PHP export mysql database to excel table_PHP tutorial
There are many ways to use php to export mysql database into excel tables. The simplest one is to directly use the php fputcsv function. You can also directly enter the csv format. To generate the excel standard format, we need to use a third-party plug-in
Method 1, use fputcsv
The code is as follows | Copy code | ||||||||
// Output the Excel file header, you can replace user.csv with the file name you want header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="user.csv"'); header('Cache-Control: max-age=0'); // Get data from the database. In order to save memory, do not read the data into the memory at once. Just read it line by line from the handle $sql = 'select * from tbl where ……'; $stmt = $db->query($sql);
$fp = fopen('php://output', 'a'); //Output Excel column name information $head = array('Name', 'Gender', 'Age', 'Email', 'Telephone', '……'); foreach ($head as $i => $v) { // Excel for CSV supports GBK encoding, it must be converted, otherwise the code will be garbled $head[$i] = iconv('utf-8', 'gbk', $v); } //Write data to the file handle through fputcsv fputcsv($fp, $head); // Counter $cnt = 0; // Every $limit line, refresh the output buffer, not too big, not too small $limit = 100000; // Fetch data line by line without wasting memory while ($row = $stmt->fetch(Zend_Db::FETCH_NUM)) { $cnt ++; if ($limit == $cnt) { //Refresh the output buffer to prevent problems caused by too much data ob_flush(); flush(); $cnt = 0; } foreach ($row as $i => $v) { $row[$i] = iconv('utf-8', 'gbk', $v); } fputcsv($fp, $row); } |
The code is as follows | Copy code |
/*Connect to database*/ $DB_Server = "localhost"; $DB_Username = "root"; $DB_Password = "123456"; $DB_DBName = "mydb"; //Target database name $DB_TBLName = "mytable"; //Target table name $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect."); mysql_query("Set Names 'utf8'");<🎜> <🎜>$savename = date("YmjHis"); //Export excel file name $file_type = "vnd.ms-excel"; $file_ending = "xls"; header("Content-Type: application/$file_type;charset=utf8"); header("Content-Disposition: attachment; filename=".$savename.".$file_ending"); //header("Pragma: no-cache");<🎜> <🎜>/*Write remark information*/ $now_date = date("Y-m-j H:i:s"); $title = "Database name: $DB_DBName, data table: $DB_TBLName, backup date: $now_date"; echo("$titlen");<🎜> <🎜>/*Query database*/ $sql = "Select * from $DB_TBLName"; $ALT_Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database"); $result = @mysql_query($sql,$Connect) or die(mysql_error());<🎜> <🎜>/*Write table field name*/ for ($i = 0; $i < mysql_num_fields($result); $i++) { echo mysql_field_name($result,$i) . ","; } echo "n";<🎜> <🎜>/*Write table data*/ $sep = ",t"; while($row = mysql_fetch_row($result)) { $data = ""; for($i=0; $i $data .= "NULL".$sep; //Processing NULL fields elseif ($row[$i] != "") $data .= "$row[$i]".$sep; else $data .= "".$sep; //Processing empty fields } echo $data."n"; } ?> |
Example 3, the second one is almost done
The code is as follows | Copy code | ||||||||||||||||||||||||||||||
if($temp_list){//有数据 $Html.='
$Html.=''; $mime_type = 'application/vnd.ms-excel'; header('Content-Type: ' . $mime_type); header('Content-Disposition: attachment; filename="invoice.xls"'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); echo $Html; |
Sometimes excel will automatically convert the format of numbers, so some mobile phone numbers, ID cards, etc. will be messed up, so you can define them first when exporting
The code is as follows

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4.
