What is the purpose of using the patternSyntax in PHP for search queries?

The patternSyntax parameter in PHP search queries is used to specify the type of regular expression syntax to be used when performing a search. This can help ensure that the search query is interpreted correctly and produces accurate results. 

// Example of using patternSyntax parameter in a search query
$searchTerm = "example";
$pattern = "/$searchTerm/i"; // Using 'i' flag for case-insensitive search
$patternSyntax = 'pcre';
$matches = preg_grep($pattern, $arrayToSearch, $patternSyntax);

// Output the search results
foreach ($matches as $match) {
    echo $match . "<br>";
}
