Question

how can i get the “filesize” from a string in php?

I put the string in a mysql database as a blob and i need to store the size of the blob. My solution was to create a temp file and put the string into the temp file. now i can get the filesize from the “string”. but that solution is not good…

greetings

It depends. If you have mbstring function overloading enabled, the only call that will work will be mb_strlen($string, '8bit');. If it’s not enabled, strlen($string) will work fine as well.

So, you can handle both cases like this:

if (function_exists('mb_strlen')) {
    $size = mb_strlen($string, '8bit');
} else {
    $size = strlen($string);
}
