Php: namespace: access entities using aliases

One of the advantage of Php namespaces is, you can create aliases to the existing entities.

 

Let’s see it with an example.

 

dynamic_logger.php

<?php

namespace DynamicLogger;

class Logger{
    public function log(){
        echo "I am dynamic logger\n";
    }
}

?>

 

logger.php

<?php

namespace CustomLogger;

class Logger{
    public function log(){
        echo "I am custom logger\n";
    }
}

?>

 

Let’s create alias names to Logger classes present in DynamicLogger and CustomLogger namespaces.

 

use DynamicLogger\Logger as MyDynamicLogger;

use CustomLogger\Logger as MyCustomLogger;

 

Find the below working application.

 

aliases.php

#!/usr/bin/php
<?php
    include 'logger.php';
    include 'dynamic_logger.php';

    use DynamicLogger\Logger as MyDynamicLogger;
    use CustomLogger\Logger as MyCustomLogger;

    $dyn_logger = new MyDynamicLogger();
    $cust_logger = new MyCustomLogger;

    $dyn_logger->log();
    $cust_logger->log();
    
?>

Output

$./aliases.php 
I am dynamic logger
I am custom logger
