#Php if else codeYou may copy the code and try it in your PHP editor. If it is some other number the PHP else statement part will execute. If the given number is 3, it will be evaluated as true in the if statement, so the statement inside the if statement will execute. Only, the if.else statement is used in the example. In the example, I have simply declared a variable and assigned it a numeric value. #Php if else how toI will explain both with visual examples in this tutorial, so you may understand how to use if.else with HTML or other web elements, as such PHP is generally used for web based projects.Ī simple example to start with – the if.elseīefore going to user selection based execution of a block in the if.else statement, in this example, I will simply use a static value to show how it works, to give an idea if you are a beginner. ‘try-catch’ communicate between the data with the conditions and the system.Note: If you have multiple lines to execute, enclose each block in curly brackets. ‘if-else’ communicate between the data provided to the program and the condition. ‘try-catch’ is more time consuming than ‘if-else’. ‘if-else’ is less time consuming than ‘try-catch’. In ‘try-catch’ we don’t have to define each ‘try’ block with a ‘catch’ block. Or we need to define another condition with command ‘else if’. In ‘if-else’, we have one else block corresponding to one if block. In ‘try-catch’ the codes to handle the exceptions and what exception to be handled, that are easily readable. In ‘if-else’ the conditions and the codes inside the blocks are got mixed, so that it becomes unreadable if there is many ‘if-else’ blocks. ‘try-catch’ handles system generated errors like, if a array is out of bound, divide by zero etc. In case of ‘try-catch’, the system will check the system generated errors or exception during a executing process or a task.Ĭonditions are manually generated in ‘if-else’. ‘if-else’ use to handle different conditions using condition checking. ‘try’ is a section where a code is defined for tested whether the code generates an unexpected result while executing, if any unexpected result found catch block is executed to handle that situation. It checks any condition is true or not, if true then execute the code inside the if block otherwise execute else block. Output: Exception: denominator is a stringīrief discussion about the differences of ‘try-catch’ and ‘if-else’ in PHP: if-else In if-else, conditions are manually generated based on the task. In many cases there are many corner cases which must be checking during a execution but “if-else” can only handle the defined conditions. if-else catch errors as a conditional statement. Actually this block of code handles the exceptions.Įrror Handling: Mainly if-else block is used to handle errors using condition checking. catch: It is a section where another block of code is defined, which is executed if any unexpected result generates in the try block.try: It is a section where a block of code is defined for tested whether the code generates an unexpected result while executing.else: If the condition is “false” which is checked by the if block, then else block executes the other code within it.if: It checks if any condition is “true” or not, if it is true then it executes the code inside the if block.How to Upload Image into Database and Display it using PHP ?.How to execute PHP code using command line ?.How to delete an array element based on key in PHP?.How to pop an alert message box using PHP ?.ReactJS | Setting up Development Environment.
