It is highly recommended to increase the following limits in /etc/php.ini so that uploads through PHP will work as expected.

# php -r"phpinfo();" | grep upload
file_uploads => On => On
max_file_uploads => 20 => 20
upload_max_filesize => 2M => 2M

Restart http deamon usually using the command:
/etc/init.d/httpd restart

The global array $_COOKIE is used to retrieve the cookie value for subsequent page requests. Like...

<?php
$visits = 1;
if (isset($_COOKIE["visits"])) {
$visits = (int)$_COOKIE["visits"];
}
setcookie("visits", $visits + 1, time() + (60 * 60 * 24 * 30));
echo "You have visited this page $visits time(s).";

CURL can be used very effectively using PHP. Here is an example.

# cat curl.php
<?php
$ch = curl_init("http://www.google.com/");
$fp = fopen("example.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

Here is the code to show the files from the current directory.

<?php
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$thelist .= '<a href="'.$file.'">'.$file.'</a> <p> ';
}
}
closedir($handle);
}
?>
<P>List of files:</p>
<P><?=$thelist?></p>


I spent a lot of time figuring out how to upgrade my PEAR package.
The trick is to install the PEAR package with –force to make it go through

# pear upgrade --force PEAR

Just create a regular .PHP file, where you output your data in a nice little html-table. Then place the following snippet in the top of that file:

header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=excel.xls");

And it’s just that easy. If you open the page, you’ll see a download-window asking you where to place the file.

Open /etc/php.ini file
# vi /etc/php.ini
Set error_reporting as follows:

error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR

Alternately, you can show all errors, except for notices and coding standards warnings

error_reporting = E_ALL & ~E_NOTICE

Save and close the file. Restart apache web server:
# /etc/init.d/httpd restart
