the while function knows to just go through those and fills in array numbers accordingly?
The while function has nothing to do with it. Using the syntax $array[] simply adds an element onto the _end_ of the array and PHP picks the next logical, numerical index.
OK thanks guys, I got the missing curly brace & some other messes.
So when assigning values to an array inside a loop, it knows to advance to the next but then if I want to print those out at the same time, it's complaining
while ($file = readdir($fh)){
if (strstr ($file, '.jpg')){
$pictures[] = $file;
#print $pictures[]; #Fatal error: Cannot use [] for reading
}
var_dump ($pictures[]); #Fatal error: Cannot use [] for reading
}This one works but complains about Undefined variable: pictures NULL array (but it dumps the contents of $pictures[]:
while ($file = readdir($fh)){
if (strstr ($file, '.jpg')){
$pictures[] = $file;
}
var_dump ($pictures);
