Verifying array element contains text

[unkwntech]

I have the following code:

<?php
require 'lib.xml.php';  //XML parser to array parser from http://www.phpclasses.org/browse/package/3598.html
$xml = new Xml();
$xml->parse('http://weather.yahooapis.com/forecastrss?p=92115');
$temp = $xml->pOut[0]['rss'][2]['channel'];
for($i=0;$i<count($temp);$i++)
{
if(!is_array($temp[$i]) || !is_string($temp[$i]) || is_null($temp[$i]))
 {
	unset($temp[$i]);
 }
}
print_r($temp);
?> 

 

when $temp = $xml->pOut[0]['rss'][2]['channel']; it contains a LARGE array with several empty elements:

 

Array

(

    [0] =>

 

 

    [1] =>

 

    [2] =>

 

    [3] =>

 

    [4] =>

 

    [5] =>

 

    [6] =>

 

    [7] =>

 

    [8] =>

 

    [9] =>

 

    [10] =>

 

    [11] =>

 

    [12] =>

 

    [13] =>

 

    [14] => Array

        (

              //Data

        )

 

after the loop all that has been removed are elements 1-7 leaving 8-13 which seem to also be empty, how can I get rid of these also?

Use simplexml (if you have it available of course). It's really easy.

This may be a solution but for the time being I still need to answer the question, as this is not the first time, I've had the problem.

 

Also I did not see what version, that was included in do you know?

condition !is_array($temp[$i]) || !is_string($temp[$i]) || is_null($temp[$i]) is allways true

if $temp[$i] is array 2nd part is true, if not true is 1st part
