how to check if a ";" is at the end of a string?

[Stylewriter]

hi!
I have got a problem:
how can I check if a ";" is at the end of a string?

e.g.
$str = "This is a test;";

now I want the php script to check if at the end of $str is a ";" - if so, there should come an echo "found a ";" at the end"; !

perhaps you can help me, by saying how the function is called.

thanx a lot,

$str = "blah blah;";

if (substr($str, strlen($str) - 1, 1) == ";") {
    echo "found ;!";
}

Should work.

ok, thanx!
and how is it possible that the ";" at the end of the string will be deleted?
sry, but I don't know the names of the functions allready...

[The Hobo]

$str = "blah blah;";

if (substr($str, strlen($str) - 1, 1) == ";") {
    //if the ; exists, remove it:
    $str = substr($str, 0, strlen($str) - 1);
}

echo $str; //output: blah blah

Function substr():
Syntax: substr (string string, int start [, int length])
Description: Substr returns the portion of string specified by the start and length parameters.

Example:

echo substr("12345", 1, 2);
//output: 23

Function strlen():
Syntax: strlen (string str)
Description: Returns the length of string.

Example:

echo strlen("1234");
//output: 4

Hope this helps.
