Bagaimana untuk mengimport jadual Excel dengan gambar dalam PHP? Bagaimana untuk mengeksport gambar ke Excel? Bagaimana untuk menentukan gaya untuk Excel yang dieksport untuk menjadikannya lebih cantik? Artikel berikut akan membantu anda menyelesaikannya satu persatu. Saya harap ia akan membantu anda!
Excel ialah alat yang biasa digunakan untuk pengumpulan data dan statistik Biasanya dalam sesetengah platform maklumat, untuk mencapai tanpa kertas atau pergi ke awan, memang begitu diperlukan untuk Memindahkan data daripada komputer pejabat ke platform, atau memuat turun data pada platform untuk digunakan oleh bukan pembangun, sudah pasti akan melibatkan import dan eksport data, dan format data mestilah Excel.
Artikel ini akan menggabungkan keperluan pembangunan sebenar dan meringkaskan import dan eksport Excel semasa proses pembangunan yang terlibat:
Dari segi penempatan, untuk data dengan banyak gambar dalam Excel, adalah perlu untuk memanjangkan masa tamat atau masa berjalan dan tambahkan had saiz muat naikRepositori kod: https://github.com/QuintionTang/crayon-thinkphp

nginx + php-fpm，对于Excel中图片比较多的数据导入需要设置加大上传文件的限制和超时时间。413 request Entity too Large 错误，解决的办法是在 nginx 配置中增加以下配置：client_max_body_size 2048m;
php.ini ：upload_max_filesize = 2048M
post_max_size = 2048M
nginx 配置：fastcgi_connect_timeout 600;
php-fpm 中的 www.confrequest_terminate_timeout = 1800
docker 镜像，这样可以确保环境迁移或者其他场合需要，可以快速完成环境配置，而且不容易出问题。
