note 71768 deleted from ref.array by nlopess

Note Submitter: xixona at voila dot fr ---- I was inspired by zspencer at zacharyspencer dot com into making my own set function, but I wanted it to return the value if found and false otherwise. I also based myself on his algorithm : <? $tab=array(); $tab['a']='lala'; $tab['b']='blabla'; $tab['c']='nono'; echo set($tab, 'b'); // outputs blabla echo next($tab); //outputs nono function set(&$tab, $key){ reset($tab); while ( ($key != key($tab)) && next($tab) ){} return current($tab); } /*The loop uses the fact that && only evaluates the second term if the first is true. Therefore, if the first key is the one we seek, the "next" command won't be evaluated. "next($tab)" also allows the loop to check every element while serving as an exit condition. (end($tab); next($tab); returns false)*/ ?>
