PHP function to count files in a directory on the server
Simple PHP function to count files in a directory on the server, how to count files in a directory with php.

 



For this we use $_SERVER['DOCUMENT_ROOT'], glob() and count()

Description
array glob ( string $pattern [, int $flags ] )

The glob() function searches for all the pathnames matching pattern according to the rules used by the libc glob() function, which is similar to the rules used by common shells.

 

Description
int count ( mixed $var [, int $mode ] )

Returns the number of elements in var , which is typically an array, since anything else will have one element.

For objects, if you have SPL installed, you can hook into count() by implementing interface Countable. The interface has exactly one method, count(), which returns the return value for the count() function.

If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is NULL, 0 will be returned.

PHP function to count files in a directory:

function count_files ($dir) {
$count = count(glob($_SERVER['DOCUMENT_ROOT'].$dir . "*")) ;
return $count;

}

Depending on which file names you need to count, replace "*" with what ever suits your needs.

Go to Glob function on php.net website to see what other modifications you can do to it.

you're missing a parenthesis
this -> $count = count(glob($_SERVER['DOCUMENT_ROOT'].$dir . "*") ;
should be ->$count = count(glob($_SERVER['DOCUMENT_ROOT'].$dir . "*") );
