number checker

hello there,
I would like to create something so that if I give a number lets say (150)
the code checks from 0 until 150 and once it finds it then say "number found!"

nanharbison

this should work

<?PHP
$checkthisnumber = $_GET['thisnumber'];
 
$i=1;
while ($i < 151) 
{
	
 if ($i == $checkthisnumber) 
 	{
		echo "number found";
		break;
	}
$i++;
}
 
?>

ok I think I got it!

$checkthisnumber = '50';
 
$i=1;
while ($i < 151) 
{
        
 if ($i == $checkthisnumber) 
        {
                echo $checkthisnumber . ' number found';
                break;
        }
      			else
        				echo $i . ' not found<br>';
$i++;
}

like this

<?PHP
$checkthisnumber = $_GET['thisnumber'];
 
$i=1;
while ($i < 151) 
{
	
 if ($i == $checkthisnumber) 
 	{
		echo "number found, it is: ". $checkthisnumber;
	} else {
		echo $checkthisnumber." was not found ";
	}
$i++;
}
 
?>

oops, that was wrong

<?PHP
$checkthisnumber = $_GET['thisnumber'];
$checkthisnumber = 100;
$i=1;
while ($i < 151) 
{
	
 if ($i == $checkthisnumber) 
 	{
		echo "number found, it is: ". $checkthisnumber;
	} else {
		echo $i." was not found<br /> ";
	}
$i++;
}
 
?>

use the break statement if you want the loop to stop when the number is found.
