PHPExcel行数问题

Question

I have the next php code:

$arraylicitaciones=json_decode($_POST['ids']);
$x=0;
$arraydatos=array();
while($x<count($arraylicitaciones))
{
    $id=$arraylicitaciones[$x];
    $tipo=$arraylicitaciones[$x+1];

The query array generated after executing the query returns more than 5000 rows.I want to know,if someone can help,why if i only write 1640 rows with 23 columns each row,the phpexcel generates the .xls file but if I write 1650 rows with 23 columns too the server gives me an error 500(Internal Server Error)

Answer 1

1.) Edit: true.. seems not to be the case with the PHP implementation .. stay with xls

2.) PHPExcel is inefficient when it comes to memory usage. The standard PHP limit is only 100mb of memory - either try increasing the memory and see if it's good enough for you, or move on to other libraries.

consider https://github.com/mk-j/PHP_XLSXWriter for lower memory usage It's incredibly fast and uses little memory - but has no styling support.

Another option is https://github.com/SystemDevil/PHP_XLSXWriter_plus I've never used it but in theory it can support stying and is a fork of the other project, I would give it a go
