dynamic array

[hassank1]

I want to create a dynamic array ex: words[]

 

and then later.. (when certain event occurs) I want to add elements to it..

 

how can I do that?

[bobbinsbro]

to add an element to on to the end of the array:

$words[] = "new element";

or

array_push($words, "new element 1", "new element 2"....);

 

to add an element to the head of the array:

array_unshift($words, "new element");

 

to add an element in the middle of an array:

array_splice($words, $position, 0, "new element");

where $position is the index at which you want to insert the new element.

$words = array();

// do your stuff...then later

$words[] = "hello";  // $words[0] will be 'hello'
$words[] = "goodbye";  //words[1] will be 'goodbye'

//loop through all of the words and print each one out on a separate line
foreach($words as $word) {
    echo "$word<br />";
}

 

Hope that helps.
