Question

I am trying to make a function that cuts the white spaces in a string and ads punctuation if there isn’t any.

This is my test string:

$test = 'Hey there I am traa la la           ';

I want it to turn into this:

$test = 'Hey there I am traa la la.';

Here is the function I have tried:

function test($mytrim){
        for($i = 0; $i <= 5; $i++){
            if(substr($mytrim, 0, -1) == ''){
                $mytrim = substr($mytrim, 0, -1);
            }
        }
        $punct = array(".",",","?","!");
        if(!in_array($mytrim, $punct)){ $mytrim .= '.'; } 
        return $mytrim;
    }

It returns this:

$mytrim = 'Hey there I am traa la la. .';

Any ideas why it is not working?

PHP has a built in trim function. as for the punctuations, your code should work fine (appending).

Code sample :

<?php

    $testString = "   hello world      ";
    $trimmedString = trim($testString); // will contain "hello world"
    $lastChar = substr($trimmedString, strlen($trimmedString)-1); // will be "d"
    $punct = array(".",",","?","!");
    if(!in_array($lastChar, $punct))
        echo $trimmedString.'.'; //will output "hello world."
