[SOLVED] Arrays

[Yesideez]

If I have an array looking like this:

<?php
  $long=array("len" => 0,"word" => "");
?>

How can I add a word onto the end of that list? I need to add the word itself and its length.

[ted_chou12]

you mean:

<?php
$long["add"] = "3";
?>

If you want to add the word and its length then you do this:

$long['len'] = 5;
$long['word'] = 'myword';

<?php 
include 'db2.php';

$words = array ('apple', 'banjo', 'ceiling', 'duck', 'electric');

$long = array();

// add words and lengths to long array

foreach ($words as $w) {
    $long[] = array(
                    'len' => strlen($w),
                    'word' => $w
                );
}

// view the array

echo '<pre>', print_r($long, true), '</pre>';
?>

This is a small sample of the output I received, how can I sort this list by the length of the word?

Array
(
    [0] => Array
        (
            [len] => 1
            [word] => A
        )

    [1] => Array
        (
            [len] => 3
            [word] => DAM
        )

    [2] => Array
        (
            [len] => 3
            [word] => ARK
        )

    [3] => Array
        (
            [len] => 4
            [word] => ZERO
        )

    [4] => Array
        (
            [len] => 3
            [word] => NOR
        )

    [5] => Array
        (
            [len] => 3
            [word] => OR
        )

Fixed by adding this:

<?php
  asort($long);
?>

Thanks to all those who have helped - gratefully apprecated

Word = "OR"

Length = 3

 

???

OK I'm really confused here now. Just reverse sorted the list using this:

<?php
  arsort($long);
?>
This is what I'm using to get the top 10 words in the list:
[code]<?php
  $topten="";
  for ($i=0;$i<10;$i++) {
    $topten.=$long[$i]['word'].'<br />';
  }
?>

This is what I'm getting returned:

A
DAM
ARK
ZERO
NOR
OR 
RE
ORZO 
ERR
ON

I'm confused that although the list shown using print_r has been sorted by the length of the word I can't figure out how to access the sorted data [/code]

[Barand]

Just use rsort().

 

arsort() retains the original array indexes.

Many thanks

Word = "OR"

Length = 3

 

???

Just added my output to show an asterisx either side of the word and found some had a trailing space so I'm going to add trim() so finish it off
