What are best practices for handling warnings like "No ending matching delimiter '>' found" in PHP preg_match?

When encountering a warning like "No ending matching delimiter '>' found" in PHP preg_match, it typically means that the regular expression pattern is missing a closing delimiter. To solve this issue, make sure that the regular expression pattern is enclosed within appropriate delimiters, such as forward slashes (/) or hash symbols (#). 

// Incorrect regular expression pattern without delimiters
$pattern = '<div class="example">';

// Corrected regular expression pattern with delimiters
$pattern = '/<div class="example">/';
