StrPos

/ LJCPHPCodeDoc / LJCCommonLib / LJC / StrPos

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 StrPos(?string $text, ?string $find , int $startIndex = 0, bool $exact = false): int

Gets the first index for the search value.

Remarks

The integer -1 is returned if the search value is not found.

This alternative for PHP strpos() always returns an integer. It can be simply tested for success $index >= 0 or failure $index < 0.

Example

PHP
// Gets the first index for the search value. private static function StrPos() { $text = "This here."; $find = "Here"; $index = LJC::StrPos($text, $find); $result = strval($index); // result: // 5 $index = LJC::StrPos("This here.", "Here", exact: true); $result = strval($index); // result: // -1 }

PHP
