What potential issues can arise when using the file_get_contents function in PHP to read external content?

One potential issue when using `file_get_contents` to read external content is that it may not handle errors or timeouts gracefully, leading to potential security vulnerabilities or application instability. To solve this, you can use a combination of `stream_context_create` to set timeout options and error handling using `try-catch` blocks. 

try {
    $context = stream_context_create([
        'http' => [
            'timeout' => 10 // Set timeout to 10 seconds
        ]
    ]);

    $content = file_get_contents('http://example.com', false, $context);
    
    // Process the content here
} catch (Exception $e) {
    echo "Error fetching content: " . $e->getMessage();
}
