how to check if '.'[dot] is present in string or not ? strstr is not working in php

Question

I am trying to see if . [dot] is present in string or not.

I have tried strstr but it returns false.

here is my code :-

<?php
$str = strpos("true.story.bro", '.');
if($str === true)
{
        echo "OK";
} else {
        echo "No";
}
?>

I want to see if '.' is present in string or not, I can do with explode, but i want to do in 1 line, how could i do that ?

Thanks

Solution

You may use strpos directly.

if (strpos($mystring, ".") !== false) {
    //...
}

Hope this help :)

You're welcome! In fact, strpos is a "confused?" int that return false if the needle part is not present in the sentence. Just pay attention to the operator !== that validate the type of strpos, as != could also make this true if strpos return an int that can be equivalent to FALSE, which would be an error.
