Redis PHP connection operation, redisphp connection
Installation
To use Redis in a PHP program, you first need to ensure that the PHP driver for Redis and the PHP installation are set up on the machine. You can view the PHP tutorial to teach you how to install PHP on your machine. Now, let’s take a look at setting up the PHP driver for Redis.
You need to download phpredis from the github repository: https://github.com/nicolasff/phpredis. After the download is complete, unzip the file to the phpredis directory. To install this extension on Ubuntu, use the command shown in the figure below to install it.
<span class="pln"> cd phpredis sudo phpize sudo ./configure sudo make sudo make install </span>
Now, copy and paste the contents of the “modules” folder into the PHP extensions directory and add the following lines in php.ini.
<span class="pln"> extension = redis.so </span>
Now Redis and PHP installation is complete.
Connect to Redis server
<span class="pln">
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
//check whether server is running or not
echo "Server is running: " . $redis->ping();
?>
</span>
When the program is executed, the following results will be produced:
<span class="pln"> Connection to server sucessfully Server is running: PONG </span>
Redis PHP string example
<span class="pln">
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
//set the data in redis string
$redis->set("tutorial-name", "Redis tutorial");
// Get the stored data and print it
echo "Stored string in redis:: " . $redis.get("tutorial-name");
?>
</span>
When the program is executed, the following results will be produced:
<span class="pln"> Connection to server sucessfully Stored string in redis:: Redis tutorial </span>
Redis PHP list example
<span class="pln">
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
//store data in redis list
$redis->lpush("tutorial-list", "Redis");
$redis->lpush("tutorial-list", "Mongodb");
$redis->lpush("tutorial-list", "Mysql");
// Get the stored data and print it
$arList = $redis->lrange("tutorial-list", 0 ,5);
echo "Stored string in redis:: "
print_r($arList);
?>
</span>
When the program is executed, the following results will be produced:
<span class="pln"> Connection to server sucessfully Stored string in redis:: Redis Mongodb Mysql </span>
Redis PHP key example
<span class="pln">
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
// Get the stored keys and print it
$arList = $redis->keys("*");
echo "Stored keys in redis:: "
print_r($arList);
?>
</span>
When the program is executed, the following results will be produced:
<span class="pln"> Connection to server sucessfully Stored string in redis:: tutorial-name tutorial-list</span>

How to handle File Uploads securely in PHP?
Jul 08, 2025 am 02:37 AM
To safely handle PHP file uploads, you need to verify the source and type, control the file name and path, set server restrictions, and process media files twice. 1. Verify the upload source to prevent CSRF through token and detect the real MIME type through finfo_file using whitelist control; 2. Rename the file to a random string and determine the extension to store it in a non-Web directory according to the detection type; 3. PHP configuration limits the upload size and temporary directory Nginx/Apache prohibits access to the upload directory; 4. The GD library resaves the pictures to clear potential malicious data.

PHP find the position of the last occurrence of a substring
Jul 09, 2025 am 02:49 AM
The most direct way to find the last occurrence of a substring in PHP is to use the strrpos() function. 1. Use strrpos() function to directly obtain the index of the last occurrence of the substring in the main string. If it is not found, it returns false. The syntax is strrpos($haystack,$needle,$offset=0). 2. If you need to ignore case, you can use the strripos() function to implement case-insensitive search. 3. For multi-byte characters such as Chinese, the mb_strrpos() function in the mbstring extension should be used to ensure that the character position is returned instead of the byte position. 4. Note that strrpos() returns f
PHP header location ajax call not working
Jul 10, 2025 pm 01:46 PM
The reason why header('Location:...') in AJAX request is invalid is that the browser will not automatically perform page redirects. Because in the AJAX request, the 302 status code and Location header information returned by the server will be processed as response data, rather than triggering the jump behavior. Solutions are: 1. Return JSON data in PHP and include a jump URL; 2. Check the redirect field in the front-end AJAX callback and jump manually with window.location.href; 3. Ensure that the PHP output is only JSON to avoid parsing failure; 4. To deal with cross-domain problems, you need to set appropriate CORS headers; 5. To prevent cache interference, you can add a timestamp or set cache:f

How do I check if Composer is installed correctly?
Jul 07, 2025 am 12:12 AM
To check whether Composer is installed correctly, first run the composer--version command to view the version information. If the version number is displayed, it means that it is installed. Secondly, use the composerdiagnose command to detect configuration problems and ensure that the environment variables and permissions are normal. Finally, try to verify the functional integrity through the composerrequiremonolog/monolog installation package. If the vendor directory is successfully created and the dependency is downloaded, it means that Composer is fully available. If the above steps fail, you may need to check whether PHP has been installed globally or adjusted system path settings.
Windows automatic repair loop fix
Jul 07, 2025 am 01:31 AM
Use the installation media to enter the recovery environment; 2. Run the bootrec command to repair the boot records; 3. Check for disk errors and repair system files; 4. Disable automatic repair as a temporary means. The Windows automatic repair loop is usually caused by system files corruption, hard disk errors or boot configuration abnormalities. The solution includes troubleshooting by installing the USB flash drive into the recovery environment, using bootrec to repair MBR and BCD, running chkdsk and DISM/sfc to repair disk and system files. If it is invalid, the automatic repair function can be temporarily disabled, but the root cause needs to be checked later to ensure that the hard disk and boot structure are normal.
How to prevent session hijacking in PHP?
Jul 11, 2025 am 03:15 AM
To prevent session hijacking in PHP, the following measures need to be taken: 1. Use HTTPS to encrypt the transmission and set session.cookie_secure=1 in php.ini; 2. Set the security cookie attributes, including httponly, secure and samesite; 3. Call session_regenerate_id(true) when the user logs in or permissions change to change to change the SessionID; 4. Limit the Session life cycle, reasonably configure gc_maxlifetime and record the user's activity time; 5. Prohibit exposing the SessionID to the URL, and set session.use_only
