Instead of asort, use asorti(source, destination) which sorts the indices into a new array and you won’t have to copy the array. Then you can use the destination array as pointers into the source array. For your example, you would use it like this: n=asorti(chr_count, sorted) for (i=1; i<=n; i++) { print sorted[i] ” : … Read more
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
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
If you’re using Bash 4.3 or newer, the cleanest way is to pass the associative array by name reference and then access it inside your function using a name reference with local -n. For example: function foo { local -n data_ref=$1 echo ${data_ref[a]} ${data_ref[b]} } declare -A data data[a]=”Fred Flintstone” data[b]=”Barney Rubble” foo data You … Read more
You can avoid having to create a function by referencing the first entry returned from Object.keys(): var firstKey = Object.keys(data)[0]; For the first entry from a sorted key list, simply add a call to the .sort() method: var firstKey = Object.keys(data).sort()[0];
What you have is the most clear option. But you could shorten it using array_fill_keys, like this: $database = array_fill_keys( array(‘dbdriver’, ‘dbhost’, ‘dbname’, ‘dbuser’, ‘dbpass’), ”); But if the user has to fill the values anyway, you can just leave the array empty, and just provide the example code in index.php. The keys will automatically … 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); } ?>
Is pure php ok? $array = array_values($array); Source
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
