strcasecmp()

  • strcasecmp() is a PHP topic. In plain words you use it for a short strcasecmp example in a college portal page. Don’t start with a slogan — start with that picture.
  • Smallest example: the smallest strcasecmp example you can type. Type it, run it, and say what you see. If you can do that from memory, you know strcasecmp().
  • From the example next to this theory: strcasecmp(): scores array, print avg, then high marks.
  • Trap: only saying “strcasecmp” with no example. Fix that before you talk about advanced PHP.
  • Viva: what is strcasecmp()? Then show the smallest strcasecmp example you can type. Then name the trap.
