If you wish to allow a function to modify its arguments, you must pass them by reference. see functions.html#FUNCTIONS.USER-DEFINED > <? > function alpha($a1) { so either define function alpha(&$a1) OR call with alpha(&0) > $a = $a1; > for ($i=$a;$i<10;$i++) { > $array1[$i] = $array1[$i] + 1; > } > > return; OR call like $myarray=alpha(0) then return $array1 (? not sure about the return) > }; > for ($i=0;$i<10;$i++) { > $array1[$i] = 0; > }; > > alpha(0); > ?> > > Hello world!!! > <? > for ($i=0;$i<10;$i++) { > echo "<br>The number is :".$array1[$i]; > } > ?> > > > cheers, Chris -------------------------------------------------------------------- -- C.Hayes Droevendaal 35 6708 PB Wageningen the Netherlands -- --------------------------------------------------------------------
