![Tell me more
There are 3 types of arrays in PHP
Indexed: Accessed via a particular Index.
E.g. $x[0];
Associative: Accessed via a particular key.
E.g. $x[‘name’];
Multidimensional: Contain more than one arrays of same or different types.
E.g. $x[0][1];](https://image.slidesharecdn.com/phparrays-151127181029-lva1-app6892/85/Php-arrays-3-320.jpg)
![Indexed arrays
I want some action! Show me how to view contents of the array we just
created.
Okay, here you go – This is how you access the elements.
Echo $country[1]; #Will show you Canada.
Why?
Arrays start with a ‘0’ as primary Index.](https://image.slidesharecdn.com/phparrays-151127181029-lva1-app6892/85/Php-arrays-5-320.jpg)
![Indexed arrays - Show me more!
That was kids stuff. Show me how to print all the elements.
Hmm, you want more action huh?
Here you go –
For($anyvariable=0; $anyvariable<count($country); $anyvariable++){
Echo $country[$anyvariable];
}
Note: count function will contain the length of the array. In this case 3.](https://image.slidesharecdn.com/phparrays-151127181029-lva1-app6892/85/Php-arrays-6-320.jpg)
Php arrays
- 1. PHP Arrays ELEGANT AND EASY WAYS TO WORK WITH THEM. PART1
- 2. I wonder what arrays are all about! Well, to begin with they are used to store data. Just like you store data in variables E.g. $x=5; The major difference between arrays and variables being: Variables aren’t as flexible as arrays. Arrays can be used to store Homogeneous(All Ints or Floats) or Heterogeneous(Int, Float, Char) data.

- 4. Indexed arrays How do I declare and initialize them? $country = array(“India”, “Canada”, “USA”); That’s how you do it. Don’t use the other way. It’s time consuming!

- 7. Indexed arrays - Pay back time! Are you kidding me? “Practice makes a man perfect” You show me more; assignment time! a. Create an array with numbers 1 to 20 inside it. b. Show me how you’d print every odd number between 3 and 20. c. If that was fun, when you arrive at the 17 make it yell out “Seventeen”. Did you make it till here already? Very good. I appreciate your time and efforts.
