In PHP I could echo data to the web browser to debug.
eg. echo print_r($array)
How do I do that in RoR? I tried with puts with no luck.
Is there a way?

Hello all,
I am trying to raise a click event on a submit button in a html form.
I use the .click() jquery to catch the click event and return true at the end of the function.
When I click on the submit button, the jquery functions are raised and a callback is executed, but the $_POST array is empty.
How can I fix this?

Hi
i need a function that should give me a 10th or 100th array, for example
if i pass 5, it should return 1 to 10
if i pass 67, it should return 1 to 100
if i pass 126, it should return 101 to 200
if i pass 2524, it should return 2001 to 3000
Any guidance?
Hey,
many builtin classes in Java implement Iterable, however String does not. It makes sense to iterate over chars in the String, just as one can iterate over items in regular array. Is there a reason behind it?
I'd like to overload operator[][] to give internal access to a 2D array of char in C++.
Right now I'm only overloading operator[], which goes something like
class Object
{
char ** charMap ;
char* operator[]( int row )
{
return charMap[row] ;
}
} ;
It works ok.. Is it possible to override operator[][] though?
input
23 3 4 4 42 n 23 0 9 9 n n n 3 9 9 x
//according to input,i should create int pointer arrays. pointer arrays starting from 1 (that is initial arrays is arrays[1].when program sees n ,it must be jumb to arrays 2
expected output
arrays[1] 3 4 5 42
arrays[2] 23 0 9 9
arrays[5] 3 9 9
x is stopper
n is comman to create new pointer array

anyone help me how can i write
I have rather long entries being submitted to a database.
How can I create a function to see if this entry has a link within it? Can someone get me started?
Pretty much, I want the function to find any
I'd prefer not to throw the entry into an array. Are there any other ways to accomplish this?
Many Java framework classes implement Iterable, however String does not. It makes sense to iterate over characters in a String, just as one can iterate over items in a regular array.
Is there a reason why String does not implement Iterable?
What are some alternative methods to generate 1000 distinct random integers in the range [0,8000] as opposed to the following:
naive method: generating a number and checking if it's already in the array. O(n^2)
linear shuffle: generate sequence 0 to 8000, shuffle, take the first 1000. O(n)
Hello everyone

I have a class where I'm using __set. Because I don't want it to set just anything, I have an array of approved variables that it checks before it will actually set a class property.
However, on construct, I want the __construct method to set several class properties, some of which are not in the approved list. So when construct happens, and I do $this->var = $value, I of course get my exception that I'm not allowed to set that variable.
Can I get around this somehow?
is it possible to return findOne result as object ..or it always return an array?
i found something about mongo.objects = 1 adding to php.ini ..but did not work for me.

Hi,
Using CodeIgniter, how do I access and display text entered into an input field on a view file (see code below) from my controller file?
// input_view.php
$input_data = array('name' => 'search_field', 'size' => '70');
echo form_input($input_data);
I have several C++ strings with some words. I need to get first word from every string. Then I have to put all of them into a char array. How can I do it?
Thanks i advance!
include
void main()
{ int p[]={0,1,2,3,4};
int *a[]={p,p+1,p+2,p+3,p+4};
printf("%u %u %u %u",a,a,(*a));
}
What should be the output of the above code?
And if we make array p as static(static int p[]), output gets changed .Why?
All the elements should have fixed position in the array after insertion until I explicitly delete them from there. Is there something like this in boost or wherever? Thanks
$post_keys = array_keys($_POST);
$special_keys = array();
for($i=0;$i<count($post_keys);$i++){
if(strpos($post_keys[$i], "special") !== false){
$special_keys[] = $post_keys[$i];
}
}
I have numerous post vars with naming conventions such as special0, special0_time, special0_duration, special1, special1_time etc.... What I want to do is to find out how many main groups there are, so special0, special1 etc... The code I currently have searches all key names that have "special" in it, thus retrieving more than I want.
