I found a solution. Scala reference says in section 6.12.3 Infix Operations: The associativity of an operator is determined by the operator’s last character. Operators ending in a colon ‘:’ are right-associative. All other operators are left-associative. Therefore it was enough to rename >> to >>:. It took me some time to realize that while … Read more
They both do the same, but udiff-assoc compares the DATA with the user supplied function, while diff-uassoc compares the INDEX with the user supplied function. As an answer to @lonsesomeday : as indicated by the ‘u’, diff_assoc will use internal functions for all comparisons, and udiff_uassoc uses provided callbacks for index and data comparison. http://www.php.net/manual/en/function.array-diff-uassoc.php … Read more
There are no such things as associative arrays in Javascript. You can use object literals, which look like associative arrays, but they have unordered properties. Regular Javascript arrays are based on integer indexes, and can’t be associative. For example, with this object: var params = { foo: 1, bar: 0, other: 2 }; You can … Read more
Too many long solutions. I’ve always found this to be the simplest: <?php /* Map Rows and Loop Through Them */ $rows = array_map(‘str_getcsv’, file(‘file.csv’)); $header = array_shift($rows); $csv = array(); foreach($rows as $row) { $csv[] = array_combine($header, $row); } ?>
Objects in JavaScript can be thought of as associative arrays, mapping keys (properties) to values. To remove a property from an object in JavaScript you use the delete operator: const o = { lastName: ‘foo’ } o.hasOwnProperty(‘lastName’) // true delete o[‘lastName’] o.hasOwnProperty(‘lastName’) // false Note that when delete is applied to an index property of … Read more
Javascript doesn’t have “associative arrays” the way you’re thinking of them. Instead, you simply have the ability to set object properties using array-like syntax (as in your example), plus the ability to iterate over an object’s properties. The upshot of this is that there is no guarantee as to the order in which you iterate … Read more
I had exactly the same problem last week and thought about it for quite a while. It seems, that associative arrays can’t be serialized or copied. There’s a good Bash FAQ entry to associative arrays which explains them in detail. The last section gave me the following idea which works for me: function print_array { … Read more
