Grab a remote web document using sockets, with limited handling for 301 & 302 redirects.

This is a rewrite of a basic ADODB / PHP Database pager. This pager has some very slick search, sort, and display configuration options. Modifications and improvements are very welcome. Thus I am sharing this code.

A basic example for using this pager would be as follows:

// Check class code for CSS styles used
require_once ('class.init.php');

// SQL Statement
$sql = 'SELECT table1.field1, table1.field2, table1.field3 FROM table1';

// Field Labels
$label_arr = array (
'field1' => 'Field 1 Heading',
'field2' => 'Field 2 Heading',
'field3' => 'Field 3 Heading'
);

// Hidden Fields
$vsel_arr = array (
'field3' => 0 // don't display field3 unless requested by the user
);

$sort_arr = array (
'field1' => 'asc' // sort by field1 ascending order (asc) or (desc)
);

// Config array
$config = array (
'db' => &$dbconn, // open ADODB connection
'sql' => $sql, // String of sql
'id' => 'table1_pager', // pager id for session variables
'label_arr' => $label_arr, // field heading array
'vsel_arr' => $vsel_arr, // fields to hide
'extra_param' => '', // extra paramaters to pass with edit, delete, add anchors
'form_width' => '100%', // table with
'form_title' => 'Table 1', // table title
'edit_anchor' => 'Edit', // link to edit
'del_anchor' => 'Del', // link to delete
'add_anchor' => 'Add', // link to add
'print_anchor' => 'Print', // link to print
'header_view' => true, // no function at this time
'search_view' => true, // no function at this time
'pk' => array ('field1' => true), // primary key field
'sort_arr' => $sort_arr, // sort field array
);

// create object then render it ...
$_pager = new pager($config); // create instance
echo $_pager->render(25); // render output

This is a Tiny PHP Uploading script. It SHOULD be safe from both really large files and non-image files.

Get File Size

Change the case of an array.

This function simply splits a file based on the splitter supplied and returns an array with the values. It's pretty much like the file() function. This script could be helpful in section editings.

Genetic Algorithm implementation.

Based on "Random Password Generation"

This could be used for any type of simple hash checking. It could also be used to store a "password" that had to be verified. This code is completely managed.

Is this file the same as that file? The files may or may not be binary. We could compare the modify dates, or the sizes. But, those are not very accurate to know if a file has really changed.

Introducing MD5 Checksum. We can feed the files into Digest::MD5 in binary mode.

This is a great way to do Incremental Backups.

This is also an easy way to verify checksums when downloading files from the internet which list their MD5 Checksums.

You'll need the Digest::MD5 Perl Module.
