Hi,

Have you looked at is_string() here

A string... as opposed to what? A number?

You may want to try ctype_alpha().

Is my code correct to check if the user input from actionscript is a alphapert? and return a error message to actionscript
[PHP]
$postalno=subst r($_GET["postal"],0,2);
if(ctype_alpha( $postalno)){

$report.="error "."="."Erro r text enter number"."&";
echo $report;


[/PHP]

[PHP]if(ctype_alpha( $postalno)){

$report.="error "."="."Erro r text enter number"."&";[/PHP]

Did you read the documentation for ctype_alpha() at all...?
