php - 无法在智能手机中获取文件的 tmp_name ($_FILES)

Question

这是我的 html 表单:

<form method="post" action="filename.php" enctype="multipart/form-data">
     <input id="file_upload" name="image[]" value="Upload" multiple="" type="file">
     <button type="submit">Submit</button>
</form>

当我在 filename.php 文件中打印 $_FILES 时，我可以在 PC 中获取以下数组:

Array
(
[name] => Array
    (
        [0] => Sket-printed-shirt.jpg
    )

[type] => Array
    (
        [0] => image/jpeg
    )

[tmp_name] => Array
    (
        [0] => /tmp/phpSA6YF5
    )

[error] => Array
    (
        [0] => 0
    )

[size] => Array
    (
        [0] => 280515
    )

)

但在智能手机中低于阵列，例如:摩托罗拉 G4 plus、G5 plus 和 HTC one mini 2

Array
(
[name] => Array
    (
        [0] => Sket-printed-shirt.jpg
    )

[type] => Array
    (
        [0] => image/jpeg
    )

[tmp_name] => Array
    (
        [0] => 
    )

[error] => Array
    (
        [0] => 1
    )

[size] => Array
    (
        [0] => 
    )

 )

您没有 tmp_name 的原因是上传失败，错误代码为 1，这表明文件太大。请参阅:upload file error codes .

UPLOAD_ERR_INI_SIZE Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.
