PHP Filesystem Reference Manual
file_get_contents() can read a file into a string. This function is the preferred method for reading the content of a file into a string. If the operating system supports it, memory-mapped technology will also be used to enhance performance.
string file_get_contents ( string $filename [, bool $use_include_path = FALSE [, resource $context [, int $offset = 0 [, int $maxlen ]]]] )
This function is similar to the file() function, but the file_get_content() function returns the file as a string, starting from the specified offset and up to maxlen bytes.
| Parameter | Description |
|---|---|
| filename | Required. Specifies the file to be read. |
| use_include_path | Optional. If you also want to search for files in use_include_path (in php.ini), set this parameter to '1‘. |
| context | Optional. Specifies the environment of the file handle. The context is a set of options that can modify the behavior of the stream. If NULL is used, it is ignored. |
| offset | Optional. Specifies the position in the file from which to start reading. This parameter is PHP 5.1 added. |
| maxlen | Optional. Specifies the number of bytes to read. This parameter is PHP 5.1 added. |
