copied!<p>according to this answer -> <a href="https://stackoverflow.com/questions/348410/sort-an-array-based-on-another-array">Sort an Array by keys based on another Array?</a>, I use this function to get my another array sorted:</p> <pre><code>function sortArrayByArray($array,$orderArray) { $ordered = array(); foreach($orderArray as $key) { if(array_key_exists($key,$array)) { $ordered[$key] = $array[$key]; unset($array[$key]); } } return $ordered + $array; } </code></pre> <p>at first, I have my code like this and it works fine</p> <pre><code>$array1 = array("a","b","c"); $array2 = array("2","5","1"); $array3 = array("2","5","1"); rsort($array3); //5,2,1 for($i=0;$i<3;$i++){ $customer1[$array2[$i]] = $array1[$i]; } $properOrderedArray1 = sortArrayByArray($customer1, $array3); print_r($properOrderedArray1); </code></pre> <p>but when I use some logic math like multiply, it gets any errors like it said there is data type float</p> <pre><code>//multiply $a = 100000*100000; $b = 200000*200000; $c = 300000*300000; $array1 = array("a","b","c"); $array2 = array($a,$b,$c); $array3 = array($a,$b,$c); rsort($array3); //5,2,1 for($i=0;$i<3;$i++){ $customer1[$array2[$i]] = $array1[$i]; } $properOrderedArray1 = sortArrayByArray($customer1, $array3); print_r($properOrderedArray1); var_dump($array2); </code></pre> <p><strong>THE ERROR: Warning: array_key_exists(): The first argument should be either a string or an integer</strong></p> <p>so any solution for this problem? Thanks.</p>
