[RESOLVED] conditional processing

[themanwhowas]

imagine i have the following code

if($var == 12)
{
echo 'blah';
echo 'blah';
echo 'blah';
echo 'blah';
echo 'blah';
echo 'blah';
echo 'blah';
echo 'blah';
echo 'blah';
echo 'blah';
}
else
{
echo 'blah';
}

lets imagine that if $var is 12 the page takes 5 seconds to load. if $var isnt 12 will the page still take 5 seconds to load? I need to know if the unused code in conditionals are still processed, or maybe processed before the conditionals.
thanks

All of the code is parsed and compiled the same regardless of what value $var will be (probably measured in milliseconds), but then when the code is executed, the commands within the if block will not be executed at all if $var != 12. So, if each echo 'blah'; takes 0.5 seconds to execute, the when $var == 12 it will take 5 seconds plus the time it takes to parse/compile the script, while if $var != 12 it will take 0.5 seconds plus the time it takes to parse/compile the script.
