Parameters
$text - The text to be searched.
$find - The search value.
$start - The search start index.
$exact - Indicates if a case sensitive search is performed.
Returns
The integer index value.
Syntax
| PHP |
|---|
public static function StrRPos(?string $text, ?string $find
, int $start = 0, bool $exact = false) : int
|
Gets the last index for the search value.
Remarks
The integer -1 is returned if the search value is not found. It can be
simply tested for success $index >= 0 or failure $index < 0.
This alternative for PHP strpos() always returns an integer.
Example
| PHP |
|---|
include_once "LJCRoot.php";
$prefix = RelativePrefix();
include_once "$prefix/LJCPHPCommon/LJCCollectionLib.php";
// $index = 13
$index = LJCCommon::StrRPos("This here is here.", "Here");
// $index = -1
$index = LJCCommon::StrRPos("This here is here.", "Here", exact: true);
