This article teaches you how to find absolute path using PHP. Open your notepad or any other text editor and put in the following PHP script:

<?php
$p = getcwd();
echo $p;
?>

Save the file as path.php (or first as txt and rename to info.php) and upload it to the root directory of your site through ftp. Run it as http://yoursite.com/path.php and you have your absolute path.

Hope this helps! :-)

To install, enable PHP cURL on XAMPP is really easy. All you have to do is to edit php.ini file, there are three php.ini files in your xampp folder, they are:

C:\Program Files\xampp\apache\bin\php.ini
C:\Program Files\xampp\php\php.ini
C:\Program Files\xampp\php\php4\php.ini

You really only have to edit one, which is C:\Program Files\xampp\apache\bin\php.ini.

1. Open the file in your text editor, and search for the line: ;extension=php_curl.dll

2. Uncomment it by removing the semicolon, so it should look like: extension=php_curl.dll

3. Save the file.

4. Restart your Apache Server.

Now you have cURL enabled.

If you try to upload Flash flv file using PHP, and the files are not uploaded, you may even have tried to edit php.ini file, and it still doesn’t work. The reason is simple, for most people who use xampp, the php.ini is not in php/php.ini or php/php5.ini. The file is inside apache/php.ini.

The easiest way to locate the right php.ini file is to write an php file with the code: phpinfo();

View the php file from your browser and search to find the word: php.ini. You should get the path now.

Open the php.ini file and search for the word upload_max_filesize and post_max_size, assign them with bigger values. For instance:

upload_max_filesize = 100M
post_max_size = 100M

If you have tried to increase the upload_max_filesize and post_max_size in the php.ini file and it still doesn’t work, don’t give up. The problem could lies somewhere else, it could because of directory permission.

Good luck with your uploading!

Use the following PHP function, you can display all image information (EXIF data) for a particular jpg file.

<?php
echo "aladdin-sane.jpg:<br />\n";
$exif = exif_read_data('david-bowie/aladdin-sane.jpg', 'IFD0');
echo $exif===false ? "No header data found.<br />\n" : "Image contains headers<br />\n";

$exif = exif_read_data('david-bowie/aladdin-sane.jpg', 0, true);
echo "test2.jpg:<br />\n";
foreach ($exif as $key => $section) {
foreach ($section as $name => $val) {
echo "$key.$name: $val<br />\n";
}
}
?>

A random password generator is a fairly common function used by PHP coded websites. The one below is what i use for many websites.

<?php
/**
* Random Password Generator
* @public
* @param int $length Length of password to generate
* @return string Returns randomised password
*/
function randomPword($length)
{
$seed = 'ABC123DEF456GHI789JKL0MNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
$seedLength = strlen($seed);
$random = '';
for ($i=1; $i <= $length; $i++)
{
$charPos = mt_rand(0, ($seedLength - 1));
$singleChar = substr($seed, $charPos, 1);
$random .= $singleChar;
}
return $random;
}
?>

Hope it helps! Enjoy!
