When searching for specific data in PHP scripts, such as in the case of 'art', one strategy to ensure accurate search results is to use the strpos() function to check if the keyword exists within the data being searched. This function returns the position of the first occurrence of a substring in a string, or false if the substring is not found.

$data = "This is some sample data containing the word 'art'";
$keyword = 'art';

if(strpos($data, $keyword) !== false){
    echo "Keyword found in data";
} else {
    echo "Keyword not found in data";
}
