Step 2 - Print complete php arrays


PHP print array


The other most frequently used php print array method is when you want to display all values from an array. Using our colorList example array you can create a loop to display all values. Here you have more possibilities but PHP has a special loop for this purpose. It is called foreach. With foreach you can visit all elements in a loop and display its value, key or both if you want. The most simplest code example looks like this:

Code:
  1. foreach ($colorList2 as $value) {
  2. echo $value."";
  3. }
However if you want to display the keys as well you can write your code in the following format:
Code:
  1. foreach ($colorList2 as $key => $value) {
  2. echo $key." - ".$value."";
  3. }

Print array for debugging purpose

Finally I will show you how to print the complete array content with a single function call. PHP has 2 built in functions to display a complete array. They are the print_r and the var_dump. Both are doing the same but var_dump gives you a little bit more information. It displays not only key and values but variable types as well.
However the usage are similar:
Code:
  1. echo "Dump colorList2 with print_r";
  2. print_r($colorList2);
  3. echo "Dump colorList2 with var_dump";
  4. var_dump($colorList2);
