* bool $keep_character determines whether or not to keep the character. * string $side determines whether text to the left or the right of the character is returned. * string $string the string to search through. * string $character the character to search for. If the substring is not found it returns false. * $cwd_relative = cut_string_using_last('/', $example, 'right', false) The strpos() function returns the position of the first occurrence of a substring in a string. * $cwd_relative = cut_string_using_last('/', $example, 'right', true) * $cwd_relative = cut_string_using_last('/', $example, 'left', false) * $cwd_relative = cut_string_using_last('/', $example, 'left', true)

Setting character encoding in 4th parameterĮcho mb_strpos($str, 'ПХП', 3, 'UTF-8') //17Įxample: Using mb_stripos, mb_strrpos, and mb_strripos 
mb_strripos() works same as strripos().If the $encoding parameter is omitted or null, the internal character encoding will be used. Use the following functions if you are dealing with multibyte strings, these functions accept an additional parameter $encoding for the character encoding. Int $offset = 0, ?string $encoding = null bool(false)*/ Find the position of a string in a multibyte string about prepared statements instead, and use PDO or MySQLi. They are no longer maintained and are officially deprecated. The strripos() function works same as strrpos() function, except it is case insensitive. 1 Answer Sorted by: 1 First, please, don't use mysql functions in new code. Strripos(string $haystack, string $needle, int $offset = 0): int|false Prints: PHP found at index 24 strripos() 
Strrpos(string $haystack, string $needle, int $offset = 0): int|false The stripos() function works same as strpos() function, except it is case insensitive.
Stripos(string $haystack, string $needle, int $offset = 0): int|false Find the position of a string in a multibyte string.strripos works same as strrpos but it ignores the case.strrpos finds the last occurrence of substring and returns its position.stripos works same as strpos but it ignores the case.I have this query that I am using: Select substringindex (refurl,'gclid',1) as refurl, Count () from leads group by substringindex (refurl,'gclid',1) But for the delimiter I want it to clear off gclid or &gclid, is this. strpos finds the first occurrence of substring and returns its position. I am trying to remove some information off urls that are placed into my database.When looking for substrings in strings, the following functions are used:
