Put Any Php Codes Here If You Wish Thank-you JamieHxD :slight_smile: :wink:

Hi Jamie.

What code are you looking for? I wonder if some links to basic, or getting started, tutorials would be better for you.

Iā€™ll have a look around for some, but maybe other members know of some?

Thereā€™s Michael Morrisā€™ 'PHP Basicsā€™ thread here at SitePoint, you should read that. It points to the [URL=ā€œhttp://www.php.net/manual/en/index.phpā€]PHP Manual a lot too, however the guide at the manual isnā€™t too good IMO.

4

Ok Thank-you Iā€™ve Looked At It And I Donā€™t Get Any Of It :s

5

Is there a part of the language you want to learn first? Strings, Arrays ā€¦

6

arrayā€™s Please. :slight_smile:

7

Sure. :wink:

Make sure you (try to) read the manual section on arrays too, but here you go.


<?php
/*
  Declare an array
*/
$array = array();

/*
  Add some elements
*/
$array[] = 'jamie';
$array[] = 'anthony';
$array[] = 'sitepoint';

/*
  Array indicies start at 0. So,
  jamie is at 0, anthony is at 1
  and sitepoint is at 3.
*/

/*
  display the item at index 1
*/
echo $array[1], PHP_EOL; #anthony

/*
  display the item at index 0
*/
echo $array[0], PHP_EOL; #jamie

/*
  You can also display them all
  using a loop, or 'foreach'.
*/
foreach($array as $name){
  echo $name, PHP_EOL;
}

Hereā€™s another variation.


<?php
/*
  Declare an array
*/
$users = array();

/*
  Add some elements
*/
$users['jamie'] = 13;
$users['anthony'] = 31;

foreach($users as $name => $age){
  echo $name, ' is ', $age, PHP_EOL;
}

/*
  jamie is 13
  anthony is 31
*/

Ahh Ok Thank-You I Think Iā€™ve Got The Jist Now. :slight_smile:

Iā€™ve Eited Youā€™re Code As It Came Up With Anthony Jamie Jamie Anthony Sitepoint so i took out the echo to sort it out. :slight_smile: Here this one.

<?php
$array = array();
$array[] = 'jamie';
$array[] = 'anthony';
$array[] = 'sitepoint';

foreach($array as $name){
  echo $name, PHP_EOL;
}
11

That looks good.

How do you think you can reverse the array so that the output is sitepoint, anthony, jamie without altering $array.

12

like this

<?php
$array = array();
$array[] = 'sitepoint';
$array[] = 'anthony';
$array[] = 'jamie';

foreach($array as $name){
  echo $name, PHP_EOL;
}
13

Nope, youā€™ve altered $array. :wink:



<?php
$array = array();
$array[] = 'jamie';
$array[] = 'anthony';
$array[] = 'sitepoint';

/* you can change anything below here */
14

Take a look at this list of array functions and read the description, are there any there that sound like they maybe useful? :wink:

15

absolutely no idea. :?

16

Try thisā€¦

PHP: array_reverse - Manual

17

I Can Not Do It. :frowning:

18

Ahhh Ha Iā€™ve Found It. Here

 <?php

$array = array();
$array[] = 'jamie';
$array[] = 'anthony';
$array[] = 'sitepoint';

$trans = array("jamie" => 3, "anthony" => 2, "sitepoint" => 1);
$trans = array_flip($trans);
print_r($trans);
19

Not quite. :stuck_out_tongue:

You were on the right track though!

<?php
$array = array();
$array[] = 'jamie';
$array[] = 'anthony';
$array[] = 'sitepoint';

/* you can change anything below here */

foreach(array_reverse($array) as $name){
  echo $name, PHP_EOL;
}

oh ok thank-you. :slight_smile:
