In PHP we have the following conditional statements:if statement - executes some code if one condition is true if...else statement - executes some code if a condition is true and another code if that condition is false if...elseif...else statement - executes different codes for more than...

There may be several elseifs within the same if statement. The first elseif expression (if any) that evaluates to true would be executed. In PHP, it's possible to write else if (in two words) and the behavior would be identical to the one of elseif (in a single word). The ...

在编程中,if-else语句用于根据条件的真假来执行不同的代码块。if语句用于判断条件是否为真,如果为真则执行if代码块中的语句;如果条件为假,则执行else代码块中的语句。 以下是一个示例代码: 代码语言:txt 复制 if condition: # 如果条件为真,执行这里的代码 statement1 statement2 else: # 如果条件为假,执行...
使用else创建SQL和PHP IF语句的方法如下: 在SQL中,可以使用IF语句来实现条件判断和分支控制。IF语句的基本语法如下: 代码语言:txt 复制 IF(condition, true_statement, false_statement) 其中,condition是一个条件表达式,true_statement是当条件为真时执行的语句,false_statement是当条件为假时执行的语句。
}elsedo{ }while(!$a); 因为在PHP的语法设计中,if else本质上是: if_stmt: if_stmt_without_else T_ELSE statement 也就是说,else后面可以接一切statement,如果条件不成立,执行流就跳到else后面的statement,而while, switch都可以归约为statement。
