Step 2 - Creating an array


PHP Array tutorial


There are more ways to create an array in PHP. Maybe the most easiest way to create our color list array is the following:

Code:
  1. $colorList = array("red","green","blue","black","white");
n other sollution is to initialise array elements one-by-one as follows:
Code:
  1. $colorList[0] = "red";
  2. $colorList[1] = "green";
  3. $colorList[2] = "blue";
  4. $colorList[3] = "black";
  5. $colorList[4] = "white";
If you don't want to bother about numbering - I will explain it later - you can create your array as this:
Code:
  1. $colorList[] = "red";
  2. $colorList[] = "green";
  3. $colorList[] = "blue";
  4. $colorList[] = "black";
  5. $colorList[] = "white";
As you can see this is almost similar to the other but here we didn't write any number between the square brackets. In this case PHP makes the numbering internally from 0 to 4. This function is the so called auto-incremented keys.
