In the following snippet of code the numbers 12345 and 67890 are multiplied together, returning a result of 838102050, which is then placed in the variable $number. Automatic conversion from a number to a string <?php $number = 12345 * 67890; echo substr($number, 3, 1); ?> At the point of the assignment, $number is a numeric variable. ...

"</pre>"; $headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; // Email the error to someone... error_log($email, 1, 'you@youremail.com', $headers); // Make sure that you decide how to respond to errors (on the user's side) // Either ...
