PHP self if/else statement

dale282

Hi guys, I wonder if anyone could help me with something?

I'm trying to write an if/else statement to echo one thing if a file is in a particular drectory, or to do somthing else if not.

does anyone know if there's a wildcard character to add to if/else conditions? For example, if you wanted to search your computer for all html files you'd search for ".html" or "folder_name/*" to find all files in a folder - can this be done in php?

here's the sort of thing i'm looking for - replacing the *s with whatever the wildcard might be...

<?

$self = $_SERVER[’PHP_SELF’] ;

if ($self == "*/folderA/*") {

echo "You are in folder A!" ;

} else {

echo "You are not in folder A!" ;

}

?>

Thanks for your help.

why not do something like this:

<?php
if(dirname($_SERVER['PHP_SELF'])  == 'directory1') {
     echo 'you are in directory 1';
}
else {
     echo 'the directory you are in is: ' . dirname($_SERVER['PHP_SELF']);
}
?>

Thanks very much for that Rodney, that almost does what I'd like it to, but if the file is in a subfolder, it doesn't work...

i had a fiddle around and got this to do what i want, though there may be a more efficient way to write it?

<?

$self = $_SERVER['PHP_SELF'] ;

// str_replace to determine if filepath includes the directory 'phptest'
$phrase = $self ;
$find_what = "phptest" ;
$replace_with = phptest ;

$self1 = str_replace($find_what, $replace_with, $phrase);

// if phptest in current filepath, echo to say that, display filepath if not.

  if ($self1 == true) {
     echo "you are in directory 'phptest'";
  } else { 
     echo "the directory you are in is: $self" ;
  } 

?>

To be honest, I am not 100% sure as to what exactly it is you are after, so I came up with a simple "test" that seems to work.

Is this what you are after?

<?php
// current file:
$file = str_replace(array(dirname($_SERVER['PHP_SELF']), '/'), '', $_SERVER['PHP_SELF']);
echo 'File: ' . $file . '<br />';

// current directory info:
$directories = dirname($_SERVER['PHP_SELF']);
$directories = explode('/', $directories);
foreach($directories as $dir)
{
	if(!empty($dir))
	{
		$directory[] = $dir;
	}
}
echo 'Directory: ' . $directory[count($directory) - 1] . '<br />';
echo 'It is ' . (count($directory) - 1) . ' levels below the root';
?>

errrm, not quite no.

I was looking for an if/else statement to tell a user if the file is in a directory, or any subfolders contained within that directory. If, for example, the directory we were testing for was called 'phptest', I wanted something that told the user that they were in directory phptest if they were at www.domain.com/phptest/file.php and also www.domain.com/phptest/subfolder/file.php

the one i added using str_replace seems to do the trick, though there may be easier ways to do it.

hope that clears it up. thanks for your help!
