Are there any potential performance issues with using the file() function in PHP to read HTML files?

Using the file() function in PHP to read HTML files can potentially lead to performance issues when dealing with large files or a high volume of file reads. To address this, it is recommended to use more efficient methods like file_get_contents() for reading the contents of a file into a string variable. 

// Read the contents of an HTML file using file_get_contents()
$htmlContent = file_get_contents('example.html');

// Output the HTML content
echo $htmlContent;
