How does PHP handle following symlinks and what potential issues can arise from it?

When following symlinks in PHP, it is important to be cautious as it can potentially lead to security vulnerabilities. To prevent these issues, you can use the `realpath()` function in PHP to resolve the symlink path to its absolute path before using it in your code. 

$realPath = realpath('/path/to/symlink');
if($realPath){
    // Use $realPath in your code instead of the symlink path
} else {
    // Handle the case where the symlink cannot be resolved
}
