"usort funtion" usage help

[masood131]

Hi,
I am not getting the correct results on the number of calls to the function (compare). I placed a counter ($NumberofCalls) and it only shows one call to the function. Is that correct?

Also, I am not getting the correct result of the comparison for my arrays? It constantely gives me "1", which I don't think is the right answer.

Here is my code:

---

<?php
$products = array ( array ( 'TIR', 'Tires', 100 ),
array ( 'OIL', 'Oil', 10 ),
array ( 'SPK', 'Spark Plugs', 4 ) );

$NumberofCalls = 0;

function compare($x, $y)
{
$NumberofCalls++;
print ('This is the '.$NumberofCalls.' call to the function.<br />');

if ( $x[1] == $y[1] )
print ('Comparing '.$x[1].' to '.$y[1].' => '.( $x[1] == $y[1] ).'<br>');
else if ( $x[1] < $y[1] )
print ('Comparing '.$x[1].' to '.$y[1].' => '.( $x[1] < $y[1] ).'<br>');
else
print ('Comparing '.$x[1].' to '.$y[1].' => '.( $x[1] > $y[1] ).'<br>');
}

print ('-----------IN------------');
print ('<pre>');
print_r ($products);
print ('<pre>');

print ('-----------RESULT-------------<br />');
echo ( 'Function Result = '.usort ($products, 'compare') );
echo '<br />';

print ('<br />-----------OUT------------<br />');
print ('<pre>');
print_r ($products);
print ('<pre>');

?>

p.s. Can you tell me how I can put my code that I like for people in forum to see in a separate box?

To colorize your code and get it like a "quote" you use the BBCode tags:

[code=php]

As for the wrong output: Do you want to loop it? Because if you do, then a function() won't loop like a for() or while() will. And the $numberofcalls variable is right, since you're not looping and it's being incremented once from 0.

Also, where do you define the arrays of $x and $y? I'm not seeing it here.

Brett,

I figured it out. Thanks a million.
