How can PHP projects be mistakenly flagged as potentially risky by antivirus programs?

PHP projects can be mistakenly flagged as potentially risky by antivirus programs due to the presence of certain functions or code patterns that are commonly associated with malicious activities, such as file manipulation or remote code execution. To avoid this, developers can ensure that their PHP code is well-documented, follows best practices, and does not contain any suspicious or obfuscated code. Additionally, using reputable code repositories and libraries can help mitigate the risk of false positives from antivirus software.

<?php

// Example of well-documented and clean PHP code
// This code snippet reads a file and outputs its content

$filename = "example.txt";

if (file_exists($filename)) {
    $content = file_get_contents($filename);
    echo $content;
} else {
    echo "File not found";
}

?>
