That in combination with a Router library would probably be the most useful to address your actual needs. strpos (PHP 4, PHP 5, PHP 7, PHP 8) strpos Find the position of the first occurrence of a substring in a string Description strpos ( string haystack, string needle, int offset 0 ): intfalse Find the numeric position of the first occurrence of needle in the haystack string. PHP strpos function is using for checking the occurrence position of a character or string within a string.It will return the numeric position number of the. This way, if your explicit matching logic fails inside the method, if for some reason new Haystack($_GET) = new Haystack($needle) is true, the non-matching property "$isMain" will ensure they are not evaluated as equal.Īgain, I would re-examine why you'd want to do this in the first place for this particular situation traditionally, Composer is a dependency management tool which would be used to include various scripts you need via a PSR autoload standard. Public function _construct(string $value, bool $isMain = true)įinal public function contains($needle): Haystack If you do, and are not using a version of PHP which supports nullable return types (ie a method signature of public function contains(string $substring): ?Haystack) then your class would have to elaborate to reflect that. Use true inside the switch and check in every case if the strpos() result is false.
#Php switch case strpos how to
In this tutorial, I will show how to use switch and case with the strpos() function in PHP. In many cases, the switch statement may be a perfect fit for this.
#Php switch case strpos code
You can, of course, generously garnish this code with typehints. Sometimes we need to check multiple strings for the presence of a specific piece of text. If (strpos($this->value, $needle) != false) Strpos(), and its case-insensitive sibling stripos(), returns the index of the first occurrence of a substring within a string. So just create methods which either return $this, or nothing at all. The idea is to keep in mind that a switch statement will execute any code where $switch = $case (a loose match). In my opinion, it's a code smell if you're including scripts via GET variables, but you can do this elegantly using a value class with methods whose logic return the value object itself if true.
