preg_match if tabulator at end of string

Question

How to check if there is a tab at the end of a string? Which pattern works? I tried /\+t$/ but i get "There is NO tab at the end of the string" even though there is a tabulator at the end.

<?php
$text = "Come to the dark side. We have cookies    ";
$pattern = "/\+t$/";

if(preg_match($pattern , $text)) 
{
   echo "There is a tab at the end of the string";
} 
else 
{
   echo "There is NO tab at the end of the string";
}
?>

Answer 1

Your regex /\+t$/ matches a + sign followed by character t at the end of a string.

I guess you want :

• /\t$/ : a tabulation at the end of the string
• or /\t+$/ : one or more tabulations at the end
