Dynamic PDF files using HTML and PHP

FPDF: The PDF Generator
The first and the main base for this file conversion is FPDF library. FPDF is a pure PHP class to generate PDF files on the fly. Let us start the PDF generation with a simple Hello world display.

$pdf=new FPDF();
$pdf->Cell(40,10,'Hello World!');

To generate a pdf file, first we need to include library file fpdf.php. Then we need to create an FPDF object using the default constructor FPDF(). This constructor can be passed three values namely page orientation (portrait or landscape), measure unit, and page size (A4, A5, etc.,). By default pages are in A4 portrait and the measure unit is millimeter. It could have been specified explicitly with:

$pdf=new FPDF('P','mm','A4');

It is possible to use landscape (L), other page formats (such as Letter and Legal) and measure units (pt, cm, in).

Then we have added a page to our pdf document with AddPage(). The origin is at the upper-left corner and the current position is by default placed at 1 cm from the borders; the margins can be changed with the function SetMargins().

To print a text, we need to first select a font with SetFont(). Let us select Arial bold 16:


We use Cell() function to output a text. A cell is a rectangular area, possibly framed, which contains some text. It is output at the current position. We specify its dimensions, its text (centered or aligned), if borders should be drawn, and where the current position moves after it (to the right, below or to the beginning of the next line). To add a frame, we would do this:

$pdf->Cell(40,10,'Hello World !',1);

Finally, the document is closed and sent to the browser with Output(). We could have saved it in a file by passing the desired file name.

MySql Teminal Commands

This is a list of handy MySQL commands that I use time and time again. At the bottom are statements, clauses, and functions you can use in MySQL. Below that are PHP and Perl API functions you can use to interface with MySQL. To use those you will need to build PHP with MySQL functionality.

Below when you see # it means from the unix shell. When you see mysql> it means from a MySQL prompt after logging into MySQL.
To login (from unix shell) use -h only if needed.

# [mysql dir]/bin/mysql -h hostname -u root -p
Create a database on the sql server.

mysql> create database [databasename];
List all databases on the sql server.

mysql> show databases;
Switch to a database.

mysql> use [db name];
To see all the tables in the db.

mysql> show tables;
To see database's field formats.

mysql> describe [table name];
To delete a db.

mysql> drop database [database name];
To delete a table.

mysql> drop table [table name];
Show all data in a table.

mysql> SELECT * FROM [table name];
Returns the columns and column information pertaining to the designated table.

mysql> show columns from [table name];
Show certain selected rows with the value "whatever".

mysql> SELECT * FROM [table name] WHERE [field name] = "whatever";
Show all records containing the name "ihsan" AND the phone number '3444444'.

mysql> SELECT * FROM [table name] WHERE name = "ihsan" AND phone_number = '3444444';
Show all records not containing the name "ihsan" AND the phone number '3444444' order by the phone_number field.

mysql> SELECT * FROM [table name] WHERE name != "ihsan" AND phone_number = '3444444' order by phone_number;
Show all records starting with the letters 'ihsan' AND the phone number '3444444'.

mysql> SELECT * FROM [table name] WHERE name like "ihsan%" AND phone_number = '3444444';
Show all records starting with the letters 'ihsan' AND the phone number '3444444' limit to records 1 through 5.

mysql> SELECT * FROM [table name] WHERE name like "ihsan%" AND phone_number = '3444444' limit 1,5;
Use a regular expression to find records. Use "REGEXP BINARY" to force case-sensitivity. This finds any record beginning with a.

mysql> SELECT * FROM [table name] WHERE rec RLIKE "^a";
Show unique records.

mysql> SELECT DISTINCT [column name] FROM [table name];
Show selected records sorted in an ascending (asc) or descending (desc).

mysql> SELECT [col1],[col2] FROM [table name] ORDER BY [col2] DESC;
Return number of rows.

mysql> SELECT COUNT(*) FROM [table name];
Sum column.

mysql> SELECT SUM(*) FROM [table name];
Join tables on common columns.

mysql> select lookup.illustrationid, lookup.personid,person.birthday from lookup left join person on lookup.personid=person.personid=statement to join birthday in person table with primary illustration id;
Creating a new user. Login as root. Switch to the MySQL db. Make the user. Update privs.

# mysql -u root -p
mysql> use mysql;
mysql> INSERT INTO user (Host,User,Password) VALUES('%','username',PASSWORD('password'));

Change a users password from unix shell.

# [mysql dir]/bin/mysqladmin -u username -h -p password 'new-password'
Change a users password from MySQL prompt. Login as root. Set the password. Update privs.

# mysql -u root -p
mysql> SET PASSWORD FOR 'user'@'hostname' = PASSWORD('passwordhere');
mysql> flush privileges;
Recover a MySQL root password. Stop the MySQL server process. Start again with no grant tables. Login to MySQL as root. Set new password. Exit MySQL and restart MySQL server.

# /etc/init.d/mysql stop
# mysqld_safe --skip-grant-tables &
