async_read

NAME

async_read() - read a file into a string then executes a callback

SYNOPSIS

void async_read( string file, function callback );

DESCRIPTION

Read  a  line  of text from a file into a string.  Normally, read_file
takes a second and third arguments for start_line and number_of_lines to
read, but async_read will return the entire file to the callback.

The callback should follow this format:

    function(mixed res) {
        // -1 for file not read
        // string file contents otherwise
    }
