How can backslashes in Windows paths be converted to slashes in PHP?

Backslashes in Windows paths can be converted to slashes in PHP by using the str_replace() function to replace backslashes with forward slashes. This is necessary when working with file paths in PHP, as backslashes are used as escape characters and can cause issues when trying to access files or directories. By converting backslashes to slashes, you ensure that your file paths are correctly formatted and compatible with PHP functions.

$path = "C:\\Users\\User\\Documents\\file.txt";
$path = str_replace("\\", "/", $path);
echo $path;
