note 52463 deleted from function.unset by betz

Note Submitter: geoff at hoffmans dot net Reason: useless ---- If you want to remove a value from the middle of a linear array, you have to use the zero-based integer pointer to it, not the string you want to unset: <?php $a = array("a","b","c","d"); unset($a["b"]); // has no effect var_dump($a); ?> // prints array("a","b","c","d") <?php $a = array("a","b","c","d"); unset($a[1]); var_dump($a); ?> // prints array("a","c","d"); Conversely, if you have an associative array, unset requires the string key: <?php $a = array("a"=>"abc","b"=>"cbs","c"=>"nbc","d"=>"fox"); unset($a[1]); // has no effect var_dump($a); ?> // prints array("a"=>"abc","b"=>"cbs","c"=>"nbc","d"=>"fox") <?php $a = array("a"=>"abc","b"=>"cbs","c"=>"nbc","d"=>"fox"); unset($a["b"]); var_dump($a); ?> // prints array("a"=>"abc","c"=>"nbc","d"=>"fox")
