PHPExcel Allowed memory size of 内存泄漏解决办法_PHP教程

public function Destroy() {
foreach($this->_cellCollection as $index => $dummy) {
$this->_cellCollection[$index] = null;
}
}

并在 PHPExcel 类中增加方法：

public function Destroy() {
foreach($this->_workSheetCollection as $index => $dummy) {
$this->_workSheetCollection[$index]->Destroy();
$this->_workSheetCollection[$index] = null;
}
}

ini_set('memory_limit', '-1');

或

ini_set('memory_limit','265M')

memory_limit = 12M

php_value memory_limit 12M
