note 114047 added to language.references.spot

This is very useful in passing large arrays. If you do not pass the array by reference, you are creating another copy of the array in memory. <?php //Part 1 $x = 40; $y = $x; $z =& $x; echo '$x is ' . $x . '<br />'; //Show 40 echo '$y is ' . $y . '<br />'; //Show 40 echo '$z is ' . $z . '<br />'; //Show 40 //Part 2 $x = 50; echo '$x is ' . $x . '<br />'; //Show 50 echo '$y is ' . $y . '<br />'; //Show 40 echo '$z is ' . $z . '<br />'; //Show 50 ?> In part 2 value of $z will changes according to $x. ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/language.references.spot.php Edit -- https://master.php.net/note/edit/114047 Del: integrated -- https://master.php.net/note/delete/114047/integrated Del: useless -- https://master.php.net/note/delete/114047/useless Del: bad code -- https://master.php.net/note/delete/114047/bad+code Del: spam -- https://master.php.net/note/delete/114047/spam Del: non-english -- https://master.php.net/note/delete/114047/non-english Del: in docs -- https://master.php.net/note/delete/114047/in+docs Del: other reasons-- https://master.php.net/note/delete/114047 Reject -- https://master.php.net/note/reject/114047 Search -- https://master.php.net/manage/user-notes.php
