你可以尝试
$gd = @imagecreatefromstring(file_get_contents($file_path));
if ($gd === false) {
throw new Exception ('Image is corrupted');
}
它应该适用于gd已知的大多数图像格式。此外,如果您需要特定的错误消息,可以使用error_get_last()。
It should work with most image formats known to gd. Also if you need specific error message you can use error_get_last().
@将禁止错误消息,imagecreatefromstring尝试打开已知的图像格式。如果失败,$ gd将具有值'false'并且不会抛出任何错误消息。
@ will suppress error messages, and imagecreatefromstring tries to open known image formats. If this fails, $gd will have value 'false' and no error messages are thrown.
编辑:
请注意,在这个例子中,@ operator也会从file_get_contents函数中获取任何错误。
Please not that in this example @ operator also will suprpess any errors from file_get_contents function.
