PHP: NotORM tutorial

Here is a nice tutorial of: http://www.sitepoint.com/database-interaction-made-easy-with-notorm/

fatfree: error routing about in tutorial

following this tutorial : http://fatfreeframework.com/routing-engine, after adding

$f3->route('GET /about','WebPage->display');

the url localhost/myproject/ works fine, but localhost/myproject/about doesnt work.

To solve the problem, follow these steps:

1. create a file name .htaccess with the following content:

# Enable rewrite engine and route requests to framework
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php [L,QSA]

# Disable ETags
<IfModule mod_headers.c>
Header Unset ETag
FileETag none
</IfModule>

# Default expires header if none specified (stay in browser cache for 7 days)
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault A604800
</IfModule>

2. put the .htaccess file in the root of wour project, ie {apacheserverdir}\htdocs\pyproject\.htaccess

The error happens because is missing the .htaccess file in the right place:

\htdocs\myproject
\htdocs\myproject\.htaccess -- add htaccess file here
\htdocs\myproject\index.php
\htdocs\myproject\libs
\htdocs\myproject\libs\fatfree-master
......
\htdocs\myproject\libs\fatfree-master\.htaccess -- here is a htaccess file that is not used at all
......
\htdocs\myproject\libs\fatfree-master\lib
\htdocs\myproject\libs\fatfree-master\lib\audit.php
\htdocs\myproject\libs\fatfree-master\lib\auth.php
\htdocs\myproject\libs\fatfree-master\lib\base.php
......
......
.....

PHP: Unable to load dynamic library 'php_oci8.dll' , the procedure entry point ocilobread2 could not be located

Situation:

The Apache service wasn't starting

in the Apache error.log file I was getting the following error:

"Warning: PHP Startup: Unable to load dynamic library 'C:/php/ext/php_oci8.dll' - The specified procedure could not be found. \r \n in Unknown on line 0"

the I tried to execute from windows console the php command and I got the following error in an emerging window:

"the procedure entry point ocilobread2 could not be located in the dynamic link library oci.dll"

And also, in the PHP console, I got the error that I mentioned in the beginning of this post : "... Unable to load dynamic library .... "

Solution:

- download and unzip instantclient_10_2

- set PATH variable with the instantclient_10_2 folder route ie (C:\instantclient_10_2) . Note: Is VERY important that the instantclient path must be added at beginning of PATH variable or VERIFY the PATH variable in order to avoid having other routes to a different instanclient.

- check up php command in console

- restart APACHE
