fwrite() expects parameter 1 to be resource and fclose() expects parameter 1 to be resource

Question

private function WriteFile($file,$mode,$content){
    $handle = fopen($file, $mode);
    fwrite($handle, $content);
    fclose($handle);
}

this is my code and giving me the error

fclose() expects parameter 1 to be resource, boolean given in and fwrite() expects parameter 1 to be resource, boolean given in directory

Use the debugger. Is parameter 1 a resource? (Also, what language is this?) — Raymond Chen, Nov 29 '17 at 14:57
Please check the `error_reporting` and `display_errors` directives. Otherwise, you're coding in the dark. — Álvaro González, Nov 29 '17 at 15:14
@MamunurRashid The error message is clear enough. Take a look the answer I made. — ADreNaLiNe-DJ, Nov 29 '17 at 15:16
It really looks like you're recreating the `file_put_contents` wheel here anyway. — Don't Panic, Nov 29 '17 at 15:20

This is because fopen fails to open your file: the error message indicates that a boolean is given instead of a resource.

From PHP documentation:

Returns a file pointer resource on success, or FALSE on error.

You should check the value of $handle.

$handle = fopen($file, $mode);
if(is_resource($handle)) {
    fwrite($handle, $content);
    fclose($handle);
} else {
    // Handle error if needed
}

Checking that it isn't false, as in `if ($handle) {/*...*/}`, is enough. – Álvaro González Dec 02 '17 at 08:57
