Backend DevelopmentPHP TutorialThinkphp5+PHPExcel realizes the function of batch uploading table data
This article mainly introduces the function of batch uploading table data in Thinkphp5 PHPExcel. Friends who need it can refer to it
1. First, download PHPExcel and put it in the vendor folder. My path is: project/ vendor/PHPExcel/, put the downloaded PHPExcel file here
2. Front-end code
<!DOCTYPE html>
<html>
<head>
<title>批量导入数据</title>
</head>
<body>
<form action="{:url('/index/index/importExcel')}" method="post" enctype="multipart/form-data">
<input type="file" name="myfile"><br/>
<input type="submit" value="批量的导入">
</form>
</body>
</html>
3.Backend code
/**
* 导入表格数据
* 先把文件上传到服务器，然后再读取数据存到数据库
*/
public function importExcel(){
header("content-type:text/html;charset=utf-8");
//上传excel文件
$file = request()->file('myfile');
//移到/public/uploads/excel/下
$info = $file->move(ROOT_PATH.'public'.DS.'uploads'.DS.'excel');
//上传文件成功
if ($info) {
//引入PHPExcel类
vendor('PHPExcel.PHPExcel.Reader.Excel5');
//获取上传后的文件名
$fileName = $info->getSaveName();
//文件路径
$filePath = 'public/uploads/excel/'.$fileName;
//实例化PHPExcel类
$PHPReader = new \PHPExcel_Reader_Excel5();
//读取excel文件
$objPHPExcel = $PHPReader->load($filePath);
//读取excel文件中的第一个工作表
$sheet = $objPHPExcel->getSheet(0);
$allRow = $sheet->getHighestRow(); //取得总行数
//$allColumn = $sheet->getHighestColumn(); //取得总列数
//从第二行开始插入，第一行是列名
for ($j=2; $j <= $allRow; $j++) {
$data['name'] = $objPHPExcel->getActiveSheet()->getCell("A".$j)->getValue();
$data['tel'] = $objPHPExcel->getActiveSheet()->getCell("B".$j)->getValue();
$data['addr'] = $objPHPExcel->getActiveSheet()->getCell("C".$j)->getValue();
$last_id = Db::table('users')->insertGetId($data);//保存数据，并返回主键id
if ($last_id) {
echo "第".$j."行导入成功，users表第:".$last_id."条！<br/>";
}else{
echo "第".$j."行导入失败！<br/>";
}
}
}else{
echo "上传文件失败！";
}
}
Output result:
Note:
Introducing a third-party class library using vendor(); is in the form of a namespace. The underlying code will automatically replace "." with "/", so when using "/", use "." instead;
The above code can be copied and used directly, but the database related information must be changed to your own !

php怎么把负数转为正整数Apr 19, 2022 pm 08:59 PMphp把负数转为正整数的方法：1、使用abs()函数将负数转为正数，使用intval()函数对正数取整，转为正整数，语法“intval(abs($number))”；2、利用“~”位运算符将负数取反加一，语法“~$number + 1”。
php怎么实现几秒后执行一个函数Apr 24, 2022 pm 01:12 PM实现方法：1、使用“sleep(延迟秒数)”语句，可延迟执行函数若干秒；2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句，可延迟执行函数若干秒和纳秒；3、使用“time_sleep_until(time()+7)”语句。
php怎么除以100保留两位小数Apr 22, 2022 pm 06:23 PMphp除以100保留两位小数的方法：1、利用“/”运算符进行除法运算，语法“数值 / 100”；2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值，并保留两位小数。
php怎么根据年月日判断是一年的第几天Apr 22, 2022 pm 05:02 PM判断方法：1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式；2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的，因此真实天数需要在此基础上加1。
php怎么判断有没有小数点Apr 20, 2022 pm 08:12 PMphp判断有没有小数点的方法：1、使用“strpos(数字字符串,'.')”语法，如果返回小数点在字符串中第一次出现的位置，则有小数点；2、使用“strrpos(数字字符串,'.')”语句，如果返回小数点在字符串中最后一次出现的位置，则有。
php怎么替换nbsp空格符Apr 24, 2022 pm 02:55 PM方法：1、用“str_replace(" ","其他字符",$str)”语句，可将nbsp符替换为其他字符；2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。
php字符串有没有下标Apr 24, 2022 am 11:49 AMphp字符串有下标。在PHP中，下标不仅可以应用于数组和对象，还可应用于字符串，利用字符串的下标和中括号“[]”可以访问指定索引位置的字符，并对该字符进行读写，语法“字符串名[下标值]”；字符串的下标值（索引值）只能是整数类型，起始值为0。
php怎么查找字符串是第几位Apr 22, 2022 pm 06:48 PM查找方法：1、用strpos()，语法“strpos("字符串值","查找子串")+1”；2、用stripos()，语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的，因此两个函数获取的位置需要进行加1处理。

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),
