Handling Multidimensional Arrays

[djdevil89]

Hi :-D

After my daughter was born last year i didnt Really have time for coding anymore.

Lately i started again and now i want to show you how to handle Multidimensional Arrays , the approach i am using here is called Nested Foreach .

It is not always required to use a Nested foreach as you will see later on.

Ok lets assume we have this Array:

Array
(
Array (
 [fruit] => apple
[plant] => tree
[healthy] => yes
)
Array (
[fruit] => orange
[plant] => tree
[healthy] => yes
)
) 

Now usually we can just echo it out using foreach like this

foreach($array as $key => $value)
{
echo "$key \n $value \n";
} 

now for a multidimensional array it will be even easier.

Look at the example below

foreach($value as $fruit)
{
printf("Fruit: %s Plant: %s Healthy: %s,
$fruit['fruit'],$fruit['plant'],$fruit['healthy']);
} 

As you can see we only used the "as" we got rid of the "=>" .
Why?
Well i cant really tell you, as in my expierience it returns a empty string.
Anyways, back on Topic.

Now Sometimes it might become even more confusing when we have a array like this:

Array
(
  Array
(
Array (
[fruit] => apple
[plant] => tree
[healthy] => yes
)
Array (
[fruit] => orange
[plant] => tree
[healthy] => yes
)
)
) 

Here we will use what is called Nested Foreach .

What is a Nested Foreach?

To make it Simple:
A nested foreach is a foreach inside a foreach.



Little Joke on the Side ;-)

Anyways lets build a nested foreach.

foreach($value as $fruit)
{
foreach($fruit as $fruits)
{
///now i use printf you can also use echo to echo it out as mentioned upstairs
echo "$fruits[plant]"; //Example
}
} 

Now this we can repeat as many times as needed depending on how nested the Array is.

Thats all i wanted to show for the moment.

I am sure there are better ways on to do this. But this is my personal Experience :-) hope it helped someone.
