• PHP - Accessing And Replacing Array Contents

  Posted on April 10th, 2009 admin 2 comments

  To access the contents of an array, you use it’s variable name along with its key (index) such as:

  $celebrity_array[0]

  so you can use it’s contents.

  You can use array variables as you would with normal variables and you could easily change it’s contents by using the ‘=’ operator like the following example:

  $celebrity_array[0] = ‘Daniel Craig’ ;

  This line will change the contents of [0] to Daniel Craig. It was Bruce Willis by the way but now he’s gone…

• PHP - Using Arrays (Numerically Indexed)

  Posted on April 9th, 2009 admin 2 comments

  An array is a variable that can store a set of values.

  Numerically Indexed Arrays

  If you wanted to store a set of values in one variable we could do that as follows:

  $celebrity_array[0] = “Bruce Willis”;

  $celebrity_array[1] = “Arnold Swarzennegar”;

  $celebrity_array[2] = “Matt Damon”;

  $celebrity_array[3] = “Liam Neeson”;

  If we then wanted to reference to this we could use these lines:

  echo “A well known action hero is ” . $celebrity_array[0] . ” and ” . $celebrity_array[3] . ” is pretty good as well! “;

  You will also notice that the counter starts at ‘[0]‘ and it’s something you would have to get used to if you haven’t seen an array before.

  Arrays obviously save time and it will make your code look a little tidier. I will go more into arrays in the next blog post as I’m still learning
