In case you are using an older version of PHP (e.g. PHP 7), you can define and use the following function:
function endsWith($haystack, $needle) {
$length = strlen($needle);
return $length > 0 ? substr($haystack, -$length) === $needle : true;
}
str_ends_with
(PHP 8)
str_ends_with — Checks if a string ends with a given substring
Descrição
str_ends_with(string
$haystack, string $needle): bool
Performs a case-sensitive check indicating if
haystack ends with needle.
Parâmetros
-
haystack -
The string to search in.
-
needle -
The substring to search for in the
haystack.
Valor Retornado
Returns true if haystack ends with
needle, false otherwise.
Exemplos
Exemplo #1 Using the empty string ''
<?php
if (str_ends_with('abc', '')) {
echo "All strings end with the empty string";
}
?>
O exemplo acima irá imprimir:
All strings end with the empty string
Exemplo #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';
}
?>
O exemplo acima irá imprimir:
The string ends with 'fence' "fence" was not found because the case does not match

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));
}
}
?>

Wordpress 5.9 RC3 does it this way:
<?php
if ( ! function_exists( 'str_ends_with' ) ) {
function str_ends_with( $haystack, $needle ) {
if ( '' === $haystack && '' !== $needle ) {
return false;
}
$len = strlen( $needle );
return 0 === substr_compare( $haystack, $needle, -$len, $len );
}
}
?>
I suppose the compiler optimizes for the fact that `substr_compare()` is only being used for equality, not comparison ( <0, >0 ).
