For example you want to echo several part of strings, usually we use this
<?php echo ‘hello ‘.’ world ‘.$name; ?>

Here is a little PHP cheat from me

To generate an array of (’a', ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’), you only need to do this :
<?php $array_of_char = str_split('abcdefg'); ?>

To generate an array of (1, 2, 3, 4, 5, 6, 7, 8, 9), you only need to do this
<?php $array_of_num = range(1, 9); ?>

Now cheating is fun ( cheating in PHP of course )

Usually we have edit and insert page for administration area.

While constructing the SQL query for editing and inserting for a same table with lots of fields may consume lot of time, why don’t we make it easier ?

So i create this class to help you with construction the SQL query for editing and inserting data.

Here’s the example usage of editing query

$dh = new dbhelper();
$dh->table_name = 'bet_type';
$dh->setFields(
   array('name' => 'bet_type_name', 'value' => $bt_name),
   array('name' => 'minimum_bet', 'value' => $bt_minimum_bet, 'type' => 'int'),
   array('name' => 'maximum_bet', 'value' => $bt_maximum_bet, 'type' => 'int'),
   array('name' => 'prize_percentage', 'value' => $bt_prize_percentage, 'type' => 'int'),
   array('name' => 'choice_length', 'value' => $bt_choice_length, 'type' => 'int'),
   array('name' => 'bet_note', 'value' => $bt_note),
   array('name' => 'bet_link_note', 'value' => $bt_link_note),
   array('name' => 'bet_type_status', 'value' => $bt_status),
   array('name' => 'sort_order', 'value' => $bt_sort_order, 'type' => 'int')
);
$q = $dh->sqlUpdate();
mysql_query($q);

I created a function recently. This function will insert random hidden spans between e-mail address that wil be displayed to the user. The purpose is to protect the e-mail from the crawler. I know this function may be does not powerful enough to prevent crawlers. By the way here is the function

/**
* Randomize email, insert hidden span randomly between e-mail address
* to prevent crawler.
*
* @arg        string    $email    the e-mail
* @return    string    scrambled e-mail (with HTML code)
*/
function randomizeEmail($email) {
	$s = $email;
	if ($email != '') {
		$s = '';
		$length = strlen($email);
		$random = str_split($email, ceil($length / mt_rand(2, ceil(0.8 * $length))));
		foreach ($random as $r) {
			$s .= $r.'<span style="display:none">'.md5(microtime()).'</span>';
		}
	}
	return $s;
}
