I want to match a string using REGEX which follows the syntax:
Text/number
So my preg_match() function is...
if(preg_match("/[^A-Za-z/0-9]$/ ", $folio))
$err[] = "Wrong value, it's should be lik: C/455";
But getting error message...

Try this:
$folio = "Text/15";
if(preg_match('~[a-z]/[\d]~i', $folio))
echo "match";
else
echo "no match";

i think you need to escape the '/', i.e. replace with //

@MukeshSoni No, because I use
~ as prefix/suffixYou needed to escape / using \. Also numbers is a subset of text and you need to include it in your text part. You need one or more text/numeric characters, so a + is required.
It adds up to the following statement:
if(preg_match("/^[A-Za-z0-9]+\/[0-9]+$/", $folio))

You either need to escape / or use different char to surround regexp, for example:
if(preg_match("@[^A-Za-z/0-9]$@ ", $folio))
Comments
if ( ! preg_match('/\b[a-z]+\/[0-9]+\b/i', $folio)) {
$err[] = "Wrong value, it's should be like this: C/455";
}
