问题 Is it possible to pass BASH associative arrays as argv to PHP scripts? I have a bash script, that collects some variables to a bash associative array like this. After that, I need to send it to PHP script: typeset -A DATA DATA[foo]=$(some_bash_function "param1" "param2") DATA[bar]=$(some_other_bash_function) php script.php --data ${DATA[@]} From PHP script, i need to access the array in following manner: <?php $vars = getopt("",array( "data:" )); $data = $vars['data']; foreach ($data as $k=>

问题 I am in the process of getting to grips with the Golang way of doing things. I'd be much obliged to anyone who might be able to help with the following. First some sample code package main import ( "log" "os" ) func logIt(s string) { f, _ := os.OpenFile("errors.log", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666) defer f.Close() log.SetOutput(f) log.Println(s) } type iAm func(string) func a(iam string) { logIt(iam + " A") } func b(iam string) { logIt(iam + " B") } func c(iam string) { logIt(iam + "

问题 Using PHP I need to merge 2 arrays (of equal length into one associative array) here is an excerpt from my current data set: [1] => Array ( [0] => C28 [1] => C29 ) [2] => Array ( [0] => 1AB010050093 [1] => 1AB008140029 ) both elements [1] and [2] are actually a lot longer than just 2 sub-elements (like I said, this is an excerpt). The deal is that "C28" in the first array corresponds to "1AB010050093" in the second array, and so on... The result I need is to create a new associative array

问题 Is it possible to create a multidimensional, associative array in VBScript? I'm trying to recreate the following JScript code in VBScript: names["teachers"] = ["Helen","Judy","Carol"]; names["students"] = ["George","John","Katie"]; For (var i=0; i<names["teachers"].length; i++) { Response.Write(names["teachers"][i]); } My attempted VBScript: dim names SET names = CreateObject("Scripting.Dictionary") names.Add "teachers", Array("Helen","Judy","Carol") names.Add "students", Array("George","John

问题 I want to dissect an array like this: [ "ID", "UUID", "pushNotifications.sent", "campaigns.boundDate", "campaigns.endDate", "campaigns.pushMessages.sentDate", "pushNotifications.tapped" ] To a format like this: { "ID" : 1, "UUID" : 1, "pushNotifications" : { "sent" : 1, "tapped" : 1 }, "campaigns" : { "boundDate" : 1, "endDate" : 1, "pushMessages" : { "endDate" : 1 } } } It would be great if I could just set a value on an associative array in a keypath-like manner: //To achieve this:

问题 I've a dynamically generated very huge array called $test_package_data . For your understanding I'm giving below the contents of array $test_package_data . Now what I want to achieve is convert the value of an array key $test_duration = ConvertTimeStampToTimeFormate($some_key['test_duration']); In short I want to update the value of a key ['test_duration'] eveywhere in the array. But not understanding how should I loop over the array and achieve the desired result. 回答1: You can use array_walk

问题 I have an associate array that looks something like this: array ( 'device_1' => array('a','b','c','d'), 'device_2' => array('x','y','z') ) How can I implode the array into a standard array like this: array(0 => 'a', 1 => 'b', 2 => 'c', 3 => 'd', 4 => 'x', 5 => 'y', 6 => 'z') Or more simply: array('a','b','c','d','e','x','y','z') Does anybody know what I should do? 回答1: You can do this: $result = call_user_func_array('array_merge', $array); which will give you: Array ( [0] => a [1] => b [2] =>

问题 For example, I have an array of: array( array( ['make']=>ford ['color']=>blue ['type']=>automatic ), array( ['make']=>chevrolet ['color']=>red ['type']=>manual ) Is is possible to find in PHP the value of a known key when all I have to go on is the value of another key? Say for example, I have the value "blue" and I know that it's in the "color" key, can I now find what the value of "car" is from this information? The known value of the known key is unique. (in this example, there couldn't be

问题 As a follow-up to Flatten Arbitrary JSON, I'm looking to take the flattened results and make them suitable for doing queries and updates back to the original JSON file. Motivation : I'm writing Bash (4.2+) scripts (on CentOS 7) that read JSON into a Bash associative array using the JSON selector/filter as the key. I do processing on the associative arrays, and in the end I want to update the JSON with those changes. The preceding solution gets me close to this goal. I think there are two

问题 i m doing associative list in prolog i seen this topic but i dont understand the code. Associative Lists in Prolog For checking list is associative isn't enough do this: lists([_X, _Y]). lists([[H|_T]|L],[H|T]):- lists(L,T). Because for first /1 i check if have element in this way [a,3] and /2 take list of list [[a,4],[a,3]] in this way. so first pass call list/2 on [a,3], and check true for base case, and after call [a,4] and call true for base case too. I wrong something, but i don't see,
