Simple php process control switch instance, phpswitch
The switch allows you to select multiple possible results of a scalar (expression.
Syntax:
Switch (expr) {case result1: statement1 break; case result2: statement2 break ;...... Default: statement}
The system calculates the expr value and selects the following execution statement based on the calculation result (result1, result2, etc.). If all the case results do not match, the statement in default is executed.
Example:
<? Php switch ($ x) {case 0: echo "x equals 0"; break; case 1: echo "x equals 1"; break; case 2: echo "x equals 2"; break; default: echo "x is neither 1 nor 2 nor 0" ;}?>
Prompt
• Multiple case conditions can be judged.
• The results after case are not limited to numbers, but can also be characters or other types supported by PHP
• Default is not required
