API functions


If you were going to separate code PHP from HTML a code, you have two variants. One way - creation of functions of dynamic formation of a conclusion and to place them in the necessary place on web - page.


For example, so:


index.php - a code of page



<? php include_once ("site.lib");?>

<html>

<head>

<title> <? php print_header ();?> </title>

</head>

<body>

<h1> <? php print_header ();?> </h1>

<table border = "0" cellpadding = "0" cellspacing = "0">

<tr>

<td width = " 25 % ">

<? php print_links ();?>

</td>

<td>

<? php print_body ();?>

</td>

</tr>

</table>

</body>

</html>


site.lib - the code of the program



<? php


$dbh = mysql_connect ("localhost", "sh", "pass")

or die (sprintf (" I can not open connection with MySQL [%s]: %s ",

mysql_errno (), mysql_error ()));


@mysql_select_db ("MainSite")

or die (sprintf (" I can not choose a database [%s]: %s ",

mysql_errno (), mysql_error ()));


$sth = @mysql_query (" SELECT * FROM site ", $dbh)

or die (sprintf (" I can not execute search [%s]: %s ",

mysql_errno (), mysql_error ()));


$site_info = mysql_fetch_object ($sth);


function print_header ()

{

global $site_info;

print $site_info-> header;

}


function print_body ()

{

global $site_info;

print nl2br ($site_info-> body);

}


function print_links ()

{

global $site_info;


$links = explode ("n", $site_info-> links);

$names = explode ("n", $site_info-> link_names);


for ($i = 0; $i <count ($links); $i ++)

{

print " ttt

<a href = " $ links [$i] "> $names [$i] </a>

n <br> n ";

}

}

?>


Obviously, such code is better readable. One more advantage of use of this concept - an opportunity of change of design without updating the code of the program.


Pluss of use API of functions


* Rather pure{clean}, clear code

* A fast code
