$_SERVERįilesystem- (not document root-) based path to the current script, after the server has done any virtual-to-real mapping. file.php, $_SERVER will contain the relative path specified by the user.

Note: If a script is executed with the CLI, as a relative path, such as file.php or. The absolute pathname of the currently executing script. The query string, if any, via which the page was accessed. If PHP is running as a command-line processor this variable contains the script name since PHP 4.3.0.

The _FILE_ constant contains the full path and filename of the current (i.e. For instance, $_SERVER in a script at the address would be /test.php/foo.bar. The filename of the currently executing script, relative to the document root. The definitions are taken from the PHP manual( Predefined Variables) and are modified slightly. The following is a list of the most commonly used methods to find the location of the current file. But the problem is to find one that is consistent across all servers. There are various methods of find the path of the current file in PHP.

No Problem! mkdir has you covered. Recursively make directories in PHP using mkdir by Gav Here is how you can fix node incompatibility error, using 'Node Sass does not yet support your current environment' as an example. Node Sass does not yet support your current environment by Gav In this post I'll show you how to change the aspect ratio of an image or element using CSS, and explain why this is important. This example takes the parent directory of ‘_FILE_’ and then resolves ‘/.’ using realpath() to move it 1 level higher.Ĭhange the aspect ratio of an image using CSS by Gav There are a few ways that we could achieve this, one of them is using dirname(). This means that we have to remove the ‘index.php’ from our ‘_FILE_’ string. If we are going back even further than PHP 5.3 then we would have to use realpath(), dirname() and the ‘Magic Constant’ ‘_FILE_’.Įssentially, realpath() won’t accept a file, only a path. If we were to use ‘/./.’ then we would move 2 levels higher, and so on. In this example, realpath() resolves the reference ‘/.’ in relation to ‘_DIR_’ and moves us 1 level higher.

The ‘Magic Constant’ ‘_DIR_’ was added to PHP in 5.3, so for people 5.3 to 5.6 we can move directory levels like this:Īgain, assuming that our script is running in /path/to/file/index.php: $dir = realpath(_DIR_. If you happen to be using an older version of PHP then luckily we can use realpath(). By specifying a level of 2 we now move to ‘/path/to’ instead. If we use ‘_FILE_’ it is slightly different: $dir = dirname(_FILE_, 2) īecause ‘_FILE_’ returns the file in the string, the parent directory is ‘/path/to/file’. Remember: dirname() returns the parent directory, so using ‘dirname(_DIR_)’ will return the parent directory of ‘_DIR_’. In this case ‘_DIR_’ is ‘/path/to/file’, so 2 levels higher is ‘/path’. Let’s assume that our script is running in /path/to/file/index.php: $dir = dirname(_DIR_, 2) īy using the ‘Magic Constant’ ‘_DIR_’ and specifying a level of 2, we are asking dirname() to return 2 levels up from the parent of ‘_DIR_’. To use this we first pass the file or directory path as a string, and then specify how many levels we would like to move up from that directory. In PHP 7 and above we can specify how many levels we would like to move. This function will return the parent directory of whatever path we pass to it. If you are using PHP 7.0 and above then the best way to navigate from your current directory or file path is to use dirname(). We will also be using ‘Magic Constants’ in this post, but handily I’ve explained these a bit here. I know of two relatively simple ways to do this one using dirname() I’ve recently been helping colleagues learn PHP, and I frequently get asked how to move up and down directory levels in relation to the current file.

I often find that simple things are the ones most forgotten or unknown.
