PHPExcel throws Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 71 bytes)

Question

I am using PHPExcel (found here: https://github.com/PHPOffice/PHPExcel). If i try to read more than approximately 2000 rows then it shows memory error as follows.

Answer 1

Consider using cell caching to reduce the memory required to hold the workbook in memory, as described in section 4.2.1 of the developer documentation

And consider not using toArray() and then using that to build another array in memory.... doing this is really using a lot of memory to hold duplicated data, when you could simply loop through the rows and columns of the worksheet to do what you need
