Contains em PHP in return Regex

Question

I am having difficulty in searching for a specific word in text.

I tried to use the stripos method, but it throws an error because the text return is an object:

$text = preg_replace("/note:/" ,'' , $text);

if(stripos($text, "note:") !== false){
   return true
}

I need it to return if the string contains that word inside of the text to use in my if.

Answer 1

Maybe, we don't need a preg_replace and strpos would be enough:

$text = 'some word before then note: and some words after';
$word = "note:";

if (strpos($text, $word) !== false) {
    echo "YAAAY {$word} found in position: " . strpos($text, $word);
}

Output

YAAAY note: found in position: 22
