count in for loop

[admin]

One simple optimization that most people miss is not using count($var) as a condition of for loops.

PHP Code:

// Wrong
for ($i = 0; $i < count($Results); $i++)
{
// Do Something
} 


PHP Code:

// Correct
$ResultCount = count($Results);
for ($i = 0; $i < $ResultCount; $i++)
{
// Do Something
} 


It’s very simple, and now you’re not counting the size of the stack every time you process the loop.
