    str_ends_with

    (PHP 8)

    str_ends_with — Checks if a string ends with a given substring

    Description

    str_ends_with(string $haystack, string $needle): bool

    Performs a case-sensitive check indicating if haystack ends with needle.

    Parameters

    haystack

    The string to search in.

    needle

    The substring to search for in the haystack.

    Return Values

    Returns true if haystack ends with needle, false otherwise.

    Examples

    Example #1 Using the empty string ''

    <?php
    if (str_ends_with('abc', '')) {
    echo     "All strings end with the empty string";
    }
    ?>

    The above example will output:

    All strings end with the empty string

    Example #2 Showing case-sensitivity

    <?php
    $string     = 'The lazy fox jumped over the fence';

    if (    str_ends_with($string, 'fence')) {
    echo     "The string ends with 'fence'\n";
    }

    if (    str_ends_with($string, 'Fence')) {
    echo     'The string ends with "Fence"';
    } else {
    echo     '"Fence" was not found because the case does not match';
    }

    ?>

    The above example will output:

    The string ends with 'fence'
"Fence" was not found because the case does not match

    In case you are using an older version of PHP, you can define and use the following function:

    function endsWith($haystack, $needle) {
    $length = strlen($needle);
    return $length > 0 ? substr($haystack, -$length) === $needle : true;
    }

    In PHP7 you may want to use:

    if (!function_exists('str_ends_with')) {
    function str_ends_with($str, $end) {
    return (@substr_compare($str, $end, -strlen($end))==0);
    }
    }

    AFAIK that is binary safe and doesn't need additional checks.

    this is the fastest php7-implementation i can think of, it should be faster than javalc6 and Reinder's implementations, as this one doesn't create new strings (but theirs does)

    <?php
    if (! function_exists('str_ends_with')) {
    function     str_ends_with(string $haystack, string $needle): bool
    {
    $needle_len = strlen($needle);
    return (    $needle_len === 0 || 0 === substr_compare($haystack, $needle, - $needle_len));
    }
    }
    ?>
