in my country now theres tons of IT school teaching this language,dunno about ur place
But you could buy some ebooks and learn it urself,PHP is a scripting language,its extremly easy to learn,everyone with a basic HTML understanding could get rid of it
And if you want a PHP course,check out VTC`s frequency training or Lynda's training,they got CD-ROM with videos that teaching you PHP very carefully,but it's price is very high(VTC`s disk is about 99 bucks ek ek ><,Lyndas are aroun 30 to 50)
