PHP :: If…Else Statements<\/p>\n

Date Posted<\/strong> : 25-Oct-2018<\/strong><\/p>\n

Conditional statements are used to perform different actions based on different conditions.
\nConditional Statements
\nVery often when you write code, you want to perform different actions for different decisions.
\nYou can use conditional statements in your code to do this.
\nIn PHP we have the following conditional statements:<\/p>\n

if statement – use this statement to execute some code only if a specified condition is true
\nif…else statement – use this statement to execute some code if a condition is true and another code if the condition is false
\nif…elseif….else statement – use this statement to select one of several blocks of code to be executed<\/p>\n

The if Statement:<\/strong>
\nUse the if statement to execute some code only if a specified condition is true.
\nSyntax<\/strong>
\nif (condition) code to be executed if condition is true;
\nThe following example will output “Have a nice weekend!” if the current day is Friday:<\/p>\n

<html>\r\n<body>\r\n\r\n<?php\r\n$d=date(\"D\");\r\nif ($d==\"Fri\") echo \"Have a nice weekend!\";\r\n?><\/pre>\n
The if…else Statement<\/strong>:
\nUse the if….else statement to execute some code if a condition is true and another code if a condition is false.
\nSyntax
\nif (condition)
\ncode to be executed if condition is true;
\nelse
\ncode to be executed if condition is false;<\/p>\n
<\/body>
\n<\/html>
\nNotice that there is no ..else.. in this syntax. The code is executed only if the specified condition is true.<\/p>\n
Example<\/strong>
\nThe following example will output “Have a nice weekend!” if the current day is Friday, otherwise it will output “Have a nice day!”:<\/p>\n
<html>\r\n<body>\r\n\r\n<?php\r\n$d=date(\"D\");\r\nif ($d==\"Fri\")\r\n  echo \"Have a nice weekend!\";\r\nelse\r\n  echo \"Have a nice day!\";\r\n?>\r\n\r\n<\/body>\r\n<\/html><\/pre>\n
If more than one line should be executed if a condition is true\/false, the lines should be enclosed within curly braces:<\/p>\n
<html>\r\n<body>\r\n\r\n<?php\r\n$d=date(\"D\");\r\nif ($d==\"Fri\")\r\n  {\r\n  echo \"Hello!<br \/>\";\r\n  echo \"Have a nice weekend!\";\r\n  echo \"See you on Monday!\";\r\n  }\r\n?>\r\n\r\n<\/body>\r\n<\/html><\/pre>\n
The if…elseif….else Statement:<\/strong>Use the if….elseif…else statement to select one of several blocks of code to be executed.
\nSyntax
\nif (condition)
\ncode to be executed if condition is true;
\nelseif (condition)
\ncode to be executed if condition is true;else
\ncode to be executed if condition is false;
\nExample<\/strong>
\nThe following example will output “Have a nice weekend!” if the current day is Friday, and “Have a nice Sunday!” if the current day is Sunday. Otherwise it will output “Have a nice day!”:<\/p>\n
<html>\r\n<body>\r\n\r\n<?php\r\n$d=date(\"D\");\r\nif ($d==\"Fri\")\r\n  echo \"Have a nice weekend!\";\r\nelseif ($d==\"Sun\")\r\n  echo \"Have a nice Sunday!\";\r\nelse\r\n  echo \"Have a nice day!\";\r\n?>\r\n\r\n<\/body>\r\n<\/html><\/pre>\n
