Sort a php array returning new array

阅读更多关于 Sort a php array returning new array

问题 I am looking for a reliable standard method to sort an array, returning the sorted ( associative ) array, as return value . All the PHP.net functions I have read about return BOOLEAN value, or 0-1. The method I need would be something like: $some_mixed_array = array( 998, 6, 430 ); function custom_sort( $array ) { // Sort it // return sorted array } custom_sort( $some_mixed_array ); // returning: array( 6, 430, 998 ) No need to handle strings, just INT-s. 回答1: Would you be able to do this?

PHP: How to populate a directory structure in an array

阅读更多关于 PHP: How to populate a directory structure in an array

I am developing an admin panel that shows the directory structure of a specific location on server. I have got a recursive php function that iterates through every file and folder there is. What I can't figure out is how can I store this directory structure in a php associative array like this: array[foldername1][0]=file; // if the foldername1 contains a file array[foldername1][foldername2][0]=file //if foldername1 contains another folder(foldername2) along with the file. The rule i am trying to follow is; a folder should always be a key and file should always be at an index like this: array

PHP: Using spaces in associative array indices

阅读更多关于 PHP: Using spaces in associative array indices

问题 Is this bad practice/can cause problems? $_SESSION['stuff to keep'] As opposed to calling str_replace() on the indices. 回答1: This is bad practice, but not because of the space. // file foo.php $_SESSION['stuff to keep'] = 42; // file bar.php if ($_SESSION['stufft o keep'] == 42) frobnicate(); Here, your code is silently misbehaving, and the bug can take a while to be found. Good practice is to use a PHP-enforced name, such as a class constant: $_SESSION[Stuff::TO_KEEP] = 42; if($_SESSION

Get object keys with the highest value in Javascript

阅读更多关于 Get object keys with the highest value in Javascript

Imagine an object like this: var values = { "2": 1, "53": 2, "56": 4, "57": 9, "61": 2, "62": 16, "63": 2, "398": 24, ... } My goal is, to find the 10 object keys, which have the highest value. In this case: 398, then 62 and so on (= [398, 62, ...] ). I know how I can put this into an array, don't know how to receive the property key though. Important: I can't change the format because it's a server response. I tried with a for (key in values) {} loop but have no idea how to move on. This similar question and it's answer couldn't really help me either. As commented before: Create an array of
