一，三个函数，一个观念：函数都有输入输出。
１，获取资料表的函数getrows()：
<?
function getrows( $database, $query ) {
mysql_connect ("ftp", "root", "");
$db = mysql_select_db( $database );
if ( ! $db ) {
echo "礚猭秨币 kjsql 戈畐叫絋﹚眤竒ミ kjsql 戈畐!";
exit;
}
$rows = mysql_query( $query );
if ( ! $rows ) {
echo "sql 岿粇礚猭匡戈!";
exit;
}
return $rows;
}
?>
$rows是函数的输出，作为存取资料的依据。
２，连结数据库的函数connectdatabase():
<?php
function connectdatabase( $database ) {
mysql_connect ("ftp", "root", "");
$db = mysql_select_db( $database );
if ( ! $db ) {
echo "礚猭秨币 kjsql 戈畐叫絋﹚眤竒ミ kjsql 戈畐!";
exit;
}
}
?>
３，显示一页的函数showonepage():
<?
function showonepage( $rows, $no ) {
mysql_data_seek( $rows, $no );
echo "<table border=1 align=center>";
echo "<tr bgcolor=cyan><td>no.</td>";
while ( $field = mysql_fetch_field($rows) ) {
echo "<td>" . $field->name . "</td>";
}
echo "</tr>";
for ( $i=1; $i <= 10; $i++ ) {
if ( $row = mysql_fetch_row($rows) ) {
echo "<tr><td align=right>" . ($no + $i) . "</td>";
for ( $k=0 ; $k < count($row); $k++ ) {
echo "<td align=right>" . $row[$k] . "</td>";
}
echo "</tr>";
}
}
echo "</table>";
}
?>
输出为一张表格。
二，分页的技巧
version１，只显示１到１０条记录：
<?
function showonepage( $rows, $no ) {
mysql_data_seek( $rows, $no );
echo "<table border=1 align=center>";
echo "<tr bgcolor=cyan><td>no.</td>";
while ( $field = mysql_fetch_field($rows) ) {
echo "<td>" . $field->name . "</td>";
}
echo "</tr>";
for ( $i=1; $i <= 10; $i++ ) {
if ( $row = mysql_fetch_row($rows) ) {
echo "<tr><td align=right>" . ($no + $i) . "</td>";
for ( $k=0 ; $k < count($row); $k++ ) {
echo "<td align=right>" . $row[$k] . "</td>";
}
echo "</tr>";
}
}
echo "</table>";
}
?>
<html>
<body bgcolor="#ffffff">
<h2 align=center>pagev1.php3, version 1 - だмォ<hr></h2>
<?
include("../db.func");
$rows = getrows( "kjsql", "select * from stock" );
showonepage( $rows, 0 );
?>
<hr>
</body></html>
相关说明：1,$no参数，由于显示某一页，利用此参数指定该页的第一笔资料；
2,设定目前资料录的位子：mysql_data_seek($rows,$no);
3,判断是否还有资料录：if ($row=mysql_fetch_row($rows)).
version2，可以在ie位置栏输入页次：
<?
function showonepage( $rows, $no ) {
mysql_data_seek( $rows, $no );
echo "<table border=1 align=center>";
echo "<tr bgcolor=cyan><td>no.</td>";
while ( $field = mysql_fetch_field($rows) ) {
echo "<td>" . $field->name . "</td>";
}
echo "</tr>";
for ( $i=1; $i <= 10; $i++ ) {
if ( $row = mysql_fetch_row($rows) ) {
echo "<tr><td align=right>" . ($no + $i) . "</td>";
for ( $k=0 ; $k < count($row); $k++ ) {
echo "<td align=right>" . $row[$k] . "</td>";
}
echo "</tr>";
}
}
echo "</table>";
}
?>
<html>
<body bgcolor="#ffffff">
<h2 align=center>pagev2.php3, version 2 - だмォ<hr></h2>
<?
include("../db.func");
$rows = getrows( "kjsql", "select * from stock" );
$num = mysql_num_rows($rows);
$pages = intval(($num - 1) / 10) + 1;
if ( $page < 1 ) $page = 1;
if ( $page > $pages ) $page = $pages;
showonepage( $rows, ($page-1)*10 );
?>
<hr>
<div align=right>
ω:<font color=red><?echo $page;?>/<?echo $pages;?>
</div>
</body></html>
version３，页次的浏览：
<?
function showonepage( $rows, $no ) {
mysql_data_seek( $rows, $no );
echo "<table border=1 align=center>";
echo "<tr bgcolor=cyan><td>no.</td>";
while ( $field = mysql_fetch_field($rows) ) {
echo "<td>" . $field->name . "</td>";
}
echo "</tr>";
for ( $i=1; $i <= 10; $i++ ) {
if ( $row = mysql_fetch_row($rows) ) {
echo "<tr><td align=right>" . ($no + $i) . "</td>";
for ( $k=0 ; $k < count($row); $k++ ) {
echo "<td align=right>" . $row[$k] . "</td>";
}
echo "</tr>";
}
}
echo "</table>";
}
?>
<html>
<body bgcolor="#ffffff">
<h2 align=center>pagev3.php3, version 3 - ω聅凝<hr></h2>
<?
include("../db.func");
$rows = getrows( "kjsql", "select * from stock" );
$num = mysql_num_rows($rows);
$pages = intval(($num - 1) / 10) + 1;
if ( $page < 1 ) $page = 1;
if ( $page > $pages ) $page = $pages;
showonepage( $rows, ($page-1)*10 );
?>
<hr>
<div align=right>
<?
if ( $page <> 1 ) { // 狦ぃ琌材
echo "<a href=$php_self?page=1>材</a>";
echo "<a href=$php_self?page=" . ($page-1) . "></a>";
}
if ( $page <> $pages ) { // 狦ぃ琌程
echo "<a href=$php_self?page=" . ($page+1) . "></a>";
echo "<a href=$php_self?page=$pages>程</a>";
}
?>
ω:<font color=red><?echo $page;?>/<?echo $pages;?>
</div>
</body></html>
version 4，完成版：
<?
function showonepage( $rows, $no ) {
mysql_data_seek( $rows, $no );
echo "<table border=1 align=center>";
echo "<tr bgcolor=cyan><td>no.</td>";
while ( $field = mysql_fetch_field($rows) ) {
echo "<td>" . $field->name . "</td>";
}
echo "</tr>";
for ( $i=1; $i <= 10; $i++ ) {
if ( $row = mysql_fetch_row($rows) ) {
echo "<tr><td align=right>" . ($no + $i) . "</td>";
for ( $k=0 ; $k < count($row); $k++ ) {
echo "<td align=right>" . $row[$k] . "</td>";
}
echo "</tr>";
}
}
echo "</table>";
}
?>
