在PHP中，常用的選擇結構語句有以下幾種：
if (condition) {
// code to be executed if condition is true
} else {
// code to be executed if condition is false
}
switch (variable) {
case value1:
// code to be executed if variable is equal to value1
break;
case value2:
// code to be executed if variable is equal to value2
break;
// ...
default:
// code to be executed if variable does not match any of the cases
}
$variable = (condition) ? value1 : value2;
if (condition1) {
// code to be executed if condition1 is true
} elseif (condition2) {
// code to be executed if condition1 is false and condition2 is true
} else {
// code to be executed if both condition1 and condition2 are false
}
以上是PHP中常用的選擇結構語句，可以根據具體的需求選擇合適的語句來實現不同的邏輯。
