Of course you need to give the variable $someNumber a value.

CODE


$number = `echo $someNumber | /var/www/TestScanf`;
//$number = `/var/www/TestScanf`;
echo 'number in php<br />';

echo  $number;

OUTPUT


Notice: Undefined variable: someNumber in /var/www/Scanf.php on line 36
number in php
Enter your Number 0

To input an integer into a PHP script, with the number being generated by an external C program.
