What potential issues could arise when using file_get_contents() in PHP to read a JSON file?

One potential issue that could arise when using file_get_contents() in PHP to read a JSON file is that it may not handle errors or exceptions well, leading to unexpected behavior or crashes if the file is not found or inaccessible. To solve this, you can use error handling techniques such as try-catch blocks to handle any potential errors that may occur during the file reading process. 

<?php
$file = 'example.json';

try {
    $json = file_get_contents($file);
    if($json === false){
        throw new Exception("Error reading file");
    }
    
    // Process the JSON data here

} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}
?>
