What potential issue is the forum user facing with the variable "$myline" in the code?

The potential issue the forum user is facing with the variable "$myline" in the code is that it is being used outside the loop where it is defined. This can lead to errors or unexpected behavior as the variable may not be initialized or may hold incorrect values when accessed outside its scope. To solve this issue, the variable "$myline" should be defined within the loop where it is being used.

$myfile = fopen("example.txt", "r") or die("Unable to open file!");

// Read the file line by line
while(!feof($myfile)) {
    $myline = fgets($myfile);
    // Process $myline here
}

fclose($myfile);
