Here are a few I use a lot. Not mine, but found them on various websites.
MySQL to PHP datetime converter:
PHP Code:
function datetime($syntax,$datetime)
{
$year = substr($datetime,0,4);
$month = substr($datetime,5,2);
$day = substr($datetime,8,2);
$hour = substr($datetime,11,2);
$min = substr($datetime,14,2);
$sec = substr($datetime,17,2);
return date($syntax,mktime($hour,$min,$sec,$month,$day,$year));
}
Escape Data:
PHP Code:
function escape_data($data)
{
global $con;
if (ini_get('magic_quotes_gpc'))
{
$data = stripslashes($data);
}
return mysql_real_escape_string(trim($data), $con);
}
Validate E-Mail Address:
PHP Code:
function validateEmail($email)
{
// First, we check that there's one @ symbol, and that the lengths are right
if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email))
{
// Email invalid because wrong number of characters in one section, or wrong number of @ symbols.
return false;
}
// Split it into sections to make life easier
$email_array = explode("@", $email);
$local_array = explode(".", $email_array[0]);
for ($i = 0; $i < sizeof($local_array); $i++)
{
if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i]))
{
return false;
}
}
if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1]))
{
// Check if domain is IP. If not, it should be valid domain name
$domain_array = explode(".", $email_array[1]);
if (sizeof($domain_array) < 2)
{
return false; // Not enough parts to domain
}
for ($i = 0; $i < sizeof($domain_array); $i++)
{
if (!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$", $domain_array[$i]))
{
return false;
}
}
}
return true;
}
