Tutorial - How to use arrays in php
June 26, 2008 – 8:00 pmUsing arrays in PHP can be a very powerful technique of handling data.
If you are not familiar with arrays in PHP then use simple code!
Example of simple code.
$fruit['apples'] = 'I like apples';
$fruit['oranges'] = 'I like oranges';
$fruit['banana'] = 'I like bananas';
Example of advanced code.
$fruit = array("apples" => 'I like apples', "oranges" => 'I like oranges', "banana" => 'I like bananas');
Using advanced code saves lines in the source code but if you are not familiar with arrays it could be harder to troubleshoot if you get parse errors. Once you feel confident with arrays then I would recommend using advanced code.
Reading from arrays.
Arrays are very simple to read from. Using our example code above, to see the value of Apples we would use
echo $fruit['apples'];
this would return: I like apples
Looping through arrays
Looping through arrays is easy too, but this is where people usually get stuck. Just look at it from a logical point of view. We are going to use the foreach function to go through the array.
foreach($fruit as $key => $value) {
echo $key . ' : ' . $value . '<br />';
}
This would return:
apples : I like apples
oranges: I like oranges
banana: I like bananas
Using the foreach function above, think of $key as the name and $value as the information we assigned.
