Does anyone know how the PHP Interpreter pulls switch/case statements together? Does it emulate a C compiler and, for larger case sets, build a huge if/else cascade? Does it do this always? Is there any way to know when it builds a jump table (like a s/c is supposed to)? I've got a slow script (it's eating ~85% of execution time) that I can't work around and one of the slower parts is a switch case (which is slightly faster than manually building an if/else cascade) and was wondering if anyone had any performance tips for cases like these.
