我想将结果保存为变量而不是在数组中打印它们

Question

I am using the following code that gets what is between <p> and </p>. Instead of displaying the result in an array how can I save every paragraph in a new variable ? Thank you!

Answer 1

I think that

foreach ($matches as $match) {
    doSomething with $match[1];
}

should do the trick. $matches should contain a list of each match, where a match consist of the whole string matched and then the groups. Since there is only one group in each match that you are interested, $match[1] should give you the content of the paragraph, $match[0] the whole paragraph with the <p> tags on it.
