filesize(): stat failed for http://localhost/jobportal/public/uploads/document/1.doc and

Answer 1

As you can see here http://php.net/manual/en/function.filesize.php :

As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to Supported Protocols and Wrappers to determine which wrappers support stat() family of functionality.

and if you will go to this link http://www.php.net/manual/en/wrappers.http.php , you will see that Supports stat() is "NO". So you can't use http links with filesize function. If this is local file just use absolute or relevant path of the file like '/path/to/my/file', if this is remote file (not sure but) I think it should be downloaded first with curl and curl_getinfo function to read Content-Length http property

Answer 2

That filesize(): stat failed for http://localhost/jobportal/public/uploads/document/1.doc means: you are trying to get the filesize of an URL which isn't applicable.

You need to read from the stream in chunks until end and check how many data actually has been submitted.

if($ext == 'doc'){
    if(file_exists($filename) ) {        
    if(($fh = fopen($filename, 'r')) !== false ) {
    $headers = fread($fh, 0xA00);
    $n1 = ( ord($headers[0x21C]) - 1 );
    $n2 = ( ( ord($headers[0x21D]) - 8 ) * 256 );
    $n3 = ( ( ord($headers[0x21E]) * 256 ) * 256 );
    $n4 = ( ( ( ord($headers[0x21F]) * 256 ) * 256 ) * 256 );
    $textLength = ($n1 + $n2 + $n3 + $n4);
    $content_of_file1 = fread($fh, $textLength);
    $content_of_file = strtolower($content_of_file1);

    }
}

}
