$img_base64_encoded = $row_sign_check['landlord_sign'];
$imageContent = file_get_contents($img_base64_encoded);
$path = tempnam(sys_get_temp_dir(), 'prefix');
file_put_contents ($path, $imageContent);
$landlord_sign = '<img src="'.$path.'">';


// $tenant_sign = $pdf->Image('@'.$images);

// Set some content to print
$html = <<<EOD
$landlord_sign
EOD;

想請問為甚麼我這段再local端測試都沒問題，圖片會照常顯示，但是放到server端上卻不會顯示，也沒有抱錯，謝謝
