使用 symfony 表单验证器进行批量插入
我收到用户发来的 CSV 文件,我想将其插入数据库。我想使用表单验证:
$pf = new ProductForm();
$old_memory_usage = 0;
while($data = $csvreader->read())
{
$mem = memory_get_usage() / 1024;
echo "Memory-Usage: " . $mem . " KB; Mem-Diff: " . $mem - $old_memory_usage . "\n";
$old_memory_usage = $mem;
$p = new Product();
$p->fromArray($data);
$pf->bind($p->toArray(), array());
if($pf->isValid())
{
$p->save();
}
else
{
//display error message to the user
}
}
当 isValid() 返回 true 时,效果很好。内存差异为 0 KB。但如果“表单”中存在错误,则内存差异为 6-7 KB。因此,当 CSV 文件非常大时,我会收到 allowed_memory 错误。
我尝试释放表格:
unset($pf)
$pf = null;
$pf = new ProductForm();
没有成功。情况更糟!
和想法? 谢谢!
i receive an CSV File from the User and I want to insert it into the Database. I want to use the Form Validation:
$pf = new ProductForm();
$old_memory_usage = 0;
while($data = $csvreader->read())
{
$mem = memory_get_usage() / 1024;
echo "Memory-Usage: " . $mem . " KB; Mem-Diff: " . $mem - $old_memory_usage . "\n";
$old_memory_usage = $mem;
$p = new Product();
$p->fromArray($data);
$pf->bind($p->toArray(), array());
if($pf->isValid())
{
$p->save();
}
else
{
//display error message to the user
}
}
This works fine when isValid() returns true. The Memory Difference is 0 KB. But if there is an Error in the "form" the memory-difference is 6-7 KB. So I get an allowed_memory error when the CSV-File is very huge.
I tryed to free the form like:
unset($pf)
$pf = null;
$pf = new ProductForm();
no success. It is just worse!
ans ideas?
thx!
