php 找到字符串中的内容后如何添加句子？

Question

假设我有这个字符串。

$string = "While it has long been disputed, 
it's estimated that Julius Caesar was born in 
Rome on July 12 or 13, 100 BC. 
He hailed from Roman aristocrats[his family was far from rich]. 
When Caesar was 16 his father, Gaius Caesar, died. 
He remained close to his mother, Aurelia."

我想在 $string 中搜索 [his family was far from rich] 并在 [his family was far from rich] 之后插入一个新行 from www.wiki.com。

Answer 1

如果内容是静态的并且您想替换每个出现的地方，请使用 str_replace。

$search = '[his family was far from rich]';
echo str_replace($search, "\n" . $search . 'from www.wiki.com', $string);

Answer 2

也许你想要这样的东西？


$string = "While it has long been disputed, 
it's estimated that Julius Caesar was born in 
Rome on July 12 or 13, 100 BC. 
He hailed from Roman aristocrats[his family was far from rich]. 
When Caesar was 16 his father, Gaius Caesar, died. 
He remained close to his mother, Aurelia.";</p>

<p>$tofind="[his family was far from rich]";</p>

<p>$newstring= str_replace($tofind,$tofind." from www.wiki.com",$string);</p>

<p>echo $newstring;</p>

<p></pre>
