Dear documentation team, I have tried several times to submit a note to the documentation of the php manual. This, however, has been impossible. Here is my note: +--- NOTE BEGINS HERE -------------------------------------- Sergio Santana: [EMAIL PROTECTED] Sometimes we need functions for building or modifying arrays whose elements are to be references to other variables (arrays or objects for instance). In this example, I wrote two functions 'tst' and 'tst1' that perform this task. Note how the functions are written, and how they are used. <? function tst(&$arr, $r) { // The argument '$arr' is declared to be passed by reference, // but '$r' is not; // however, in the function's body, we use a reference to // the '$r' argument array_push($arr, &$r); // Alternatively, this also could be $arr[] = &$r (in this case) } $arr0 = array(); // an empty array $arr1 = array(1,2,3); // the array to be referenced in $arr0 // Note how we call the function: tst($arr0, &$arr1); // We are passing a reference to '$arr1' in the call ! print_r($arr0); // Contains just the reference to $arr1 array_push($arr0, 5); // we add another element to $arr0 array_push($arr1, 18); // we add another element to $arr1 as well print_r($arr1); print_r($arr0); // Changes in $arr1 are reflected in $arr0 // ----------------------------------------- // A simpler way to do this: function tst1(&$arr, &$r) { // Both arguments '$arr' and '$r" are declared to be passed by // reference, // again, in the function's body, we use a reference to // the '$r' argument array_push($arr, &$r); // Alternatively, this also could be $arr[] = &$r (in this case) } $arr0 = array(); // an empty array $arr1 = array(1,2,3); // the array to be referenced in $arr0 // Note how we call the function: tst1($arr0, $arr1); // 'tst1' understands '$r' is a reference to '$arr1' echo "-------- 2nd. alternative ------------ <br>\n"; print_r($arr0); // Contains just the reference to $arr1 array_push($arr0, 5); // we add another element to $arr0 array_push($arr1, 18); print_r($arr1); print_r($arr0); // Changes in $arr1 are reflected in $arr0 ?> // This outputs: // X-Powered-By: PHP/4.1.2 // Content-type: text/html // // Array // ( // [0] => Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // ) // // ) // Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // [3] => 18 // ) // Array // ( // [0] => Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // [3] => 18 // ) // // [1] => 5 // ) // -------- 2nd. alternative ------------ // Array // ( // [0] => Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // ) // // ) // Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // [3] => 18 // ) // Array // ( // [0] => Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // [3] => 18 // ) // // [1] => 5 // ) In both cases we get the same result. I hope this is somehow useful Sergio. +--- NOTE ENDS HERE -------------------------------------- And, here is the notification I receive each time: "There was an internal error processing your
submission. Please try to submit again later."
