range

Is it possible to get a range with PHP from A to ZZ*? a b c ... aa ... zx zy zz For me this didn't work: range('A', 'ZZ'); It's for PHPExcel, when it gives BE as highest field i'd run through all colums. In this case i only get A, B: range ('A', 'BE') Just Try this- (tested working fine) function createColumnsArray($end_column, $first_letters = '') { $columns = array(); $length = strlen($end_column); $letters = range('A', 'Z'); // Iterate over 26 letters. foreach ($letters as $letter) { // Paste the $first_letters before the next. $column = $first_letters . $letter; // Add the column to the

Does anyone know of any cross-browser user selection range libraries written in javascript? I found a few jQuery plugins, (which quite frankly are too limiting and very buggy). I would just like to know what you have found out there. Don't send me googling this again, (I've spent days working on all this). Hopefully, this can be where future programmers can find the answer. Tim Down I've developed a cross-browser Range and selection library called Rangy . Its core is not dissimilar in concept to IERange but goes beyond it in terms of implementation of the DOM level 2 Range and HTML5 selection

Both my professor and this guy claim that range creates a list of values. "Note: The range function simply returns a list containing the numbers from x to y-1. For example, range(5, 10) returns the list [5, 6, 7, 8, 9]." I believe this is to be inaccurate because: type(range(5, 10)) <class 'range'> Furthermore, the only apparent way to access the integers created by range is to iterate through them, which leads me to believe that labeling range as a lists is incorrect. In Python 2.x, range returns a list, but in Python 3.x range returns an immutable sequence, of type range . Python 2.x: >>>

I'm parsing some text and calculating the weight based on some rules. All the characters have the same weight. This would make the switch statement really long can I use ranges in the case statement. I saw one of the answers advocating associative arrays. $weights = array( [a-z][A-Z] => 10, [0-9] => 100, ['+','-','/','*'] => 250 ); //there are more rules which have been left out for the sake of clarity and brevity $total_weight = 0; foreach ($text as $character) { $total_weight += $weight[$character]; } echo $weight; What is the best way to achieve something like this? Is there something

Is there an existing way to parse the HTTP_RANGE header correctly in PHP? Thought I'd ask here before re-inventing the wheel. I am currently using preg_match('/bytes=(\d+)-(\d+)/', $_SERVER['HTTP_RANGE'], $matches); to parse the header but that does not cover all possible values of the header so I am wondering if there is a function or library that can do this already? Thanks in advance. BalusC Rather use regex to test it before sending a 416 . Then just parse it by exploding on the comma , and the hyphen - . I also see that you used \d+ in your regex, but those are actually not required. When

I understand how functions like range() and zip() can be used in a for loop. However I expected range() to output a list - much like seq in the unix shell. If I run the following code: a=range(10) print(a) The output is range(10) , suggesting it's not a list but a different type of object. zip() has a similar behaviour when printed, outputting something like <zip object at "hexadecimal number"> So my question is what are they, what advantages are there to making them this, and how can I get their output to lists without looping over them? You must be using Python 3. In Python 2, the objects

Possible Duplicate: Color coding based on number I want for a user to be able to select from a range from 1-100, where as the numbers become less than 50, the color of the area becomes darker green, and as the color becomes closer to 100, the color becomes more red. I am trying to make it so that as the range in more towards the center, the color should be close to white (where 50 = full white). I tried the answer from here: Generate colors between red and green for a power meter? to no avail.... 50 ends up being a muddled green... I have the following html: <span><span class="value">50</span>

I just discovered that at one point, the C++11 draft had std::begin / std::end overloads for std::pair that allowed treating a pair of iterators as a range suitable for use in a range-based for loop (N3126, section 20.3.5.5), but this has since been removed. Does anyone know why it was removed? I find the removal very unfortunate, because it seems there is no other way to treat a pair of iterators as a range. Indeed: The lookup rules for begin/end in a range-based for loop say that begin/end are looked for in 1) as member functions of the range object 2) as free functions in "associated
