我将Laravel项目托管到000webhost，我的项目可以以pdf格式进行报告。我使用dompdf来做所有的pdf事情。在我的本地主机服务器（xampp）中，dompdf可以正常工作，没有错误，并且可以很好地呈现html。在实时服务器中，我收到错误500“糟糕，我们的服务器出了点问题。”。我找不到任何解决方案，我认为这是执行时间，我将其提高到2000秒仍然有500。
这是我的控制器
public function retur_preport(Request $request)
{
ini_set('max_execution_time', '2000');
ini_set('memory_limit','512M');
$tgl1 = date('Y-m-d', strtotime($request->input('tanggal_mulai')));
$tgl2 = date('Y-m-d', strtotime($request->input('sampai_tanggal')));
if($tgl1 > date('Y-m-d') || $tgl2 > date('Y-m-d')){
return redirect('upper/laporan/retur')->with('error','Tanggal yang diinput tidak bisa lebih besar dari '.date('d M Y').' (hari ini)');
}elseif($tgl2 != '1970-01-01' && $tgl1 > $tgl2){
return redirect('upper/laporan/retur')->with('error','Tanggal mulai tidak bisa lebih besar dari inputan tanggal sampai');
}elseif($tgl1 == '1970-01-01' && $tgl2 == '1970-01-01'){
return redirect('upper/laporan/retur')->with('error','Salah satu dari kedua tanggal harus diisi');
}elseif($tgl1 == '1970-01-01'){
$r = \App\Retur::whereDate('tgl_retur',$tgl2)->orderBy('tgl_retur','desc')->get();
$pdf = PDF::loadview('pimpinan/laporan/retur/report', compact('r','tgl1','tgl2'))->setPaper('a4','landscape');
return $pdf->download('laporan retur tanggal '.date('d-M-Y', strtotime($tgl2)).'.pdf');
}elseif($tgl2 == '1970-01-01'){
$r = \App\Retur::whereBetween('tgl_retur',[$tgl1, date('Y-m-d')])->orderBy('tgl_retur','desc')->get();
$pdf = PDF::loadview('pimpinan/laporan/retur/report',compact('r','tgl1','tgl2'))->setPaper('a4','landscape');
return $pdf->download('laporan retur tanggal '.date('d-M-Y', strtotime($tgl1)).' sampai tanggal '.date('d-M-Y').'.pdf');
}else{
$r = \App\Retur::whereBetween('tgl_retur',[$tgl1,$tgl2])->orderBy('tgl_retur','desc')->get();
$pdf = PDF::loadview('pimpinan/laporan/retur/report', compact('r','tgl1','tgl2'))->setPaper('a4','landscape');
return $pdf->download('laporan retur tanggal '.date('d-M-Y', strtotime($tgl1)).' sampai tanggal '.date('d-M-Y', strtotime($tgl2)).'.pdf');
}
}
