允许在PHP变量和文件扩展名的<img标记中区分大小写

Question

I built a PHP script that dynamically generates & displays an IMG tag like this:

<img src=/img/{$row['Invl_InventoryNumber']}.BMP>

This worked great on a Windows server where case-sensitivity was not an issue.

We moved the script to Linux and have found that the files have both .BMP and .bmp file extensions AND ALSO the $row['Invl_InventoryNumber] variable contains Alphabetical values that are uppercase too.

Example: RZP.bmp OR rzp.bmp OR RZP.BMP OR RzP.bmp OR Rzp.BMP etc, etc.

I have no control over the naming scheme of the files, they are created by a human but need to account/look for matching files names. I was thinking of some sort of CASE or if/elseif statement but was not sure if there is a better way to trigger the value to check all possibilities.

Answer 1

This is a limitation of the some Unix OS;

So I suggest that you standardize your files or save the same name (with cappitalized when there are) in your database.

However, you can try to use "mod_speling" if you to serve your pages with Apache.
