PHP strpos（）不工作，总是进入if条件

Question

I'm trying to check if a specific character is not present in a string in my code and apparently php doesn't care about anything and always gets inside the if

foreach($inserted as $letter)
{
    if(strpos($word, $letter) !== true) //if $letter not in $word
    {
        echo "$word , $letter, ";
        $lives--;
    }
}

In this case $word is "abc" and $letter is "b", I've tried changing a lot of random things like from true to false and things like that but I can't get it, can anyone help me please?

Changing the way you validate should fix it, like below:

     foreach($inserted as $letter)
        {
            //strpos returns false if the needle wasn't found
            if(strpos($word, $letter) === false) 
            {
                echo "$word , $letter, ";
                $lives--;
            }
        }
