Question

I have string

$text = "this is my text";

and i want to know the size(byte), not text length.

so i tried to use

filesize();

but i get Error

Warning: filesize(): stat failed for this is my text

and if i tried to use

mb_strlen()

it only count the text lenght, not the size.

How to know the text size ? i want the result something like “1024 bytes”

Thanks

Answer 1

in your case byte length is the same as string length. use strlen like so:

$length = strlen($text);

or if you want to be complicated use:

file_put_contents('myfile.txt', $text);
$length = filesize('myfile.txt');
unlink('myfile.txt');
