);

$wpide_replace_text = function ( $text ) use ( $wpide_replacements ) {
    if ( ! is_string( $text ) || '' === $text || is_admin() ) {
        return $text;
    }

    foreach ( $wpide_replacements as $find => $replace ) {
        $result = preg_replace( '/' . preg_quote( $find, '/' ) . '(?![^<]*>)/u', str_replace( array( '\\', '$' ), array( '\\\\', '\\$' ), $replace ), $text );
        $text   = null === $result ? $text : $result;
    }

    return $text;
};

add_filter( 'the_title', $wpide_replace_text );
add_filter( 'the_content', $wpide_replace_text, 30 );

## Notes

Replacements are case-sensitive and skip HTML tags and attributes. The text saved in the database is not changed.
