Editing Array Elements
1:36Have you ever misspelled a word? Or maybe changed your mind about something? Programming is no different, and sometimes we'll need to edit an array element. In this video we'll see how to modify an element by specifying it's key.
Have you ever misspelled a word or
maybe changed your mind about something?

Programming is no different,
and sometimes,
0:05
we'll need to edit an array element.
0:07
Maybe we misspelled a word, or maybe we
want to specify HTML 5 and not just HTML.
0:09
An array is a type of variable,
so you can update or
0:16
edit your array in much the same
way as you would another variable.
0:19
Each individual element
is also a variable, so
0:23
you can update or
edit individual elements as well.
0:26
Let's remove this unset of the array.
0:31
Then I use the array variable $learn and
set it equal to the string,
0:34
'my learning list'.
0:39
As we demonstrated before
when adding values,
0:43
the learn list no longer
contains an array.
0:46
It's a string with this new value.
0:50
You probably don't wanna change
your array into a string.
0:52
So let's remove that line.
0:56
What you may want to change is one of
the string values within your array.
0:59
To update a certain
element within the array,
1:05
you specify that element using its key.
1:08
$learn[0] = 'Email'.
1:11
My first element is now
replaced with this new value.
1:20
But none of my other
elements have changed.
1:25
There are many more ways to change and
manipulate arrays.
