Ce este un operator? Un raspuns cat se poate de simplu 4 + 6 = 9. Aici 4 si 5 sunt operanzi, iar + este operator.
PHP suporta urmatoprii operatori:
-
- Operatori aritmetici
- Operatori de comparatie
- Operatori logici
- Operatori de atribuire
Operatori conditionali (ternari)
Operatori Aritmetici
Presupunem ca A este 10 si B este 20
| Operator | Descriere | Exemplu |
| + | Adunare | A + B = 30 |
| – | Scadere | A – B = -10 |
| * | Inmultire | A * B = 200 |
| / | Impartire | B / A = 2 |
| % | Modul | B % A = 0 |
| ++ | Incrementare | A++ = 11 |
| — | Decrementare | A– = 9 |
Operatori de comparatie
| Operator | Descriere | Exemplu |
| == | Verifica o egalitate | (A == B) va da FALSE |
| != | Verifica o inegalitate | (A != B) va da TRUE |
| > | Verifica daca valoarea din stanga este mai mare. | (A > B) va da FALSE |
| < | Verifica daca valoarea din dreapta este mai mare. | (A < B) va da TRUE |
| >= | Verifica daca valoarea din stanga este mai mare sau egala. | (A >= B) va da FALSE |
| <= | Verifica daca valoarea din dreapta este mai mare sau egala. | (A <= B) va da TRUE |
Operatori Logici
| Operator | Descriere | Exemplu |
| AND | Daca ambii operanzi sunt TRUE atunci rezultatul este TRUE | (A AND B) va da TRUE |
| OR | Daca unul dintre operanzi este TRUE atunci rezultatul este TRUE | (A OR B) va da TRUE |
| && | Este exact ca AND. | |
| || | Este exact ca OR. | |
| ! | Acest operator se numeste NOT si este folosit pentru a inversa logica celorlalti operatori.Daca o conditie este TRUE atunci NOT o face FALSE | !(A AND B) va da FALSE |
Operatori de atribuire
| Operator | Descriere | Exemplu |
| = | Operator simplu de atribuire | C = A + B inseamna ca C este egal cu rezultatul adunarii dintre A si B |
| += | Aduna operandul din stanga la cel din dreapta. | C += A este echivalent cu C = C + A |
| -= | Scade operandul din stanga din cel din dreapta | C -= A este echivalent cu C = C – A |
| *= | -//- | C *= A este echivalent cu C = C * A |
| /= | -//- | C /= A este echivalent cu C = C / A |
| %= | -//- | C %= A este echivalent cu C = C % A |
Operatori conditionali
Mai exista un operator numit operator conditional. Acesta evalueaza o expresia daca este TRUE sau FALSE si apoi executa una din doua coduri date in functie de rezultatul evaluarii.Exemplu:
<?php
$a = 10;
$b = ( ($a == 10)? "Da, a este 10":"Nu, a nu este 10");
//este similar cu:
if( $a == 10 ){
$b = "Da, a este 10";
}else{
$b = "Nu, a nu este 10";
}
