Say this is my string $string = 'product[0][1][0]'; How could I use that string alone to actually get the value from an array as if I had used this: echo $array['product'][0][1][0] I've messed around with preg_match_all with this regex (/\[([0-9]+)\]/), but I am unable to come up with something satisfactory. Any ideas? Thanks in a...

Given that EVAL is Evil how do I create an Array name dynamically: I have a bunch of Arrays and I need to reference different ones depending on what the user clicks. This bit of code gives me the array object: (eval(calendarObject.id + '7')) But eval is bad, so how to do I construct an Array name and then reference it? Here's a bi...
Noobie muddling his way through an Ajax autosuggest form: I've got most of it working, but need to break things down a bit, so I can understand how jQuery refers to things. EDIT: This is my working code, thanks guys. Some problems with delay on the ajaxdiv, not hanging around, but I am working on that ;) function jQajax(ipfield,ajd,dbt...

I came across something very basic but extremely bewildering today. I needed to convert a list to an array. The list contained String instances. Perfect example of using List.toArray(T[]), since I wanted a String[] instance. It would not work, however, without explicitly casting the result to String[]. As a test scenario, I used the fo...
Hi all, I want to recursively search and replace elements in an array. The array is tree based so looks like Object Children Object type A Object type B Object Children Object type A Object etc. I want to be able to replace certain items with other items, so for example, I want to replace all entries in the ...
$var = pack "C2", 0x20, 0x30; seems to work well enough, but now how do I address the elements of the array? Make changes to elements? In-place if possible. The pack/unpack semantics are not very friendly. Currently I'm using substr($var, $index, 1, substr($var, $index, 1) + 10) to add 10 to elements in-place. And for intializers, i...

I have a multi-dimensional array, no problem. How do I interrogator one of the arrays in order to ascertain if it actually holds any data?

However, if I try and use x.length i get the message 'undefined' - so how do I ascertain if the ...
Ok, I have this code: var room = [ { time: 0, people: 0 } ]; and then: time = 5; for( var i in room ) { if( room[i].time < time ){ spliceIndex = i + 1; } } console.log(spliceIndex); And the console reads: 01 - Which means the 1 is concatenated which further means that i is a string, and not an integer as expected. Casting t...
How can I check whether a particular element is inside an array? I don't want to manually write a loop for this; instead I want to use a JavaScript built-in function, maybe something equivalent to new Array(0,1,2,3,6,9,12,15,18).Contains(5) //return false new Array(0,1,2,3,6,9,12,15,18).Contains(1) //return true Edit the question t...
I have a query to get all the compatible phones in a specific country, and in my controller I'm using Set::extract to reduce the untidy result array to just an array of product names. $results = $this->Country->compatiblePhones($country); $compatiblePhones = Set::extract('/p/product_name',$results); $this->set('compatiblePho...
I'm working in a LAMP environment, so PHP is the language; at least i can use python. As the title said i have two unordered integer arrays. $array_A = array(13, 4, 59, 38, 9, 69, 72, 93, 1, 3, 5) $array_B = array(29, 72, 21, 3, 6) I want to know how many integers these array have in common; in the example as you see the result is 2...

I have made a game which is nearly identical to Popcap's Atomica. (http://www.popcap.com/gamepopup.php?theGame=atomica) It's almost finished, except for one important function; blocking the user from moving spheres anywhere. Like, if there is a wall of other spheres in between the sphere the user is trying to move, and the field it is t...
