PHP: Find values in array with preg_grep without case sensitive

around this issue I have an array and I want to find values in it like in sql "LIKE". This works fine, but it is case sensitive. , You have to put the regex modifier after the delimiters like this:
code :
$result = preg_grep('~' . $string . '~i', $fileArray);
                                   //^^See here the Modifier
                                   //|Here the delimiter

it should still fix some issue Rather than having $uri in your string for preg_grep, concat it into a $pattern var first (for ease of reading mostly plus you can echo it and check as the above comment suggested):
code :
$uri = 'something';
$pattern = '/(.*)GET \/'.$uri.'(.*)/';
$array = preg_grep($pattern, $starting_array);
print_r($array);

Any of those help Is there a chance to search in the preg_grep input with non case sensitive search? , Just do
code :
$checkAuth = preg_grep("/CN=".$cn_name."/i", $entries[0]["member"]);

around this issue Keeping all tag and attribute names in lower-case will always work, but HTML5 is case-insensitive.

will help you You could split the word characters to an array and loop them, and split the characters from the specified string to an array.
If one of the word characters occur in the characters from the specified string array, remove the character from both arrays.
code :
$words = ["apple", "sample", "app", "justappgg", "тоҷик", "отабек", "баҳодурбек", "APELCIN", "API", "pap"];
mb_internal_encoding("UTF-8");

foreach ($words as $word) {
    $wordSplit = preg_split('//u', $word, null, PREG_SPLIT_NO_EMPTY);
    $strSplit = preg_split('//u', $str, null, PREG_SPLIT_NO_EMPTY);
    $wordSplit = array_filter($wordSplit, function ($x) use (&$strSplit) {
        if (in_array(strtolower($x), array_map('strtolower', $strSplit), true)) {
            $pos = array_search(strtolower($x), array_map('strtolower', $strSplit), true);
            unset($strSplit[$pos]);
            return false;
        }
        return true;
    });
    if (count($strSplit) === 0) {
        echo "$word contains all letters of $str" . PHP_EOL;
    }
}

will be helpful for those in need This is most likely caused by your database and schema setup. For example if you are using MySQL as per 10.1 Character Sets and Collations in General strings are compared using a variety of collations. Some database default to case-insensitivity string comparison collations e.g. SQL Server.
