You're not using it in the proper context.
LEFT() is indeed a valid MySQL function, but you're calling it as a PHP
function, not a MySQL function. You have to use LEFT() in the query that
you use to select your data. For example:
$result = mysql_query ("SELECT LEFT(fulltext,512) FROM tbl_name");
while ($myrow = mysql_fetch_array ($result)
Alternatively, change your echo statement to call the PHP function
substr ($myrow["fulltext"], 0, 512). See the PHP manual.
