[SOLVED] php math error for array

[doucettej3]

i am using a function that finds the smallest value in an array. The array is of random size and has random values. The size is input by the user and the range of the values is input by the user. The output is givin me this :

Array ( [0] => 15 [1] => 3 [2] => 19 [3] => 13 [4] => 9 [5] => 15 [6] => 19 [7] => 6 [8] => 18 [9] => 5 [10] => 5 )

The Smallest number is 1

 

one obviously isnt the smallest number because its not even in the array. Any help with the code would be great. Also it gets the array thru a switch statement with a function that creates the array.

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

Try:

function small_array($passed_array, $random_max, $random_quantity)
{
//initialize the $small variable
$small = $random_max;
for($i = 0; $i < $random_quantity; $i++)
{	if($small >= $passed_array[$i])
{
$small = $passed_array[$i];
}

} 
echo "<br>The Smallest number is $small";
}

 

for beginning.

 

BTW: you can use min() to get smallest value from an array.
