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>";
}
?>
