associative

问题 I cannot find any examples, in books or on the web, describing how one would properly initialize an associative array by name only (with empty values) - unless, of course, this IS the proper way(?) It just feels as though there is another more efficient way to do this: config.php class config { public static $database = array ( 'dbdriver' => '', 'dbhost' => '', 'dbname' => '', 'dbuser' => '', 'dbpass' => '' ); } // Is this the right way to initialize an Associative Array with blank values? //

问题 I would like to print out the content of an associative array. For this I'm using Data::dumper. So, for exemple, if the associative array is called "%w", I write : print OUT Dumper(\%w); Here's the problem: there are some words like "récente" that are printed out as "r\x{e9}cente". If I write just : print OUT %w; I've no problems, so "récente" it will be printed out as "récente". All text files used for the script are in utf8. Moreover I use the module "utf8" and I specify always the

问题 How do I sort an associative array in bash? For example, I have array in bash: [0,0]="Max" [0,1]="25" [1,0]="Vladimir" [1,1]="0" [2,0]="Mayki" [2,1]="50" Output must be: Mayki - 50 Max - 25 Vladimir - 0 I don't know how sort this array. Additional Info: I parse assoc array from text file ("log.txt") #!/bin/bash declare -A b_array # Read the file in parameter and fill the array named "array" getArray() { i=0 w=9 count=10 while read line # Read a line do k=0 #array[i]=$line # Put it into the

问题 I'm writing a Bash script to simplify file copies from our main site to multiple agencies. In this script, I'm trying to use a variable as an associative array name but I optain an error, here is the code : #!/bin/bash declare -A GROUP1 declare -A GROUP2 declare -A GROUP3 declare -A ARRAY GROUP1["SITE1"]="x.x.x.x" GROUP1["SITE2"]="y.y.y.y" GROUP1["SITE3"]="z.z.z.z" GROUP2["SITE1"]="1.1.1.1" GROUP2["SITE2"]="2.2.2.2" GROUP2["SITE3"]="3.3.3.3" GROUP2["SITE1"]="a.a.a.a" GROUP2["SITE2"]="b.b.b.b"

问题 I am trying to create an array in javascript which will allow me to access data like this: var name = infArray[0]['name']; however I cant seem to get anything to work in this way. When i passed out a assoc array from php to javascript using json_encode it structured the data in this way. The reason why i have done this is so i can pass back the data in the same format to php to execute an update sql request. 回答1: JavaScript doesn't have associative arrays. It has (numeric) arrays and objects.

问题 I have this code: $dbInstance = DB_Instance::getDBO(); $statement = $dbInstance->prepare("SELECT id, name FROM language ORDER BY id"); $statement->execute(); $rows = $statement->fetchAll(); //Create associative array wuth id set as an index in array $languages = array(); foreach($rows as $r) { $languages[$r['id']] = $r['name']; } return $languages; I can't figure out how to use PDO-statement to achieve the same result that array $languages produces. I've tried some different fetch_styles. I

问题 I've seen numerous examples on how to take a CSV file and then create an associative array with the headers as the keys. For example: Brand,Model,Part,Test Honda,Civic,123,244 Honda,Civic,135,434 Toyota,Supra,511,664 Where it would create an Array such as Array[$num][$key] where $key would be Brand, Model, Part, Test. So If I wanted to access the test value "434" I would have to loop every index in the array and then ignore any Brands that were not honda, and any models that were not Civic

问题 This should be a simple thing to solve... I have got these estatements when a user logs in: $query = $conn->prepare("SELECT * FROM admins WHERE username = :user AND password = :pass"); $query->bindValue(":user", $user); $query->bindValue(":pass", md5($pass)); $query->execute(); Now if the user exists, I return the user information from the database, but if not, I return false instead... if($query->rowCount() > 0) { $admininfo = $query->fetchAll(PDO::FETCH_ASSOC); } else { return false; } But

问题 I am learning Scala, and playing with right associate unapply object. I know that if the name ends with ':' then it becomes right associative. However, there seems to be some strange restrictions on the naming e.g. These are invalid object cons: { def unapply(value: String): Option[(Char, List[Char])] = ??? } object :_cons_: { def unapply(value: String): Option[(Char, List[Char])] = ??? } These are valid object cons_: { def unapply(value: String): Option[(Char, List[Char])] = ??? } object >>:
