RE: [PHP] Array Problem

> What is the best way to delete an element from an array? > I tried using unset(), and it didn't work. unset works with arrary elements, but it must be a global variable and not passed in. Try the code below to see the results. <?php // deletes an element of global array function deleteGlobal() { global $animals; echo "<br>in deleteGlobal()-Spot<br>\n"; unset ($animals["Spot"]); foreach ($animals as $key => $value) { echo "$key: $value<br>\n"; } } // deletes an element in local array only function deleteElement($annArr) { echo "<br>in deleteElement()-Felix<br>\n"; unset ($annArr["Felix"]); foreach ($annArr as $key => $value) { echo "$key: $value<br>\n"; } } // $animals = array("Kitty"=>"cat", "Max"=>"dog", "Spot"=>"Dog", "Felix"=>"cat","Morris"=>"cat"); echo "Initial array<br>\n"; foreach ($animals as $key => $value) { echo "$key: $value<br>\n"; } deleteGlobal(); echo "<br>after deleteGlobal()<br>\n"; foreach ($animals as $key => $value) { echo "$key: $value<br>\n"; } deleteElement($animals); echo "<br>after deleteElement()<br>\n"; foreach ($animals as $key => $value) { echo "$key: $value<br>\n"; } echo "<br>After unset()-Morris<br>\n"; unset ($animals["Morris"]); foreach ($animals as $key => $value) { echo "$key: $value<br>\n"; } ?>
