(PHP 4 >= 4.0.6)
fbsql_error -- Returns the text of the error message from previous FrontBase operationReturns the error text from the last fbsql function, or '' (the empty string) if no error occurred.
Errors coming back from the fbsql database backend dont issue warnings. Instead, use fbsql_error() to retrieve the error text. Note that this function only returns the error text from the most recently executed fbsql function (not including fbsql_error() and fbsql_errno()), so if you want to use it, make sure you check the value before calling another fbsql function.
<?php
fbsql_connect("marliesle");
echo fbsql_errno().": ".fbsql_error()."<BR>";
fbsql_select_db("nonexistentdb");
echo fbsql_errno().": ".fbsql_error()."<BR>";
$conn = fbsql_query("SELECT * FROM nonexistenttable;");
echo fbsql_errno().": ".fbsql_error()."<BR>";
?>
