php读取excel文件-reader.php excel操作类使用
?一、?概述 PHP-ExcelReader?是一个读取?Excel xsl?文件内容的一个?PHP?类。 它的下载网址:?http://sourceforge.net/projects/phpexcelreader/ 本博客下载地址:phpExcelReader.zip 测试用Excel文件:测试.xls 文件名:?phpExcelReader.zip 包含两个必需文件:?oleread.inc?、?reader.php?。其它文件是一个应用例子?,?自述文件等 ? 二、?文件使用 首先?,?包含?reader?类文件:?require_once " reader.php"; 新建一个实例:?$xl_reader= new Spreadsheet_Excel_Reader ( ); 设定编码信息: $xl_reader->setOutputEncoding('utf-8');//不设定可能会是乱码 要和网页显示编码一致 读取?Excel?文件信息:?$xl_reader->read("filename.xls"); ? 它将导出?Excel?文件中所有可以识别的数据存储在一个对象中。数据存储在?2?个数组中,目前没有提供方法?/?函数访问这些数据?.?可以像下面这样简单的使用数组名。 ? sheets?数组包含了读取入对象的大量数据。它将导出?Excel?文件中所有可以识别的数据存储在一个?2?维数组中?$xl_reader->sheets[x][y]?。?x?为文档中的表序号,?y?是以下的某个参数?: ①??????? numRows -- int --?表的行数 例如:?$rows = $xl_reader->sheets[0]['numRows'] ②??????? numCols -- int --?表的列数 例如:?$cols = $xl_reader->sheets[0]['numCols'] ③??????? cells -- array --?表的实际内容。是一个?[row][column]?格式的?2?维数组 ??例如:?$cell_2_4 = $xl_reader->sheets[0]['cells'][2][4] //?行?2,?列?4?中的数据 ④??????? cellsInfo -- array --?表格中不同数据类型的信息。每个都包含了表格的原始数据和类型。这个数组包含?2?部分:?raw --?表格原始数据;?type --?数据类型。 注:只显示非文本数据信息。 例如:?$cell_info = $xl_reader[0]['cellsInfo'][2][4] $cell_info['raw'] is the raw data from the cell $cell_info['type'] is the data type ? $xl_reader->sheets?数组示例:
Array( [0] => Array ( [maxrow] => 0 [maxcol] => 0 [numRows] => 5 [numCols] => 3 [cells] => Array ( [1] => Array ( [1] => 网站名称 [2] => 网址 [3] => 类型 ) [2] => Array ( [1] => 百度 [2] => http://www.baidu.com [3] => 搜索引擎 ) [3] => Array ( [1] => 谷歌 [2] => http://www.google.com.hk [3] => 搜索引擎 ) [4] => Array ( [1] => 400电话 [2] => http://www.my400800.cn [3] => 企业网站 ) [5] => Array ( [1] => 新浪 [2] => http://www.sina.com.cn [3] => 门户网站 ) ) ) [1] => Array ( [maxrow] => 0 [maxcol] => 0 [numRows] => 0 [numCols] => 0 ) [2] => Array ( [maxrow] => 0 [maxcol] => 0 [numRows] => 0 [numCols] => 0 ))
? boundsheets?数组包含了对象的其它信息,数组按?workbook?索引。?第二个索引为名称:?$xl_reader->boundsheets[i]['name']?返回第?i?个表的表名 例如:?$sheetname = $xl_reader->boundsheets[0]['name']; // name of the first sheet ? $xl_reader-> boundsheets?数组示例:
Array( [0] => Array ( [name] => Sheet1 [offset] => 2148 ) [1] => Array ( [name] => Sheet2 [offset] => 3484 ) [2] => Array ( [name] => Sheet3 [offset] => 3760 ))
? PHP-ExcelReader?只能支持?BIFF7 ,BIFF8?格式的文件。包括?Excel95?到?Excel2003.?但是不包含?Excel5.0?及之前的版本?.?实际上?Excel XP?和?Excel 2003?使用的?BIFF8X?是?BIFF8?格式的一个扩展?.?所有添加的特性可能不被?PHP-ExcelReader.?锁支持。否则它只能以?Excel XP/2003?文件运行。

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

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),
