问题 I have an array like this (it's just a little overview but it has 2000 and more lines like this): @list = ( "affaire,chose,question", "cause,chose,matière", ); I'd like to have this output: %te = ( affaire => "chose", "question", chose => "affaire", "question", "cause", "matière", question => "affaire", "chose", cause => "chose", "matière", matière => "cause", "chose" ); I've created this script but it doesn't work very well and I think is too much complicated.. use Data::Dumper; @list = (

问题 In a past paper for an exam I have the question: Months can be represented in different ways, for example as numbers (1, 2, …, 12), or as three- letter month names (Jan, Feb, …, Dec). Suggest how associative arrays in awk can be used to translate from three-letter month names to month numbers, and vice versa, to translate month numbers to three-letter month names. So I thought I would use associative arrays in the format say the input of the month is in $1: number_to_month["Jan"] = 1; print

问题 There is an associative array with only one pair key=>value . I don't know it's key, but I need to get it's value: $array = array('???' => 'value'); $value = // ?? $array[0] doesn't work. How can I get it's value? 回答1: You can also do either of the following functions to get the value since there's only one element in the array. $value = reset( $array); $value = current( $array); $value = end( $array); Also, if you want to use array_keys() , you'd need to do: $keys = array_keys( $array); echo

问题 I want to execute a SQL query inside PL/SQL and populate the results into an associative array, where one of the columns in the SQL becomes the key in the associative array.

问题 I use several associative arrays in my PHP application and I'm using PHP documentor to comment my sources. I never really did specify comments for the arrays in an array, but now I need to do that and don't know how. $array = array('id' => 'test', 'class' => 'tester', 'options' => array('option1' => 1, 'option2' => 2)) How do I comment this array in the correct way for @var and @param comments? I could do this like this, but I don't know if this is correct: @param string $array['id'] @param

问题 Let's say I've got an Article s collection, and I want to fetch the popular articles. So first, I make a scopePopular() method in the Article method. Very simple. Now I want to fetch their id s, so I'll do this: Article::popular->pluck('id'); The result will be an associative array: [ 0 => 1, 1 => 34, 2 => 17 ... ]; I want to get a normal array, without the keys, Like: [1, 34, 17] I know I can just do something like this: array_values(Article::popular->pluck('id')); But I believe Laravel has
