用PHP调用Oracle存储过程
PHP程序访问数据库,完全可以使用存储过程,有人认为使用存储过程便于维护
不过仁者见仁,智者见智,在这个问题上,偶认为使用存储过程意味着必须要DBA和开发人员更紧密配合,如果其中一方更变,则显然难以维护。
但是使用存储过程至少有两个最明显的优点:速度和效率。
使用存储过程的速度显然更快。
在效率上,如果应用一次需要做一系列SQL操作,则需要往返于PHP与ORACLE,不如把该应用直接放到数据库方以减少往返次数,增加效率。
但是在INTERNET应用上,速度是极度重要的,所以很有必要使用存储过程。
偶也是使用PHP调用存储过程不久,做了下面这个列子。
代码:--------------------------------------------------------------------------------
//建立一个TEST表
CREATE TABLE TEST (
ID NUMBER(16) NOT NULL,
NAME VARCHAR2(30) NOT NULL,
PRIMARY KEY (ID)
);
//插入一条数据
INSERT INTO TEST VALUES (5, 'PHP_BOOK');
//建立一个存储过程
CREATE OR REPLACE PROCEDURE PROC_TEST (
p_id IN OUT NUMBER,
p_name OUT VARCHAR2
) AS
BEGIN
SELECT NAME INTO p_name
FROM TEST
WHERE ID = 5;
END PROC_TEST;
/
--------------------------------------------------------------------------------
PHP代码:--------------------------------------------------------------------------------
//建立数据库连接
$user = "scott"; //数据库用户名
$password = "tiger"; //密码
$conn_str = "tnsname"; //连接串(cstr : Connection_STRing)
$remote = true //是否远程连接
if ($remote) {
$conn = OCILogon($user, $password, $conn_str);
}
else {
$conn = OCILogon($user, $password);
}
//设定绑定
$id = 5; //准备用以绑定的php变量 id
$name = ""; //准备用以绑定的php变量 name
/** 调用存储过程的sql语句(sql_sp : SQL_StoreProcedure)
* 语法:
* BEGIN 存储过程名([[:]参数]); END;
* 加上冒号表示该参数是一个位置
**/
$sql_sp = "BEGIN PROC_TEST(:id, :name); END;";
//Parse
$stmt = OCIParse($conn, $sql_sp);
//执行绑定
OCIBindByName($stmt, ":id", $id, 16); //参数说明:绑定php变量$id到位置:id,并设定绑定长度16位
OCIBindByName($stmt, ":name", $name, 30);
//Execute
OCIExecute($stmt);
//结果
echo "name is : $name
";
?>

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
