MySQL's built-in string-related functions can be used severalways You can use functions in SELECT statements without

specifying a table to retrieve a result of the function Or you canuse functions to enhance your SELECT results by concatenatingtwo fields to form a new string

Even if you never use these functions in your applications, it'sgood to know they exist, and, if nothing else, you'll get somegood practice in this hour using the MySQL monitor's command-line interface

Length and Concatenation Functions

The group of length and concatenation functions focuses on thelength of strings and concatenating strings together Length-related functions include LENGTH(), OCTET_LENGTH(),

CHAR_LENGTH(), and CHARACTER_LENGTH(), which do

strings, use two field names to concatenate the firstname and

the lastname fields By concatenating the fields, you reduce

the lines of code necessary to achieve the same result in your

application:

mysql> select concat(firstname, lastname) from table_name; + -+

mysql> select trim(trailing 'X' from 'XXXneedleXXX'); + -+

Just like RTRIM() and LTRIM() remove padding characters,

RPAD() and LPAD() add characters to a string For example,

and length, you can use the SUBSTRING() function This

example gets three characters from the string MySQL, starting

at position 2:

mysql> select substring("MySQL", 2, 3);

+ -+

XXXX-YYYYY-ZZ, you can use substring functions to extract the

individual parts of the whole For example, if ZZ always

represents the state to which the order was shipped, you can

| mysql | + -+

1 row in set (0.00 sec)

mysql> select ucase('mysql');

+ -+

| UCASE(' mysql') | + -+

| MYSQL | + -+

+ -+

BIN(), OCT(), and HEX() functions do not require a table

selection but return values without a specified table

The following example gets a string representation of the binaryvalue of the integer 56895:

1 row in set (0.00 sec)

You can also use the CONV() function to convert numbers

between bases This function has three parts: the number, thebase you're converting from, and the base you're converting to

Until now, we have simply printed any strings that we want todisplay directly to the browser PHP provides two functions thatallow you first to apply formatting, whether to round doubles to

a given number of decimal places, define alignment within afield, or display data according to different number systems Inthis section, you will look at a few of the formatting optionsprovided by printf() and sprintf()

snippet, for example, uses printf() to output an integer as adecimal:

printf() You can include as many conversion specifications

send an equivalent number of arguments to printf()

The following snippet outputs two numbers using printf():

printf("First number: %d<br>\nSecond number: %d<br>\n", 55, 66); // Output:

be padded to two characters, which would become a problem if

we changed our $red, $green, and $blue variables in thepreceding snippet to contain 1, for example We would end upwith the output "#111" You can force the output of leadingzeros by using a padding specifier

Padding Output with the Padding Specifier

You can require that output be padded by leading characters.The padding specifier should directly follow the percent signthat begins a conversion specification To pad output with

leading zeros, the padding specifier should consist of a zerofollowed by the number of characters you want the output totake up If the output occupies fewer characters than this total,the difference will be filled with zeros:

printf( "%04d", 36 );

// prints "0036"

To pad output with leading spaces, the padding specifier shouldconsist of a space character followed by the number of

// prints "xx36"

We now have the tools we need to complete our HTML codeexample Until now, we could convert three numbers, but wecould not pad them with leading zeros:

$red = 1;

$green = 1;

$blue = 1;

printf( "#%02X%02X%02X", $red, $green, $blue ); // prints "#010101"

Each variable is output as a hexadecimal number If the outputoccupies fewer than two spaces, leading zeros will be added

Specifying a Field Width

You can specify the number of spaces within which your outputshould sit The field width specifier is an integer that should beplaced after the percent sign that begins a conversion

printf("%-20s\n", "Left aligned");

Note that alignment applies to the decimal portion of any

Specifying Precision

If you want to output data in floating-point format, you can

specify the precision to which you want to round your data Thiscapability is particularly useful when you are dealing with

currency The precision identifier should be placed directly

before the type specifier It consists of a dot (.) followed by thenumber of decimal places to which you want to round This

it is difficult to use both a padding specifier and a field widthspecifier You should choose to use one or the other, but notboth

6: <body>

7: <?php

8: $products = array("Green armchair"=>222.4, 9: "Candlestick"=>"4",

10: "Coffee table"=>80.6

11: );

12: print "<pre>";

13: printf("%-20s%23s\n", "Name", "Price");

15: foreach ($products as $key=>$val) {

16: printf( "%-20s%20.2f\n", $key, $val ); 17: }

printf() call on line 13 defines the following format controlstring:

"%-20s%23s\n"

The first conversion specification ("%-20s") uses a field widthspecifier of 20 characters, with the output left-justified We use

function call on line 14 draws a line of -string

The final printf() call on line 16 is part of a foreach

statement that loops through our product array We use twoconversion specifications The first ("%-20s") prints the

product name as a string left-justified within a 20-characterfield The second conversion specification ("%20.2f") uses afield width specifier to ensure that output will be right-alignedwithin a 20-character field, and a precision specifier to ensurethat the double we output is rounded to two decimal places
