You can do this with regular expression or simple string function

$string = 'MASTER_LECTURE.NAME';

$string_replace = 'MASTER_LECTURE';

// Regular expression
preg_replace('/'.preg_quote($string_replace).'/is', '', $string);

// String function
$string = str_replace($string_replace, '', $string);

nice @delphist. Can you show me the pattern when word MASTER_LECTURE will dynamic depend on string that we submit?

if you are only replacing a string and not a pattern you can use str_replace

you do not need a formula. Its just str_replace($search,$replace, $subject). if its really a word and not a patter you should use this since its lighter
