mb_stripos

    (PHP 5 >= 5.2.0, PHP 7, PHP 8)

    mb_stripos — Finds position of first occurrence of a string within another, case insensitive

    Опис

    function mb_stripos(
        string $haystack,
        string $needle,
        int $offset = 0,
        ?string $encoding = null
    ): int|false

    mb_stripos() returns the numeric position of the first occurrence of needle in the haystack string. Unlike mb_strpos(), mb_stripos() is case-insensitive. If needle is not found, it returns false.

    How works on examples mb_stripos:

First we will watch example on symbols(..?).
<?php
$text = "Look! It's a text! Wow!"; //simple text
$spaceIsHere = mb_stripos($text," "); //you can replace " " on something what you need or want
$text2 = mb_substr($text,$spaceIsHere); //cutting text with $spaceIsHere
print ($text2); 
/* Print will show that result:
" It's a text! Wow!"
Look. That " " wasn't cutted, because mb_substr don't write in var position after " " - he write WHERE is " " in string. */
?>

Also it can work on words, sentences...
Here's one of examples:
<?php
$text = "Look! It's a text! Wow!"; //familiar text, right?)
$afterNeededWord = mb_stripos($text,"text!"); //you can replace "text!" on something else what you need
$text3 = mb_substr($text, $afterNeededWord); //cutting string (it is string? im stupid in that question xD)
print ($text3); 
/* Print will show that result:
"text! Wow!"
Explaining the same. */
?>

I hope it was useful with my "good" English skills. ;D
Have a nice day, coder.
