![]() While it's understandable that the PHP developers don't consider this a bug, or don't consider it a bug worth their time, jsimlo was right to point out that mixing alternative if syntaxes might lead to unexpected results. Instead of concluding that the else statement was intended to match the if($b) statement (and erroring out), the parser could match the else statement to the if($a) statement, which shares its syntax. In other words, one would expect that this would work: The following is illegal (as it should be):īut since the two alternative if syntaxes are not interchangeable, it's reasonable to expect that the parser wouldn't try matching else statements using one style to if statement using the alternative style. The parser doesn't handle mixing alternative if syntaxes as reasonably as possible. You may be familiar with some of the comparison operators in PHP, such as the ternary operator :, the null coalescing operator, and the spaceship operator <>.It is used to assign a value to a variable based on a condition. Of elseif in a single word becomes necessary. Shorthand comparison, also known as the ternary operator, is a shorthand way of writing an if-else statement in PHP. Will only be considered exactly the same when using curly bracketsĪs in the above example. Preceding if expression and any preceding The elseif statement is only executed if the Is that both would result in exactly the same behavior. PHP Conditional Statements: The PHP If statement is used to test a condition and then based on the results, if the condition is TRUE then a particular block. Like else, it extends an if statement to execute a different statement in case the original if expression evaluates to false. Is slightly different (the same behavior as C) but the bottom line PHP Manual Language Reference Control Structures Change language: Submit a Pull Request Report a Bug elseif/else if (PHP 4, PHP 5, PHP 7, PHP 8) elseif, as its name suggests, is a combination of if and else. In PHP, it's possible to writeĮlse if (in two words) and the behavior would be identical There may be several elseifs within the sameĮlseif expression (if any) that evaluates to expression2 - is an expression that will be evaluated if condition is false.Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?

Only use Ternary operators for a single condition in PHP, and you may execute multiple actions within that condition. ![]() PHP if Statement if Statement is used to execute some part of code when only one condition is true. ![]() ifelseifelse statement to implement the complex conditional logic you can use if inside if or if inside else. condition - is an expression that evaluates to a boolean value ( true or false). ifelse statement to execute some part of code when a condition is true and execute another part of code when the condition is false.The syntax for ternary operator can be represented as follows: condition ? expression1 : expression2 ![]() The ternary ( ?:) operator is a conditional operator that allows to shorten if/ else structures and decrease the length of code. //Make the variable today hold the value Thursday today Thursday //Test if the variable today is Friday, //if it is then we can go to the pub for lunch. ![]()
