How to retrieve the content of a txt file in php?

You can use the file_get_contents() function in PHP to retrieve the contents of a text file. Here is the specific code:

$file = 'example.txt';
$content = file_get_contents($file);

echo $content;

The code above will store the contents of the example.txt file in the $content variable and then print it out. Make sure the file path is correct and has the necessary read permissions.
