Do you have a URL we could look at? I (or another user) might be able to help.

I am trying to make the html input page take an amount that has commas and remove them and still spit out the correct amount. it only works if I leave out the commas. this is my code and I added your code to mine and I dont see a change in the results.

How would I go about checking the last 4 characters of a string? For example, if I wanted to change this string “hello!!!!” to be “hello”, only when there are 4 exclamations.

$outgoing = substr_replace($incoming,”",-1);

Zaur:

The trim() function removes leading and trailing whitespaces of a string.

Zaur,
You can check the last character in the string, as in the code below:

$st = “abcde “;
$len = strlen($st);
st[$len-1] == ‘ ‘ ? return false : return true;

Hi nice example, but I’m looking for the best way to find whether the sting include space at the end, if yes then return to false, no need to delete. Is there any way except regular expression?

You can also avoid the problem entirely by using implode(), so you don’t have the superfluous delimiters in the first place. :-)

You can also use rtrim().

The second, optional parameter of rtrim() is a character list. To use your example:

$string = “ASP, ASP Programming, CSS, Information Technology, JavaScript Programming, “;

$newstring=rtrim($string,’, ‘);

Printing or echo-ing $newstring would give you the same result.
