PHP检查字符串是否以给定子字符串结尾的方法
在php中,检查字符串是否以给定的子字符串结尾有多种方法。最常用的方法是使用以下函数:
$string = "This is a test string."; $substring = "test string"; if (endsWith($string, $substring)) { echo "The string ends with the given substring."; } else { echo "The string does not end with the given substring."; }
$string = "This is a test string."; $substring = "test string"; $result = substr_compare($string, $substring, -strlen($substring)); if ($result == 0) { echo "The string ends with the given substring."; } else { echo "The string does not end with the given substring."; }
$string = "This is a test string."; $substring = "test string"; $pattern = "/$substring$/"; if (preg_match($pattern, $string)) { echo "The string ends with the given substring."; } else { echo "The string does not end with the given substring."; }
上述方法都可以在PHP中有效地检查字符串是否以给定的子字符串结尾。具体选择哪种方法取决于您的特定需求和应用程序的性能要求。
