Download file php using relative path

And yes, relative urls just shouldn't be used at all. All local urls should be written as absolute paths, i. Great introduction, but doesn't help with the confusions introduced by require or include. I don't think I will ever completely understand what happens in a chain of include files to the current directory and whether the current directory is used by include directives when they interpret their path argument.

And that's before we consider the effects of the Include Path! Hey, I want to access a file located in a different folder. The file is called config. When i require it in another file called tables. Just read the article above, it explains what to do.

Thank you for helping me to make the site better! Hi, We have an application hosted in IIS. This application has file upload control. When i chose a file to upload from a folder it takes the full path along with file name and this full path is considered as file name in the system. Some times it exceedes max file name length and throws an error.

Please Help. But I don't have much experience with IIS. Good article. Very helpful article. It was previously mentioned that zip and exe files download automatically, without using PHP script.

First, create an HTML file with the following code. Here, the four anchor elements are defined to download the four types of files. Output The following dialog box will appear to download the file after clicking the zip file link. The user can then download the file or open the file in the archive manager. If you click on the image file, the image will be opened automatically in the browser, as shown in the following output.

You must save the file to make a copy of the image file in the local drive. In the same way, when you click on PDF and TEXT file links, the content of the file will be opened in the browser without downloading the file. The solution to this problem is to download the file forcibly using the built-in PHP readfile function. The readfile function is used in PHP script to forcibly download any file of the current location, or the file with the file path. The regular expression in the above example line no-8 will simply not allow those files whose name starts or ends with a dot character.

Note : Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB. Example 1 realpath example. On windows realpath will change unix style paths to windows style.
