Text to Check:


PHP Source:

<?php
// 2002-10-10 by Chris Snyder 
// this script uses aspell, but not the internal php spelling functions which are somewhat crippled by only being able to check words, not whole documents (as of ~php 4.2.2)
// requires that aspell be installed and working at /usr/local/bin/aspell -- see http://aspell.sourceforge.net/

// 2003-01-19 -- updated tempfile to use PHP's tempfile creation mech., also bumped year
// 2003-01-24 -- fixed bug that caused improper handling of words with no suggested corrections (thanks, Dekeyzer Stephane!)
// 2003-05-06 -- fixed a bug causing bad things to happen when multiple instances of incorrect words were found on any given line  (thanks, Dallas Brown!)
//             -- also fixed script so that $opener and $closer work for custom labeling of errors (thanks again, Dallas Brown!)
