Question

THIS WORKS:

1 $number  = 2;
2 $allofit = simplexml_load_file("thexmlfile.xml");
3 $thebook = $allofit -> booklist[$number] -> abook;
4 echo $thebook;

THIS FOLLOWING DOES NOT WORK:
But if I want to read $number from a from with method GET I set

 6 $number=$_GET[thenumber];   // $number=2 from the form//
 7 echo $number;              // and properly shows $number=2 --*/
 8 $allofit = simplexml_load_file("thexmlfile.xml");
 9 $thebook = $allofit -> booklist[$number] -> abook;
 10 echo $thebook;

The echo on line 10 reports nothing (no error, just blank space in the html) even though I can successfully echo $number in line 7… so its being set, but just not picked up in line 9.. although the equivalent in line 3 works (!).

Any ideas folks?

Thanks in advance

Answer 1

$number=$_GET[thenumber];

At this stage $number is a string.

Do you need to coerce it into an integer? Probably with intval? http://php.net/manual/en/function.intval.php
