TCPDF 内存问题允许 134217728 字节的内存大小耗尽
TCPDF Memory Issue Allowed memory size of 134217728 bytes exhausted
我正在使用 TCPDF 下载 PDF。对于较小的记录，它正在为大数据工作 fine.But，即 1000 条记录，它显示以下错误，
Fatal error: Maximum execution time of 30 seconds exceeded
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes)
我已经使用 ini_set 在 php 中设置了内存限制和最大执行时间，但它不是 works.I 还尝试在 [=22= 中更改 memory_limit 的值] 从 128M 到 512M.This 也不起作用。

请任何人帮助我解决这个问题。
在您的代码中添加这一行
set_time_limit(0);
还有这个
ini_set('memory_limit', '-1');// 这不是正确的解决方案，但它可以解决问题。
或者
ini_set('memory_limit', '640M'); //在你的 php 文件中设置适当的内存限制
我正在使用 TCPDF 下载 PDF。对于较小的记录，它正在为大数据工作 fine.But，即 1000 条记录，它显示以下错误，
