Code:Ī function with only one argument ($fname) is used in the following example. Arguments are used while exchanging values, such as during a function call. During runtime, these parameters are used to accept inputs. A user can enter as many parameters as he desires, separated by the comma (,) operator. These are used to store the values that can be executed at runtime. Parameters are the information or variables contained within the function's parenthesis. You can add as many arguments as you want just use a comma to divide them. Arguments are listed within parentheses after the function name. In PHP Function, arguments may be used to transfer information to functions. The function says "Hello welcome!" write the function's name in brackets () to invoke it.
#Php echo in showhide function example code
The beginning of the function code is indicated by the opening curly bracket.
In the above example, a function called "welcMsg()" is created. The case of a feature name is unimportant.It can begin with a letter or an underscore. A number cannot be the first character in a feature name.To invoke a function, simply type its name followed by the parenthesis.The keyword function is often used to start a function name.In PHP, the function name is any name that ends in an open and closed parenthesis. Since every logic is divided into functions, it is easier to understand the application's flow. Simple to Comprehend: The programming logic is separated using PHP Functions.You can write the logic only once and reuse it by using functions. Less Code: It saves a lot of code because the logic doesn't have to be written several times.
