How can unexpected T_VARIABLE errors be resolved when using fwrite in PHP to write to a file?

To resolve unexpected T_VARIABLE errors when using fwrite in PHP to write to a file, make sure that the variable you are trying to write is properly concatenated or enclosed within double quotes. This error often occurs when a variable is not properly concatenated within the string being written to the file.

$file = fopen("example.txt", "w");
$name = "John";
fwrite($file, "Hello, $name"); // Correctly concatenate the variable within double quotes
fclose($file);
