This article will introduce the paging function of the database implemented by PHP and orace database. Students in need can take a look below.

The code is as follows
 代码如下 复制代码




include "/maya/inc/dbconn.php";
$sql="select max(rownum) from xqhtest where id $stmt=ociparse($gConn,$sql);
ociexecute($stmt);
ocifetch($stmt);
$rowcount=ociresult($stmt,1);
ocifreestatement($stmt);
echo("共有".$rowcount."条记录
n");
$recordperpage=15; //每页显示多少条记录
$pages=ceil($rowcount/$recordperpage);  //总页数
echo("共有".$pages."页
n");

?>


//判断偏移量参数是否传递给了脚本,如果没有就使用默认值0

if (empty($offset))
{
    $offset=1;
}
$currentpage=ceil($offset/$recordperpage); //显示当前页
echo("当前页:".$currentpage."
n");
$endset=$offset+$recordperpage;

$stmt2=ociparse($gConn,"SELECT rownum,id,name FROM xqhtest WHERE id //echo "SELECT id,name FROM xqhtest WHERE rownumn";
ociexecute($stmt2);
//可以是任何sql语句,但select后面一定要有rownum,这是oracle特有的!
while (ocifetch($stmt2))

{
echo("

n");

   //换成你用于显示返回记录的代码
}
//要写出到所有页面的链接
print "

id name
".ociresult($stmt2,"ID")." ".ociresult($stmt2,"NAME")."


";


for ($i=1; $i {
  $newoffset=($recordperpage*($i-1))+1;
  print "$i n";
}
print "
";

$nextoffset=$recordperpage*$currentpage+1;
$prevoffset=$recordperpage*($currentpage-2)+1;
//判断是否需要上一页连接
if (($currentpage>1) && ($currentpage {
print "上一页 n";
}

Copy code

n");

?>

ociexecute($stmt2);
//It can be any SQL statement, but there must be rownum after select, which is unique to Oracle!
while (ocifetch($stmt2))
{
echo("
> ;n"); //Replace with the code you use to display the returned records
}
//To write links to all pages
print "
id name
".ociresult($stmt2,"ID")." ".ociresult($stmt2,"NAME")."


";
for ($i=1; $i {

}
print "
";
$nextoffset=$recordperpage*$currentpage+1;
$prevoffset=$recordperpage*($currentpage-2)+1;
//Determine whether a previous page connection is needed
if (($currentpage>1) && ($currentpage {
print "Previous page n";

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
