PHP-检测字符串之间的空格 [英] PHP - detect whitespace between strings

问题描述

如何检测字符串中的空白?例如，我有一个名称字符串，例如:

How would I go about detecting whitespace within a string? For example, I have a name string like:

简·多伊"

请记住，我不想修剪或替换它，只需检测第一和第二个字符串之间是否存在空格.

Keep in mind that I don't want to trim or replace it, just detect if whitespace exists between the first and second string.

推荐答案

使用Josh建议的preg_match:

Use preg_match as suggested by Josh:

<?php

$foo = "Dave Smith";
$bar = "SamSpade";
$baz = "Dave\t\t\tSmith";

var_dump(preg_match('/\s/',$foo));
var_dump(preg_match('/\s/',$bar));
var_dump(preg_match('/\s/',$baz));

胜利:

int(1)
int(0)
int(1)
