Can I write to a text file within a php function?

[Dvae56]

I'm trying to include a routine to catch an error but it doesn't seem to write to a text file within a function. just using the following simple code, even if I simply try to write a letter it doesn't work

 

if ($http_status == 200) {
        return $response;

    } else {


$myfile = fopen("ErrorData.txt", "a+") or die("Unable to open file!");

$txt =  date("H:i:sa d-m-Y")." / Error data- / ".json_encode($response)."\r\n";
fwrite($myfile, $txt);
fclose($myfile);


}

 Where's the function?

Are you getting any errors? Did you check the server error log? Or is PHP set to display errors?

Side note: file_put_contents() does all the work of fopen(), fwrite() and fclose(). More information can be found here:
