Avvertimento

Questa funzione SPERIMENTALE. Ovvero, il comportamento di questa funzione, il nome di questa funzione, in definitiva tutto ci che documentato qui pu cambiare nei futuri rilasci del PHP senza preavviso. Siete avvisati, l'uso di questa funzione a vostro rischio.

dbplus_find() will place a constraint on the given relation. Further calls to functions like dbplus_curr() or dbplus_next() will only return tuples matching the given constraints.

Constraints are triplets of strings containing of a domain name, a comparison operator and a comparison value. The constraints parameter array may consist of a collection of string arrays, each of which contains a domain, an operator and a value, or of a single string array containing a multiple of three elements.

The comparison operator may be one of the following strings: '==', '>', '>=', '<', '<=', '!=', '~' for a regular expression match and 'BAND' or 'BOR' for bitwise operations.
