What are the considerations when using PHP as a script engine in conjunction with batch files for data manipulation and processing?

When using PHP as a script engine in conjunction with batch files for data manipulation and processing, it is important to ensure that the PHP script can properly handle input and output from the batch file. This includes passing arguments to the PHP script from the batch file, as well as capturing and processing the output of the PHP script in the batch file.

<?php
// Read input arguments from batch file
$arg1 = $argv[1];
$arg2 = $argv[2];

// Perform data manipulation and processing
$result = $arg1 + $arg2;

// Output result to be captured by batch file
echo $result;
?>
