Checking file types

[DeepBlerg]

Hi,

I have a form whereby the user can upload either a Word DOC or an Acrobat PDF.

I am doing a check based on the $_FILES[]['type'] value for either 'application/msword' or 'application/pdf'.

However I have noticed during my Googling that Word files are also referred to as 'application/x-msword-doc', 'application/vnd.ms-word' and so forth.

Will I have to check for all these different variants or is the $_FILES[]['type'] value specific to my server so no matter what browser someone uses I can always check for 'application/msword'?

You could use strstr() to find just "word". However, I suggest storing all variable types that you want to allow in an array, and then use in_array().

If (in_array($_FILES[...]['type'], $fileTypeArray)) {
    ...
}
