PHP's strlen function behaves differently than the C strlen function in terms of its handling of null bytes ('\0'). In PHP, a null byte in a string does NOT count as the end of the string, and any null bytes are included in the length of the string. For example, in PHP: strlen( "te\0st" ) = 5 In C, the same call would return 2.

The substr_count() function counts the number of times a substring occurs in a string. Note: The substring is case-sensitive. Note: This function does not count overlapped substrings (see example 2).
substr_count() returns the number of times the needle substring occurs in the haystack string. Please note that needle is case sensitive. Note: This function doesn't count overlapped substrings. See the example below!
count (Countable | array $value, int $mode = COUNT_NORMAL): int. Counts all elements in an array when used with an array. When used with an object that implements the Countable interface, it returns the return value of the method Countable::count ().
28 kwi 2010 · mb_strlen () with mb_internal_encoding ('UTF-8'). strlen (): Returns the number of bytes rather than the number of characters in a string. mb_strlen (): Returns the number of characters in a string having character encoding. A multi-byte character is counted as 1.
The substr_count() function in PHP is used to count the number of occurrences of a substring within a string. This function is useful when working with text-based applications where the frequency of certain substrings needs to be determined.
PHP strlen() function is used to count the length of a given string or check the number of characters in a string. Here 'str' means string, and 'len' means length. It only takes one parameter, which is certainly imperative to implement this function.
