php string replace remove & add word at the end

Question

也许真的很简单，但我无法理解如何使用 str_replace 对多个短语执行以下操作：

注意：它始终是我要保留的最后一个词（即伦敦、伯明翰和苏格兰或任何其他词）。

示例短语

I Love London

Living near Birmingham

Playing by Scotland

待转化为：

In London Today

In Birmingham Today

In Scotland Today

谢谢

Answer 1

echo str_replace(array("I Love London","Living near Birmingham","Playing by Scotland"), array("In London Today","In Birmingham Today","In Scotland Today"),  "I Love London Living near Birmingham Playing by Scotland");

Answer 2

如果没有更多代码，您可能无法使用 str_replace()：

preg_match('/\w+$/', $string, $match);
echo $match[0];

或者作为示例替换：

$result = preg_replace('/.*?(\w+)$/', 'In  Today', $string);

Answer 3

使用正则表达式和preg_replace()一步完成：

print preg_replace('/.* (\w+)\W*/', 'In  today', "I love London");

我忽略了最后一个词后的任何标点符号或空格，使其比您预期的更健壮。

或者，对整个字符串列表使用相同的正则表达式：

$data = array("I love London", 
    "I live in Birmingham!",
    "Living near Birmingham!",
    "Playing by Scotland..."
    );

$results = preg_replace('/.* (\w+)\W*/', 'In  today', $data);
foreach ($results as $string)
    print $string, "\n";
