<?php class Excel { static $instance=null; private $excel=null; private $workbook=null; private $workbookadd=null; private $worksheet=null; private $worksheetadd=null; private $sheetnum=1; private $cells=array(); private $fields=array(); private $maxrows; private $maxcols; private $filename; //构造函数 private function Excel() { $this->excel = new COM("Excel.Application") or die("Did Not Connect"); } //类入口 public static function getInstance() { if(null == self::$instance) { self::$instance = new Excel(); } return self::$instance; } //设置文件地址 public function setFile($filename) { return $this->filename=$filename; } //打开文件 public function Open() { $this->workbook=$this->excel->WorkBooks->Open($this->filename); } //设置Sheet public function setSheet($num=1) { if($num>0) { $this->sheetnum=$num; $this->worksheet=$this->excel->WorkSheets[$this->sheetnum]; $this->maxcols=$this->maxCols(); $this->maxrows=$this->maxRows(); $this->getCells(); } } //取得表所有值并写进数组 private function getCells() { for($i=1;$i<$this->maxcols;$i++) { for($j=2;$j<$this->maxrows;$j++) { $this->cells[$this->worksheet->Cells(1,$i)->value][]=(string)$this->worksheet->Cells($j,$i)->value; } } return $this->cells; } //返回表格内容数组 public function getAllData() { return $this->cells; } //返回制定单元格内容 public function Cell($row,$col) { return $this->worksheet->Cells($row,$col)->Value; } //取得表格字段名数组 public function getFields() { for($i=1;$i<$this->maxcols;$i++) { $this->fields[]=$this->worksheet->Cells(1,$i)->value; } return $this->fields; } //修改制定单元格内容 public function editCell($row,$col,$value) { if($this->workbook==null || $this->worksheet==null) { echo "Error:Did Not Connect!"; }else{ $this->worksheet->Cells($row,$col)->Value=$value; $this->workbook->Save(); } } //修改一行数据 public function editOneRow($row,$arr) { if($this->workbook==null || $this->worksheet==null || $row>=2) { echo "Error:Did Not Connect!"; }else{ if(count($arr)==$this->maxcols-1) { $i=1; foreach($arr as $val) { $this->worksheet->Cells($row,$i)->Value=$val; $i++; } $this->workbook->Save(); } } } //取得总列数 private function maxCols() { $i=1; while(true) { if(0==$this->worksheet->Cells(1,$i)) { return $i; break; } $i++; } } //取得总行数 private function maxRows() { $i=1; while(true) { if(0==$this->worksheet->Cells($i,1)) { return $i; break; } $i++; } } //读取制定行数据 public function getOneRow($row=2) { if($row>=2) { for($i=1;$i<$this->maxcols;$i++) { $arr[]=$this->worksheet->Cells($row,$i)->Value; } return $arr; } } //关闭对象 public function Close() { $this->excel->WorkBooks->Close(); $this->excel=null; $this->workbook=null; $this->worksheet=null; self::$instance=null; } }; /* $excel = new COM("Excel.Application"); $workbook = $excel->WorkBooks->Open('D://Apache2//htdocs//wwwroot//MyExcel.xls'); $worksheet = $excel->WorkSheets(1); echo $worksheet->Cells(2,6)->Value; $excel->WorkBooks->Close(); */ $excel=Excel::getInstance(); $excel->setFile("D://kaka.xls"); $excel->Open(); $excel->setSheet(); for($i=1;$i<16;$i++ ) { $arr[]=$i; } //$excel->editOneRow(2,$arr); //print_r($excel->getAllData()); $str=$excel->getAllData(); include_once('mail.class.php'); $smtpserver="smtp.yeah.net"; $smtpserverport=25; $smtpuseremail="yanqihu58@yeah.net"; $smtpemailto="yanqihu@139.com"; $smtpuser="yanqihu58"; $smtppwd="123456789"; $mailtype="HTML"; $smtp=new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppwd); $message="你好"; //$message.="首页连接地址为:".$this->link_url."<br>"; //$message.="电子邮箱为:".$this->link_email."<br>"; //$message.="商务联系QQ:".$this->link_qq."<br>"; //$message.="商务电话QQ:".$this->link_tel."<br>"; //$message.="联系人:".$this->link_people."<br>"; $smtp->debug=false; foreach($str['email'] as $key=>$value){ $smtpemailto=$value; @$smtp->sendmail($smtpemailto,$smtpuseremail,$mailsubject,$message,$mailtype); exit; } //exit; $excel->Close(); ?>

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

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),
