PEAR setup in WAMP in simple steps

Last updated: February 27th, 2013

* After WAMP is installed go to the folder where the web server related PHP bin directory is present. Search for the batch file pear.bat in it. Double click the file to start the PEAR installation. Go with the defaults and complete the installation

* Search for PEAR_ENV.reg. Double click that file to register the PEAR settings as environment variable

* Go to the command prompt and type “pear list” to see what packages are installed and if PEAR is correctly installed. If PEAR cannot be accessed via the command line, it means the PATH setting is not set correctly. Environment PATH variable should include the path to where pear.bat is present

RFC 3339 date format in RSS Feeds

Last updated: August 13th, 2012

RSS Feeds use RFC 3339 date format in their XML/Atom feeds.

Date formats have often caused confusion in the development, interoperability and maintenance of software applications. To improve the consistency in use of Date and Time, RFC 3339 came into existence which uses Coordinated Universal Time (UTC).

For PHP versions < 5.2,


$dateRFC = "2008-12-01T13:30:00.000-04:00";
$myDate = date('d.m.Y', strtotime($dateRFC)); // 01.12.2008

For PHP versions >= 5.2,


$dateRFC = "2008-12-01T13:30:00.000-04:00";
$myDate = new DateTime($dateRFC);
$dateStr = date('d.m.Y', strtotime($dateRFC)); // 01.12.2008

How to configure Zend Framework in windows?

Last updated: May 29th, 2011

Steps to configure Zend Framework in windows

i) Check if the path to PHP executable is set. You can check this by executing php -version from command prompt.

ii) Move zf.bat (or zf.sh) and zf.php which will be present in the Zend Framework’s bin folder to the php’s bin folder (where php.ini resides)

iii) Move \path\to\znedframework\library to the location identified by “include_path” variable

One way to identify the include_path variable
-> php -i

Other way is to open the php.ini file to identify the location. You can also append the path to zend framework’s library to the include path variable within php.ini file.

For Windows users, you can add an environment variable (system variable) that would point to the Zend Framework’s library folder and name the variable “ZEND_TOOL_INCLUDE_PATH”

If the configuration has been done correctly then you should be able to get a positive response when you execute

-> zf show version
-> zf –help

PHP: ‘Fatal error: Allowed memory size of 8388608 bytes exhausted’

Last updated: December 30th, 2010

Reason why you see this message is due to PHP memory leakage. PHP is trying to load a large image or file into memory and is not finding enough space for it to load.

If you think, that you will need the necessary feature to upload large files then there are two ways by which you can enable this feature.

i) Edit the physical file and have the line
ini_set(“memory_limit”,”20M”);

ii) Edit php.ini and add the following line. You need to restart the apache/IIS server once php.ini file is modified.
memory_limit=32M
