Need Help- Wont output

[doucettej3]

This code takes an array of random size nd with random integers and then finds the smallest value in the array. Im pretty sure the rest of the code is right up to the output. Any help would be awesome. heres the code

function smallest($passed_array)
{
//initialize the $smallest variable
$smallest = $random_max;
for($i = 0; $i <= $random_quantity; $i++)
{	if($smallest > $passed_array[$i])
{
$smallest = $passed_array[$i];
}
else
{
$smallest = $smallest;
}	
} 
print_r($random_numbers);
echo "<br>The Smallest number is $small";
}

where is

$random_max

and

$random_numbers

Defined, and used?

[doucettej3]

They are defined by the user in the input. This function is used in a switch with the function that actually creates the array

[DeanWhitehouse]

Does it print the array in the function?

$random_numbers

 

If not then try printing it outside and see if it is a problem somewhere else.

[doucettej3]

Yea it prints the array in the other function..i removed the print from this function ..i still get the same out put...the only thing missing from the output is $small.

[doucettej3]

this is the output :

 

Array ( [0] => 7 [1] => 7 [2] => 5 [3] => 13 [4] => 10 [5] => 6 [6] => 19 [7] => 12 [8] => 14 [9] => 12 [10] => 16 )

The Smallest number is

[DeanWhitehouse]

The var is called $smallest not $small ?

You don't need a function to get the smallest number in an array, just use rsort() and the smallest number is the $array[0]

 

Example:

<?php
$rand_array = range(1,100);
shuffle($rand_array);
echo 'Suffled Array: ' . implode(', ',$rand_array) . '<br>';	
$rand_array = array_slice($rand_array,rand(0,30),rand(50,100));
echo 'Sliced Array: ' . implode(', ',$rand_array) . '<br>';	
sort($rand_array);
echo 'Array contents: ' . implode(', ',$rand_array) . '<br>';
echo 'The smallest number is: ' . $rand_array[0];
?>
