Bubble sort in PHP

Answer 1

Here it is:

$array_size = 250;

// If you use v4.2.0 or lower uncomment this

// srand((double)microtime()*1000000);

// Generate $array_size random numbers to be sorted.

for($x = 0; $x < $array_size; $x++)

$ran[$x] = rand(0, 500);

/* The bubble sort method. If you don't know how it works it's very

* simple, values are switched one at a time for each element. */

for($x = 0; $x < $array_size; $x++) {

for($y = 0; $y < $array_size; $y++) {

if($ran[$x] < $ran[$y]) {

$hold = $ran[$x];

$ran[$x] = $ran[$y];

$ran[$y] = $hold;

}

}

}

for($x = 0; $x < $array_size; $x++)

print $ran[$x] . "<br>";
