Here I write some notes about setting in php.ini. A little changes will make work easier and lazier.

1. pre-requirements After install PHP env XAMPP, we can find where is the key configure file: php.ini:

• http://localhost/xampp/phpinfo.php
• or command line: $ php —ini

All the following are from php.ini. Change some configures will make work easier and lazier.

2. Use instead of

For print a variable, use instead of seems a better point. Use of this shortcut requires short_open_tag to be on.

; This directive determines whether or not PHP will recognize ; code between tags as PHP source which should be processed as such. ; http://php.net/short-open-tag short_open_tag = on

3. make available ‘tail -f ’ $apache/logs/error.log.

; Besides displaying errors, PHP can also log errors to locations ; such as a server-specific log, STDERR, or a location specified ; by the error_log directive found below. ; http://php.net/log-errors log\errors = On_

4. include_path not working?

PEAR library is default included in XAMPP, so from: http://localhost/xampp/pearinfo.php we can get all PEAR info.

Right now suppose we want to code by using MDB2 package, like this:

require_once ‘MDB2.php’; $dsn = ‘mysql://test:test@localhost/test’; $mdb2 =& MDB2::factory($dsn); if (PEAR::isError($mdb2)) { echo ($mdb2->getMessage().’-‘.$mdb2->getUserinfo()); } …

When running, there is always error: Fatal error: Class ‘MDB2’ not found in …

It should be error regarding on path, because we already have PEAR. Check php.ini:

; PHP’s default setting is ”.;/path/to/php/pear” ; http://php.net/include-path include_path = ”.;C:xamppphpPEAR”

It looks correct: PEAR is already in the include_path. However, if we use:

print_r(get_included_files()); echo ”
n”;

or:

set_include_path(get_include_path()); ini_set(‘include_path’, ‘C:xamppphpPEARMDB2.php’); print_r(get_included_files()); echo ”
n”;

to test, the error is still there, the adding don’t work.

The reason: the ’.;’ at the beginning of include_path setting is not working. They display in phpinfo(), but not active in codes.

So remove it, and change the setting like this:

include_path = “C:xamppxamppphpPEAR”

Right now re-run the codes, it works. This is only applicable in Windows env; if in Linux, it works fine.
