用于验证输入的正则表达式正则表达式:两个单词之间有空格 [英] Regular Expression regex to validate input: Two words with a space between

问题描述

我需要使用正则表达式来验证一个带有 php 的字段，该字段必须有两个由空格分隔的单词，例如:First Last"，但我找不到适合我的目的，有人可以帮助我吗?

i need to use a regular expression to validate a field with php that has to have two words separated by a space like: "First Last" but i cant find one that fits my purposes, can anyone help me?

我做过的最好的是 ^[a-zA-Z0-9_\s]*$ 但有了这个我可以有不止一个空间和领域的任何地方，我只想要字之间.有人可以帮我吗?

The best i've done is ^[a-zA-Z0-9_\s]*$ but with this i can have more than one space and anywhere in the field and i want only between the words. Can anyone help me?

推荐答案

^\w+\s\w+$ 之类的东西应该适用于这种情况.但是您不一定需要为此使用正则表达式，您可以使用 explode().

Something like ^\w+\s\w+$ ought to work for this case. But you don't necessarily need to use regular expressions for this, you could just use explode().
