hey guys, Im afraid I will be posting a lot of questions as I slowly work my way through these tutorials... simple question though.

it says that it can convert this string into an integer what I dont understand is I thoguht integers could only be numbers... so how can he change the $mystring into an integer?

<?php
  $mystring = "wombat";
  $myinteger = (integer)$mystring
?>

From what I understand:

It will keep it an integer (number) until there is a letter. After the letter, it will not echo anything. If there are no numbers, it will show a 0

[code]<?php
  $mystring = "1c2234234a3";
  $myinteger = (integer)$mystring;
echo $myinteger;
?>[/code]
Will output: 1

[code]<?php
  $mystring = "12234234a3";
  $myinteger = (integer)$mystring;
echo $myinteger;
?>[/code]
Will output: 12234234

[code]<?php
  $mystring = "abc";
  $myinteger = (integer)$mystring;
echo $myinteger;
?>[/code]
Will output: 0

see thats what Im thinking too... but then why would he use an example which he cant really turn into an integer for this part in the book?

He is just giving an example. However not a very clear example.
