Thanks for your reply

But still is not working my code is below

$tagName = "{INDIAN_TEST}" ;

$string = "You are {INDIAN_TEST} to vote if:

You are an Indian citizen. {INDIAN_TEST} 2. You are 18 years or older as on 1st January of the year when the electoral rolls are getting prepared. Currently, this will be 1st January, 2008 Ashvin {INDIAN_TEST} ";

if(preg_match("/\b".preg_quote($tagName, '/')."\b/i", $string))
{
echo "<br>IF";exit;
// return true;
}
else
{
echo "<br>ELSE";exit;
// return false;
}

But it going on else part

So any other thing required????

Your pattern won't match because there is no word boundary ("\b") between the space of "are " and the brace of "{INDIAN". Word boundaries are only when the character on side is a letter and the one on the other side is not.

You don't need word boundaries anyway, because you know where the boundaries of the pattern are: they're the braces.

And you don't need preg_replace, either. str_ireplace() would do the job without regular expressions.
