note 95316 deleted from function.end by danbrown

Note Submitter: alexander at example dot com ---- I want to unite some previous notes. I needed to see if it was the last element of array in foreach and there is no in-built function for it. To y dot vecchi at gmail dot com: Your code will not work properly if a few elements of array have the same value with the last one. All these will be counted as last elements. Here goes my code: <?php //Warning: we do NOT get the reference to actual key this way function lastkey($myarray = 1) { //if we did not send argument, it goes as not array argument (integer here) //checking if (!is_array($myarray)) return null; //no need to check if the array is empty - we shall get false in this case //so we can know if it was empty array (result is false) or not array (result is null) $allmykeys = array_keys($myarray); return end($allmykeys); //note: or use code mentioned by jasper at jtey dot com //it seems alright except it does not check array //so just add checking at the beginning of his function if you like it } $somearray = array(1 => 'one', 'two', 'three' => 'three', '3' => 'three'); foreach ($somearray as $key => $value) { if($key == lastkey($somearray)) echo "Last key is ".$key." and last value is ".$value;//it shows key 3, not 'three' } //no errors here echo lastkey()===null;//1 echo lastkey(null)===null;//1 echo lastkey(12)===null;//1 echo lastkey(array())===false;//1 ?>
