Re: arrays

> Can arrays be passed to functions just like a simple variable? yes, no difference. You can pass every variable to a function, you can pass constants or your values directly. You have to use a variable if a function requires passing by reference or if you want to pass by refernce, because only variables can take the value back. > Can arrays be passed as values in hidden form fields just like a > simple variable? yes, but differently. either you serialize the array, send it urlencoded to the page and unserialze it there: //page1.php: <?php $array = array(1,2,3,4,5); $array = urlencode(serialize($array)); ?> <a href="page2.php?array=<?php echo $array; ?>">Page2</a> //or input field: <input type="hidden" name="array" value="<?php echo $array; ?>"> //page2.php <?php $array = unserialize($array); print_r($array); ?> or you can appen urls like this, no serialization or sth needed then both pages: numerical indexed arrays: <a href="page2.php?array[]=1&array[]=2&array[]=3&array[]=4&array[]=5">Page2</a> or <a href="page2.php?array[0]=1&array[1]=2&array[2]=3&array[3]=4&array[4]=5">Page 2</a> string indexed arrays: <a href="page2.php?array[test1]=1&array[test2]=2&array[test3]=3&array[test4]=4& array[test5]=5">Page2</a> or with forms: numerical indexed arrays: <input type="hidden" name="array[]" value="1"> <input type="hidden" name="array[]" value="2"> <input type="hidden" name="array[]" value="3"> <input type="hidden" name="array[]" value="4"> <input type="hidden" name="array[]" value="5"> or <input type="hidden" name="array[0]" value="1"> <input type="hidden" name="array[2]" value="2"> <input type="hidden" name="array[3]" value="3"> <input type="hidden" name="array[4]" value="4"> <input type="hidden" name="array[5]" value="5"> string indexed arrays: <input type="hidden" name="array[test1]" value="1"> <input type="hidden" name="array[test2]" value="2"> <input type="hidden" name="array[test3]" value="3"> <input type="hidden" name="array[test4]" value="4"> <input type="hidden" name="array[test5]" value="5"> Michael "Michael Hall" <olc@ninti.com> schrieb im Newsbeitrag news:Pine.LNX.4.21.0205262226310.740-100000@localhost.localdomain... > > A couple of simple ones here ... the usual references don't appear to give > a straightforward answer on these: > > Can arrays be passed to functions just like a simple variable? > > Can arrays be passed as values in hidden form fields just like a > simple variable? > > I've been playing around with these and getting inconsistent results. > I've been trying things like serialize and urlencode, but still haven't > worked out a straightforward 'rule' or policy. > > Can someone throw some light on this? > > TIA > Michael >
