Hi list.
Basically, I'm still learning new things about php and I was wondering if
things inside an if statement get 'looked at' by a script if the condition
is false.
For example, would this mysql query get executed if $number = 0 ?
If ($number == 1) {
mysql_query($blah)
}
I know that's not

I would like to know how I can code the the following conditional
check if the $_GET['api'] does not exist, or is either set and has
no length or is set and is not an integer.
I am drawing a blank on the if statement to use

int strpos ( string haystack, string needle [, int offset])

Tipp: Do not use preg_match() if you only want to check if one string

will be faster.

This brings up a good point. Just exactly how much faster would one be

Make sure your benchmarks aren't bias:
- assignment takes time
- concating string takes time
You are right. I updated the script
not returning a false value...
But I'm still not getting the correct output on my page...
Any other ideas?

Alternatively Alexander,
take a look at the string functions eg strstr(), stristr(), and strpos() all
of which can be used to make a condition within the case() criteria.
