Possible Duplicate: Loop an array of array So I know how to traverse an array of even key => value (associative), but I have a weird array where I need to walk through it and print out values: $object_array = array( 'type' => 'I am type', array( 'property' => 'value', 'property_2' => 'value_2' ) ); What I thought I could do is: foreach($object as $key=>$vlaue){ //what now? } So as you can see I am lost, how do I walk through the next array? foreach($object as $key=>$value){ if( is_array($value) ) { foreach($value as $key2=>$value2) { //stuff happens } } else { //other stuff ] } You can try:

I have two associative array having one value in common, like ARRAY 1( [0]=> array(2) { ["ID"]=> "AAAA" ["Name"]=> "Apple" } [1]=> array(2) { ["ID"]=> "BBBB" ["Name"]=> "Avocado" } [3]=> array(2) { ["ID"]=> "CCCC" ["Name"]=> "Banana" } ) Array2 ( [0]=> array(4) { ["ID"]=> "AAAA" ["Taste"]=> "Yumi" ["Location"]=> "France" ["Price"]=> "Cheap" } [1]=> array(4) { ["ID"]=> "CCCC" ["Taste"]=> "Yumi" ["Location"]=> "Africa" ["Price"]=> "Cheap" } [3]=> array(4) { ["ID"]=> "BBBB" ["Taste"]=> "Yumi" ["Location"]=> "America" ["Price"]=> "Expansive" } [3]=> array(4) { ["ID"]=> "HZGA" ["Taste"]=> "Berk" [

Is there a way of making an associative array where each key is a hash of several objects? I'm not interested in inspecting each object's state, but rather the object's identity. var myarray = {}; var a = new A(); var b = new B(); var c = new C(); // + is not right, but illustrates the hashing I'm after. myarray[a + b + c] = 42; The + operator is not right. In java I would arithmetically combine the System.identityHashCode() for each of these three instances and use the result to make my new hash key. Is there some similar mechanic in javascript? Overriding the .toString() method in A, B and C

I need to merge associative arrays and group by the name. Say I have such 3 arrays: ARRAY1 "/path/file.jpg" => 2, "/path/file2.bmp" => 1, "/file3.gif" => 5, ARRAY2 "/path/file.jpg" => 1, "/path/file2.bmp" => 1, "/file3.gif" => 0, ARRAY3 "/path/file.jpg" => 1, "/path/file2.bmp" => 1, I need to merge these arrays to one and group them by filepath and have result of sum of their values. Something like: SELECT filename, SUM(val) FROM files GROUP BY filename But with multiple input arrays. Arrays are short (around 20 elements max). Each array might have different size. one possible way $rtn = array

I am trying to set up PHP queries for MySQL in a way to prevent SQL injection (standard website). I had a couple of INSERT queries where changing this worked well but on the following SELECT I keep getting an error since the update and it looks like the while loop doesn't work with the changes I made (it works well without using the statement as in the old code). Can someone tell me what I am doing wrong here ? New PHP: $stmt = $conn->prepare("SELECT ? FROM TranslationsMain WHERE location LIKE '%calendar weekday%' ORDER BY sortOrder, ?"); $stmt->bind_param('s', $selectedLang); $stmt->execute()

How can I achieve the third array, merging Array1 and Array2? What's the best way to do that in PHP? Many thanks. Array2 has like index (key), the associative value of id in Array1. Array1 Array ( [0] => Array ( [id] => 56 [grade] => 6.7 ) [1] => Array ( [id] => 214 [grade] => 3.2 ) ) Array2 Array ( [56] => 2.4 [214] => 5.8 ) Result wanted Array ( [0] => Array ( [id] => 56 [grade] => 2.4 ) [1] => Array ( [id] => 214 [grade] => 5.8 ) ) foreach($array1 as &$arrayItem) { $arrayItem['grade'] = $array2[$arrayItem['id']] } Here you will have array 1 merged as you wished 来源： https://stackoverflow.com

I'm having trouble wrapping my head around this, any help would be GREAT ... I have an array $stores that is structured like so: Array ( [0] => Array ( [id] => 123 [name] => 'Store A' ) [1] => Array ( [id] => 345 [name] => 'Store B' ) [2] => Array ( [id] => 567 [name] => 'Store C' ) [3] => Array ( [id] => 789 [name] => 'Store D' ) ) I want to extract the 'id' values from this array into a simple array that looks this: $simple = array(123,345,567,789); If you use php 5.5+, array_column() is quite useful : $simple = array_column($yourarray,'id'); http://php.net/array_column Calimero definitely
