php simpleImage类捕获异常错误

加载图像时SimpleImage类未捕获异常代码如下：

public function load($filename) {
        //echo $filename; exit;
    $image_info = getimagesize($filename);
    $this->image_type = $image_info[2];

    if ($this->image_type == IMAGETYPE_JPEG) {
        $this->image = imagecreatefromjpeg($filename);
    } elseif ($this->image_type == IMAGETYPE_GIF) {
        $this->image = imagecreatefromgif($filename);
    } elseif ($this->image_type == IMAGETYPE_PNG) {
        $this->image = imagecreatefrompng($filename);
    }
}

您没有捕获异常，如果异常不满足条件，则最后一次捕获异常。这是更新后的代码

public function load($filename) {
        //echo $filename; exit;
    $image_info = getimagesize($filename);
    $this->image_type = $image_info[2];

    if ($this->image_type == IMAGETYPE_JPEG) {
        $this->image = imagecreatefromjpeg($filename);
    } elseif ($this->image_type == IMAGETYPE_GIF) {
        $this->image = imagecreatefromgif($filename);
    } elseif ($this->image_type == IMAGETYPE_PNG) {
        $this->image = imagecreatefrompng($filename);
    } else {
        throw new Exception("The file you're trying to open is not supported");
    }
}

我认为这会解决问题。

检查

$image\u info

是否为数组。否则，如果文件名不是图像文件或无法作为图像读取，则可能会产生错误。
