Arrays should only have entries with numerical keys (arrays are also objects but you really should not mix these). If you convert an array to JSON, the process will only take numerical properties into account. Other properties are simply ignored and that’s why you get an empty array as result. Maybe this more obvious if … Read more
You don’t. Your array doesn’t have a key [1]. You could: Make a new array, which contains the keys: $newArray = array_keys($array); echo $newArray[0]; But the value “one” is at $newArray[0], not [1]. A shortcut would be: echo current(array_keys($array)); Get the first key of the array: reset($array); echo key($array); Get the key corresponding to the … Read more
In PHP, associative arrays are implemented as hashtables, with a bit of extra functionality. However technically speaking, an associative array is not identical to a hashtable – it’s simply implemented in part with a hashtable behind the scenes. Because most of its implementation is a hashtable, it can do everything a hashtable can – but … Read more
Just use a regular JavaScript object, which would ‘read’ the same way as your associative arrays. You have to remember to initialize them first as well. var obj = {}; obj[‘fred’] = {}; if(‘fred’ in obj ){ } // can check for the presence of ‘fred’ if(obj.fred) { } // also checks for presence of … Read more
array_merge() is more efficient but there are a couple of options: $array1 = array(“id1” => “value1”); $array2 = array(“id2” => “value2”, “id3” => “value3”, “id4” => “value4”); $array3 = array_merge($array1, $array2/*, $arrayN, $arrayN*/); $array4 = $array1 + $array2; echo ‘<pre>’; var_dump($array3); var_dump($array4); echo ‘</pre>’; // Results: array(4) { [“id1”]=> string(6) “value1” [“id2”]=> string(6) “value2” [“id3”]=> … Read more
Your YAML looks okay, or you can configure an array of hashes like this : content_prices: – country: AU price: 6990000 – country: AT price: 4990000 – country: BE price: 4990000 Which will load as the following hash: {“content_prices”=>[ {“country”=>”AU”, “price”=>6990000}, {“country”=>”AT”, “price”=>4990000}, {“country”=>”BE”, “price”=>4990000}]} But that still doesn’t give you any reference to the … Read more
I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools…References menu in the VBE.) It pretty much works with any simple value that can fit in a variant (Keys can’t be arrays, and trying to make them objects doesn’t make … Read more
Make sure the version of bash being invoked as interpreter at the top of your shell script (#!/bin/bash or whatever) is also version 4. If you’re doing: bash –version and it’s giving you v4, do a which bash to check it’s location.
In bash version 4 associative arrays were introduced. declare -A arr arr[“key1”]=val1 arr+=( [“key2”]=val2 [“key3”]=val3 ) The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc. for key in ${!arr[@]}; do echo ${key} ${arr[${key}]} done Will loop over all … Read more
You can simply do this $data += array($category => $question); If your’re running on php 5.4+ $data += [$category => $question];
