Compute Age in PHP

Code to compute age in PHP

<?php

  list($bYear, $bMonth, $bDay) = explode("-", $birthday);

  $cMonth = date('n');
  $cDay = date('j');
  $cYear = date('Y');

  if(($cMonth >= $bMonth && $cDay >= $bDay) || ($cMonth > $bMonth)) {
      $age = $cYear - $bYear;
  } else {
      $age = 0;
  }

  echo $age;
?>

The date format in the code above is yyyy-mm-dd.

If you are to use mm/dd/yyy format change the code

list($bYear, $bMonth, $bDay) = explode("-", $birthday);

list($bMonth, $bDay, $bYear) = explode("/", $birthday);

Instant Messaging in Nokia N95

I'm using Fring when instant messaging in my Nokia N95. It supports many protocols like Yahoo, Google Talk, Skype call in Fring.

Note: Install the application in your memory card so it won't be removed when updating your firmware.

Unable to set database connection charset: utf8 in CodeIgniter

If you have experiencing this error in CodeIgniter using CodeIgniter 1.6.x and MySQL 4.0

Unable to set database connection charset: utf8

It is setting the character set and collation for the database to which you are connecting.

A quick and dirty way of fixing this is looking for the db_set_charset() function on your system/database/drivers/your_driver/your_driver_driver.php


function db_set_charset($charset, $collation)
{
        return TRUE;
       //return @mysql_query("SET NAMES '".$this->escape_str($charset)."' COLLATE '".$this->escape_str($collation)."'", $this->conn_id);
}

A better fix


function db_set_charset($charset, $collation)
{
  if($charset == false || $collation == false)
  {
    return true;
  }
  else
  {
    return @mysql_query("SET NAMES '".$this->escape_str($charset)."' COLLATE '".$this->escape_str($collation)."'", $this->conn_id);
  }
}

Set the following in your database.php


$db['default']['char_set'] = false;
$db['default']['dbcollat'] = false;

Enabling cURL in XAMPP

Search for all the PHP ini files in the XAMMP directory including php4.ini/php5.ini

Look for the lines

;extension=php_curl.dll
;extension=php_openssl.dll

Uncomment the lines to enable the extension

extension=php_curl.dll
extension=php_openssl.dll

Restart Apache. To verify, you should see in the PHP info [phpinfo();] that cURL is enabled or you could try testing the following code


<?php

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://www.google.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$output = curl_exec($ch);

curl_close($ch);

$output = str_replace('Google', 'Test', $output);

echo $output;

?>

Posting source code on blogger

Download WebCodeFormatter which is Java application and paste you code in the window. Click Transform. Some characters that are converted are single and double quotes.

Sample code


if(!inWpsDir()) {
 $wps_dir = dirname(__FILE__);
 error_message("Please cd to the $wps_dir and run install.php");
 exit(1);
}
if($err = validate_php_env($reqd_wps_ext)) {
 error_message("Missing required PHP extention(s) for WPS Toolkit: $err");
 exit(1);
}

And you will see the this code converted to an acceptable format for blogger.
