PHP ApiGate_Register::keyExists Examples

Example #1

File: ApiGate_Register.class.php Project: Tjorriemorrie/app

 /**
  * Returns a valid (and available API key) to be used in the system.
  *
  * Border-line irrelevant note: There is a potential race-condition that you
  * could get this key and store it to the database at approximately the same time as someone who generated the same key
  * (prior to you storing) but that should be approximately a one in 16^40 chance (unless you seed the PRNG with
  * a timestamp or something patently wrong like that) so I'm not going to spend time preventing that at the moment.
  *
  * Takes NO parameters and is static so that the generation isn't affected by state at all... the 
  * generation is supposed to be random and using any state from the user or registration object would
  * just reduce the entropy of the pseudo-random number generator.
