消耗内存的TCPDF并没有释放内存

Question

I am using TCPDF library to generate report on one of my application. When ever i generate PDF using TCPDF, chunk of memory get allocated like 256MB & after generating the PDF, that allocated memory is not getting free.

This is blocking around 2GB memory. So the final solution which i have is change the TCPDF lib with other lib.

Can anybody knows why TCPDF allocates the memory or is there any way to flush the memory after the pdf generation?

Answer 1

If you have PHP5 running on your server: does your TCPDF object have a __deconstruct() method?

If you have PHP4 running on your server: try unset($pdfobject) .

Run these methods once you're done creating/writing/printing your PDF.

Answer 2

Are you cleaning your output buffer in your View? I am also using TCPDF in some of my Cake projects, but never had this problem. Your view should have somthing like this:

<?php
// Start output buffering
ob_start();

// Your TCPDF code here

// Clean the output buffer
ob_end_clean();

Works just fine for me, memory is freed right after generation.
