If condition evaluates to a value that is equal to the value of one of constant-expressions, then control is transferred to the statement that is labeled with that constant-expression. The case keyword is used to compare the value of the variable with the value of the. If none of the case values match the expression, the default case is executed, ensuring that there's always a fallback action. At most one default: label may be present (although nested switch statements may use their own default: labels or have case: labels whose constants are identical to the ones used in the enclosing switch). The switch statement uses an expression to match the value of a variable. At its core, a switch statement contains a few fundamental components: the switch expression, which is evaluated, and multiple case statements, each representing a possible value. The body of a switch statement may have an arbitrary number of case: labels, as long as the values of all constant-expressions are unique (after conversions/promotions). case: and default: labels are permitted in statement and break statement has special meaning.Īttr (optional) case constant-expression : statementĪ constant expression of the same type as the type of condition after conversions and integral promotions If the (possibly converted) type is subject to integral promotions, condition is converted to the promoted type.Īny statement (typically a compound statement). The value of condition must be of integral or enumeration type, or of a class type contextually implicitly convertible to an integral or enumeration type. a declaration of a single non-array variable of such type with a brace-or-equals initializer, in this case the value of condition is the value of the declared variable.an expression, in this case the value of condition is the value of the expression.Note that any init-statement must end with a semicolon, which is why it is often described informally as an expression or a declaration followed by a semicolon. a simple declaration, typically a declaration of a variable with initializer, but it may declare arbitrarily many variables or structured bindings.I'm not to keen on PHP and as such haven't spent much time learning the syntax, I was just wondering if this & operator would be syntactically correct in a switch case, so that I could have multiple cases match one case code block. an expression statement (which may be a null statement " ") PHP multiple cases for one switch case statement.Attr (optional) switch ( init-statement (optional) condition ) statement
