replace - geany find special substring -

i have lot of php files , want find every occurance of

htmlentities(some var); 

in geany, , don't want

htmlentites(some var, ent_quotes); 

got found, has like:

htmlentities(...); 

because dots stand undefined character, able find specified lenght. correct syntax find undefined length substring?

you can use regular expressions inside search , replace dialogs. little depends on system (e.g. grep etc.) , looking in detail, here deeplink manual.
