the Azure portal or other management APIs.

 * **Phase 2:** We'll stop supporting TLS versions 1.0 and 1.1. After this change, your application will be required to use TLS 1.2 or later to communicate with your cache.
 
 Additionally, as a part of this change, we'll be removing support for older, insecure cypher suites.  Our supported cypher suites will be restricted to the following when the cache is configured with a minimum TLS version of 1.2.

 ### PHP
 
-Predis on PHP 7 won't work because PHP 7 supports only TLS 1.0. On PHP 7.2.1 or earlier, Predis uses TLS 1.0 or 1.1 by default. You can specify TLS 1.2 when you create the client instance:
-
-``` PHP
-$redis=newPredis\Client([
-    'scheme'=>'tls',
-    'host'=>'host',
-    'port'=>6380,
-    'password'=>'password',
-    'ssl'=>[
-        'crypto_type'=>STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT,
-    ],
-]);
-```

-On PHP 7.3 or above, Predis uses the latest TLS version.
+#### Predis
+ 
+* Versions earlier than PHP 7: Predis supports only TLS 1.0. These versions don't work with TLS 1.2; you must upgrade to use TLS 1.2.
+ 
+* PHP 7.0 to PHP 7.2.1: Predis uses only TLS 1.0 or 1.1 by default. You can use the following workaround to use TLS 1.2. Specify TLS 1.2 when you create the client instance:
+
+  ``` PHP
+  $redis=newPredis\Client([
+      'scheme'=>'tls',
+      'host'=>'host',
+      'port'=>6380,
+      'password'=>'password',
+      'ssl'=>[
+          'crypto_type'=>STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT,
+      ],
+  ]);
+  ```
+
+* PHP 7.3 and later versions: Predis uses the latest TLS version.
+
+#### PhpRedis
 
 PhpRedis doesn't support TLS on any PHP version.
