php str_ends_with() end of string

With the release of PHP8, new functions and features are constantly being introduced. One of the noteworthy functions is str_ends_with(). This function can be used to determine whether a string ends with a specific string, which is often used in actual development.

In this article, we will discuss the use of str_ends_with() function and some precautions. First, we need to understand the syntax structure of this function:

bool str_ends_with (string $haystack, string $needle)

This function accepts two parameters: $haystack and $needle. Among them, $haystack represents the string to be checked, and $needle represents the string to be queried. The return value of the function is a Boolean value, which returns true if $haystack ends with $needle, otherwise it returns false.

The following is an example of using the str_ends_with() function, which queries whether the $haystack string ends with "end":

$haystack = "This is the end";
$needle = "end";
if (str_ends_with($haystack, $needle)) {

}
?>

Note: The

  1. str_ends_with() function is a new function added in PHP8 , cannot be used in lower versions of PHP. If you want to use this function, be sure to upgrade to PHP8 or higher.
  2. When using the str_ends_with() function, please ensure that the value of the $needle parameter is not included in the $haystack string. Otherwise, the function will return incorrect results. For example, if the $needle string is "is" and the $haystack string is "This is the end", then the function will return true, which is obviously wrong.
  3. str_ends_with() function is case-sensitive. For example, if the $haystack string is "Hello World" and the $needle string is "world", the function will return false. If case-insensitive matching is required, both parameters need to be converted to lowercase or uppercase before using this function.

Summary:

The str_ends_with() function is a convenient new function that can help us quickly and accurately determine the end of a string during string operations. In actual development, we can use it to check file extensions, check whether the URL address ends with a specific string, etc., making our program more robust.
