In other words, if we have the index in $var and, by one reason or another, make a reference to it (like $ndx2 =& $ndx) we no longer can use it to access a SplFixedArray. (We would have to copy $ndx, or $ndx2, to a temp normal variable and use it instead.) Test script: --------------- <?php $list = new SplFixedArray(10); $ndx = 1; $ndx2 =& $ndx; $list[$ndx] = 123; // This throws an exception; $list[$ndx2] = 123; // as does this, to. echo 'ok'; Expected result: ---------------- It should just print "ok". Actual result: -------------- "Uncaught RuntimeException: Index invalid or out of range" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70853&edit=1
