如何检查文本框是否包含一个或两个单词 - PHP-How to check if the textbox contains one word or two?

PHP-How to check if the textbox contains one word or two?

现在我想检查这个文本框是否包含一个或两个单词，例如

 if ($_POST['mytext'] == two words){
 echo "That is Perfect";
} else{
echo "We don't accept this";
}

and I tried

 if ($_POST['mytext'] > 1){
 echo "That is Perfect";
} else{
echo "We don't accept this";
}

，它没有工作

这就是我的意思，那么怎么做呢?希望能找到一种方法。

谢谢

如果将两个单词定义为"一些字符后跟一个空格后跟一些字符"那么您可以这样做:

$mytext = $_POST["mytext"];
$parts = explode(" ", $mytext);
if (count($parts) !== 2) {
    throw new Exception("too many or too little!");
}
if (strlen($parts[0]) === 0 || strlen($parts[1]) === 0) {
    throw new Exception("not enough characters!");
}

请记住，这允许像"@ !"

这样的字符串

使用str_word_count():

if (str_word_count($_POST['mytext']) > 1){
  echo "That is Perfect";
} else{
  echo "We don't accept this"; 
}

你可以使用

`substr_count('some text', ' ');

它将返回空格数，

try this

 $text= preg_split(" ",$_POST['mytext']);
   if (count($text) > 1){
     echo "That is Perfect";
    } else{
       echo "We don't accept this";
    }
