Installing PEAR for PHP
Installation
For Windows:
- To update your PEAR installation, request http://pear.php.net/go-pear in your browser and save the output to a local file go-pear.php.
- Assuming you have installed PHP already, and it is runnable from the command line type php go-pear.php
For FreeBSD:
- Add the PEAR DB package from the ports /usr/ports/databases/pear-DB
Test Installation
To make sure that PEAR is working simply type in pear at the command prompt. If nothing shows then check that the PEAR path is part of your system path. Check the version of PEAR by typing pear version
To use PEAR and PEAR compatible packages in your applications, you normally include them into your PHP scripts using require_once(). For this to work, PEAR’s php_dir must be a part of PHP’s include path.
First check where PEAR installs php files by typing
pear config-get php_dir
Whatever the folder is, this folder will contain System.php
To find which configuration file is used by your PHP installation. On command line, execute php –ini
When you execute a phpinfo() in the browser it should always the show the PEAR path in its include path for the PEAR packages to work.

$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $image_url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
// Getting binary data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$image = curl_exec($ch);
curl_close($ch);
// write to local file
$f = fopen(’/home/www/path/image.jpg’, ‘w’);
fwrite($f, $image);
fclose($f);
// output to browser
header(”Content-type: image/jpeg”);
print $image;
?>
There is a very simple way of doing this. We use the find command to get all the s/.v .svn folders in a folder. The next step is to pass the output of this command to the delete command .
So to list all .svn folders in the current folder:
Next pass the output of this to the rm command by enclosing the find command in accented single quotes:

Recovering from a corrupt rc.conf
Sometimes we may make a mistake in the rc.conf file - either a syntax error or loading something which causes the system to crash. In such a case we need to fix the rc.conf file so that the system can boot normally.
The steps to do this are given below:
- Boot into single user mode
- When prompted for a shell pathname, press Enter
- Type mount -urw / to re-mount the root file system in read/write mode.
- Type mount -a -t ufs to mount the current file system so that you can runyour preferred editor eg. vi
- Edit /etc/rc.conf as required and save it
- Restart the system
If after installing Apache and starting the server the following message shows in the error logs and the apache server does not start:
hostname nor servname provided, or not known: mod_unique_id: unable to find IPv4 address of xxxxxx
then in httpd.conf disable the line
LoadModule unique_id_module libexec/apache2/mod_unique_id.so
Restart again. This is usually the fix if changing hosts and httpd.conf ServerName entries etc. do not fix the problem.

Installing Mysql 5.x
The commands are given below. Though this was used to install mysql 5.5.4 , it is applicable to older versions also (and perhaps newer ones as well).
cd /usr/ports/databases/mysql55-server/
make install clean
/usr/local/bin/mysql_install_db
chown -R mysql /var/db/mysql/
chgrp -R mysql /var/db/mysql/
/usr/local/bin/mysqld_safe –user=mysql &
/usr/local/bin/mysqladmin -u root password newpassword
Edit /etc/rc.conf to start mysql server at startup by putting the line
mysql_enable=”YES”
After this, restart FreeBSD.
