how can I put a condition in if so that it doesn’t happen if the array has "..." at the end of the sentence

Question

how can I put a condition on if(if (strlen($string) > $size) {) so it doesn’t happen if the array has "..." at the end of the sentence

$prod->setNome(Utility::limitaString($prod->getNome(), 30));

    public static function limitaString ($string, $size = 50) {
    if (strlen($string) > $size) {
        $string = substr($string, 0, $size);
        for ($i=$size; $i>=0; $i--) {
            $limiters = array(" ", "\n", "\t");
            if (in_array($string[$i], $limiters)) {
                if ($string[$i-1] == "\r")
                $i = $i-1;
                $string = substr($string, 0, $i);
                $string .= "...";
                return $string;
            }
        }
        $string .= "...";
    }
    return $string;
}

This function above is done to reduce the sentence to 30 characters and add "..." at the end of the sentence. but I need this condition for some already abbreviated sentence that I don’t want by the method.

how would be condition for array with at the end "...".

Answer 1

Try this:

if (!stripos($string, "...") {
   //se ela achar as retiscencias ela não executa
   //seu codigo AQUI
}

What she’ll do is, look in her variable string if there is some part of the text "...", if not, it will execute your code. It searches throughout the $string ignoring the position, seeking only to find what was requested. I think this may solve your problem.

Link for the PHP function. Good luck!

I believe this should work:

$prod->setNome(Utility::limitaString($prod->getNome(), 30));

    public static function limitaString ($string, $size = 50) {
    if (strlen($string) > $size) {
        $string = substr($string, 0, $size);
        for ($i=$size; $i>=0; $i--) {
            $limiters = array(" ", "\n", "\t");
            if (in_array($string[$i], $limiters)) {
                if ($string[$i-1] == "\r")
                $i = $i-1;
                $string = substr($string, 0, $i);
                if( strstr($string,"...")){
                    //return null
                }else{
                    $string .= "...";
                }
                return $string;
            }
        }
        if( strstr($string,"...")){
             //return null
        }else{
             $string .= "...";
        }
    }
    return $string;
}

Note: I did not test.

Answer 3

I did not understand very well this array, but I will do what I understood:

preg_match(".{3}$", $string, $ultimos3);
if ($ultimos3[0] != "..." && strlen($string) > $size)

See working on Ideone.

What I did:

On the first line, I used a regular expression(regex) to get the last 3 characters.

On Monday, it’s the same if which you were using, but now it checks whether the regex has returned ....

References:

• Function preg_match in official php documentation.

Answer 4

You can use the function replace PHP, for this just inform a negative number.

Checks the size of the variable string and checks whether the last three characters of the variable string are not the three points.

if (strlen($string) > $size && substr($string,-3) !== '...')

One observation to make, is that in the example above, will check whether the variable size string is greater than the value reported in the variable $size, if it is the condition will do the check if the variable string does not contain the three points at the end, returning true ( that does not contain the three points ) it will limit the variable string, if contain it will not limit.
