How to find first/second element of associative array when keys are unknown?

问题 In PHP when you have an associative array, e.g.: $groups['paragraph'] = 3 $groups['line'] = 3 what is the syntax to access the first or second element of the array when you don't know the value of the keys ? Is there something like in a C# LINQ statement where you can say: $mostFrequentGroup = $groups->first()? or $mostFrequentGroup = $groups->getElementWithIndex(0)? Or do I have to use a foreach statement and pick them out as I do at the bottom of this code example: //should return

Bash “declare -A” does not work on macOS

问题 My guess is that Bash is not updated on macOS. When googling update Bash macOS, I keep getting the bug fix patch.

The OS X bash is likely 3.X. I don't know that OS X has an official update for bash 4+. brew/etc. might

array_splice() - Numerical Offsets of Associative Arrays

由 僤鯓⒐⒋嵵緔 提交于 2019-12-06 21:48:34
I'm trying to do something but I can't find any solution, I'm also having some trouble putting it into works so here is a sample code, maybe it'll be enough to demonstrate what I'm aiming for: $input = array ( 'who' => 'me', 'what' => 'car', 'more' => 'car', 'when' => 'today', ); Now, I want to use array_splice() to remove (and return) one element from the array: $spliced = key(array_splice($input, 2, 1)); // I'm only interested in the key... The above will remove and return 1 element (third argument) from $input (first argument), at offset 2 (second argument), so $spliced will hold the value

Validate dicts in Python

由 痞子三分冷 提交于 2019-12-06 17:06:08
问题 i looking for tool, or examples to/how to validate dictionaries in python. For example, i have dict: test = {'foo' : 'bar', 'nested' : {'foo1' : 'bar1', 'foo2' : 'bar2'} } And now i must validate it. Lets say, value for key foo must be boolean False or non-empty string. Next, if key foo1 have value bar1 , that key foo2 must be int in range 1..10 . I wrote simple function to do this, but this is not what i exactly want. Yea, sure, i can test every single item in dict with if..else , but if

ECMAScript5 deep copy of object and arrays

由 可紊 提交于 2019-12-06 07:52:47
问题 I'd hope to find an example code to do a deep copying of objects in ECMAScript5. The copying should be able to clone Nested objects Nested arrays Nested objects in arrays (clone each array item individually) Note: jQuery.extend() does not seem to handle case 3). Also, I'd hope to do this in clean ECMAScript. Quick googling did not bring up any worthy implementations. 回答1: I finally settled to jQuery.extend() as I couldn't find other good implementations http://api.jquery.com/jQuery.extend/
