How can Perl scripts be utilized to capture screenshots of web pages in a PHP environment?

To capture screenshots of web pages in a PHP environment using Perl scripts, you can utilize the `exec()` function in PHP to call a Perl script that uses a library like `WWW::Mechanize::Firefox` or `WWW::Mechanize::Chrome` to capture the screenshot.

```php
<?php

$url = 'https://www.example.com';
$outputFile = 'screenshot.png';

$perlScript = 'perl capture_screenshot.pl ' . $url . ' ' . $outputFile;
exec($perlScript);

?>
``` 

The above PHP code snippet calls a Perl script named `capture_screenshot.pl` with the URL of the web page to capture and the output file name for the screenshot. The Perl script would use a module like `WWW::Mechanize::Firefox` or `WWW::Mechanize::Chrome` to open the webpage, capture the screenshot, and save it to the specified output file.
