Install Imagemagick / Imagick for PHP on CentOS Cpanel/Plesk

Solution : For installing Imagick extension for PHP you have to install ImageMagick from source and Its a Must. Otherwise the extension for PHP wont compile.

*# wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz*
# tar zxf ImageMagick.tar.gz
# cd ImageMagick-x.x.x
# ./configure
# make
# make install

Now download the Imagick extension source from http://pecl.php.net/package/imagick

*# wget http://pecl.php.net/get/imagick-x.x.x.tgz*
# tar zxf imagick-x.x.x.tgz
# cd imagick-x.x.x.tgz
# phpize && ./configure

*** if you get an error which looks like this:

Solution : Install ImageMagick-devel package using “yum install ImageMagick-devel” and then continue

# make
# make install

This will make compile imagick source and build imagick.so - In my machine, I found imagick.so in the following directory

Installing shared extensions: /path/to/php/modules/

# Now add “extension=imagick.so” in your php.ini (You may need to write the full path of imagick.so based on your configuration)

# Restart your web server and thats it (You should see the Imagick extension section in phpinfo page )

Using php mail() function to send emails from php script.

Send Email from a PHP Script Example :

The first argument to this function is the recipient, the second specifies the message’s subject and the third one should contain the body. So to send a simple sample message, we could use:

$to = "recipient@example.com";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";
if (mail($to, $subject, $body)) {
echo("

Message successfully sent!

“);
} else {
echo(”

Message delivery failed…

“);
}
?>

Save this file as mail.php and browse from url http://yourdomain/mail.php

Q) All my other IMAP clients can connect to my server, but TWIG says:
Warning: Couldn’t open stream {localhost:143}INBOX in
/var/www/html/twig/lib/mail/php-imap.inc.php3

A) Your server probably has Transport Layer Security turned on, but
PHP does not support TLS. You’ll need to edit config.inc.php3:
$config[”imap_port”] = “143/notls”;

I came across wonderfull mysql quota check tool — Here is how it works -

The MySQL Quota-Tool helps you to set a size limit on MySQL databases.

It works by checking the size of each database and revoking the INSERT- and REATE-priveleges for the databases, which exceed the given size limit.

When the size of the database falls below the given limit, the INSERT- and CREATE-priveleges are granted again.

This (of course) doesn’t work for users who have global priveleges, because the quota is database and not user based, but in most environments privileges are given in the “db”-table which is modified by the MySQL Quota Tool.

#!/usr/bin/php -q


/*
* MySQL quota script
* written by Sebastian Marsching

I am going to install this tool and see how it works for me

The PHP Extension Community Library (PECL) is a collection of modules/extensions that you can install to enhance your version of PHP. The categories range wildly from Authentication to Image Handling, and from Encryption to XML. However, installation of the PECL libraries can sometimes be a bit tricky for the beginner. There are two main ways to install the PECL libraries. Note that if you installed PHP from an RPM or similar package, you will also need the PHP-devel package as well.

You can view all the PECL modules available at the PECL website. Some useful modules are:

• ImageMagick
• GDChart More info on using GDChart can be found here.
• ID3
• Mailparse

We will be installing Fileinfo 1.0.4 for this tutorial.

Installation using the PECL binary

If you are using a more recent version of PHP, chances are you have the pecl binary installed as well. As root from the command line, try running ‘pecl’. If found, it will give you a list of options that can be used to compile your extensions. To install Fileinfo, simply type

pecl install fileinfo

This will download the fileinfo source files, phpize the source, and then compile and install the extension.

You will need to activate the extension by editting your php.ini and add:

extension=fileinfo.so

Restarting your webserver should result in PHP starting with the fileinfo extension active and ready for use.

Installing from Source

Some systems don’t have pecl available due to running an older version of PHP. However, you can still install the extension, albeit with a bit more work. The first step is to download the extension, unpack the file, and phpize the contents. You then need to perform a normal configure and make routine to install the module:

wget http://pecl.php.net/get/Fileinfo-1.0.4.tgz
tar -zxf Fileinfo-1.0.4.tgz
cd Fileinfo-1.0.4
phpize
./configure
make
make install


This will install the fileinfo.so module in your php extensions folder. As per above, add this to your php.ini file by adding

extension=fileinfo.so

in the extensions section. It would be wise to check that your php.ini has the correct extensions directory set as well and this is set via the extension_dir directive.

Installing on Windows

Installation of the PECL modules on windows is alot easier, as all the hard work has been done. Simply locate the extension on the PECL Windows page and simply place the dll in your extensions directory. Add the extension to the php.ini file as described above, restart your web server, and you are good to go!

PEAR Is short for ‘PHP Extension and Application Repository’

PEAR is having it’s primary goal to become a repository for PHP extensions and library code. The most important goal of the PEAR project is to try to define standard coding packages that can be used be developers directoly and it is re-usable coding.
Each package is a seperate project and is having a diffreent developer team.

Packages are in the gzipped tar files with a description file inside, and installed on your server using the PEAR installer.

You can install any pear package as
———–
pear install pear-package-name
———–

You can check all the PEAR packages that are available with
————
pear list-all
————

You can check installed PEAR packages on your server as
————
pear list
