在你的特殊情况下，Regex实际上更快.但这很可能是因为您将EndsWith与许多OR和冗余ToString()一起使用。
function endsWith($haystack, $needle) { $length = strlen($needle); if ($length == 0) { return true; } return (substr($haystack, -$length) === $needle); }如果不想使用regex,请使用此选项。相关讨论 +1这比公认的答案更清楚。另外,在endsWith()的最后一行中不需要$length。 变量名不清楚...
On first look that really seems to me the same as regexps with % instead of \ for escape. I do like their () solution for capturing position though. Contributor stedolan commented Nov 8, 2013 String processing in jq is not good at the moment. I really want to implement a PEG-style...

Learn to check if a string starts with, ends with, or both with a specified substring using the regex and built-in methods, and array slicing.
Java regex word boundary example. Use regular expression word boundaries to find matching lines which start with or end with a certain words. Sometimes we have a requirement where we have to filter out lines from logs, which start from a certain word OR end with a certain word. In this Ja...

除了使用any()和endswith()结合的方法外,还可以使用正则表达式(通过re模块)来处理更复杂的字符串后缀检查问题。正则表达式提供了强大的模式匹配功能,但相对来说语法可能更复杂一些。 例如,使用正则表达式检查多个后缀: python import re def ends_with_any_regex(s, suffixes): pattern = re.compile(f'({"|".jo...
