When you attempt to install the Spreadsheet_Excel_Writer and get this error:

Failed to download pear/Spreadsheet_Excel_Writer within preferred state “stable”, latest release is version 0.9.1, stability “beta”, use “channel://pear.php.net/Spreadsheet_Excel_Writer-0.9.1? to install
Cannot initialize ‘channel://pear.php.net/Spreadsheet_Excel_Writer’, invalid or missing package file
Package “channel://pear.php.net/Spreadsheet_Excel_Writer” is not valid

do the following commands:

pear config-set preferred_state beta
pear install —onlyreqdeps Spreadsheet_Excel_Writer

Include the onlyreqdeps switch so that the dependency package PEAR OLE is installed

Hope that will help!

Alexa is a company owned by Amazon.com that measures web traffic on almost every website on the internet through their toolbar plugin. The Alexa Ranking is a ranking that is based on the traffic to a website. This ranking becomes an important thing in leveraging your website as a sell point to advertisers, sponsors, buyers, readers and whoever else wants a piece of your material. Therefore for some website owners it’s important to put alexa rank in their page.

If you want to put alexa rank in your page, here is the code:

<?php

Class Alexa {

function getAlexaRank($domain)
{
$remote_url = ‘http://data.alexa.com/data?cli=10&dat=snbamz&url=’ . trim($domain);
$xml = simplexml_load_file($remote_url);
if(isset($xml->SD[1]->POPULARITY['TEXT'])){
return number_format($xml->SD[1]->POPULARITY['TEXT']);
} else {
return 0;
}
}
}
?>

and

$alexa = new Alexa;
$alexarank = $alexa->getAlexaRank($domain);
echo “Alexa Rank: ” . $alexarank;

where $domain is your domain name.

ps: I got this script while googling, unfortunately I forgot the source.

The following are php configurations that must be considered when writing php program for uploading file to server:

• allow_url_fopen – should be on
• file_uploads – should be on
• upload_max_file_size – is the sum of the sizes of all the files that you are uploading. This should be larger than the files you are trying to upload.
• post_max_size – should be larger than the value that you set for upload_max_file_size.
• memory_limit – this directive has any effect only if you have used the –enable-memory-limit option at configuration time.
• upload_tmp_dir – should be a valid directory and have correct permissions for the server to write to.
• max_execution_time – should provide sufficient time.

Files are usually posted to the server in a format known as ‘multipart/form-data’.

<form method=”post” enctype=”multipart/form-data”>

Tips: if you are encountering file uploading trouble, first try uploading a small text file.
