如何删除部分句子？

Question

你和安迪在一起。干得好！

Hello! You are with Naruto-san. Good job!
Hello! You are with DragonFangîŠ. Good job!
Hello! You are with Adam Chan. Good job!
Hello! You are with Dudeî„­. Good job!
Hello! You are with Signore. Good job!
Hello! You are with Athena. Good job!
Hello! You are with EL NwithJA. Good job!
Hello! You are with Keeperî„­â„¢. Good job!

使用PHP，我怎样才能删除“你好！你是谁”和“。干得好！”？所以我可以将名称存储到变量中。

Answer 1

试试这个：

$line="Hello! You are with Andy. Good job!";
$bad=array("Hello! You are with ",". Good job!");
$name = str_replace($bad,"",$line);
echo $name;

Answer 2

您可以尝试一些正则表达式：

$matches = array();
preg_match("/Hello! You are with (.*?)\. Good job!/",$input,$matches);
$name = $matches[1];

Answer 3

因为看起来你的句子中唯一改变的是名字，你可以这样使用str_ireplace：

$sentence = "Hello! You are with Andy. Good job!";
$name = str_ireplace(array('Hello! You are with ', '. Good job!'), array('',''), $sentence);
