PHP /正则表达式获取一组双引号之间的内容

Question

Update to my question: My goal overall is to split the string into 4 parts that I can access later.

1. value
2. =
3. "
4. result of the html inside the first and last " "

Here is an example of what i'm trying to do:

// My string (this is dynamic and will change, this is just an example)

$string = 'value="<p>Some text</p> <a href="#">linky</a>"';

// Run the match and spit out the results

preg_match_all('/([^"]*)(?:\s*=\s*(\042|\047))([^"]*)/is', $string , $results);

// Here is the array I want to end up with

Array
(
[0] => Array
    (
        [0] => value="<p>Some text</p><a href="#">linky</a>"
    )

[1] => Array
    (
        [0] => value
    )

[2] => Array
    (
        [0] => "
    )

[3] => Array
    (
        [0] => <p>Some text</p><a href="#">linky</a>
    )
)

Basically the double quotes on the link are causing me some trouble so my first though was to do [^"]$ or something to have it just run until the last double quote, but that isn't getting me anywhere. Another idea I had was maybe process the string in PHP to strip out any inner quotes, but i'm not sure ho to go about this either.

Hopefully I'm being clear, it is pretty late and i've been at this far too long!

Answer 1

Try this regex

$string = 'value="<p>Some text</p> <a href="#">linky</a>"';
$regex = '/([^"]*)(?:\s*=\s*(?:\042|\047))(.*)(?:\042|\047)(?:[^"]*)/is';
preg_match_all($regex, $string , $results);

it gives following result.

Array(3) {
  [0]=>
  Array(1) {
    [0]=>
    string(46) "value="<p>Some text</p> <a href="#">linky</a>""
  }
  [1]=>
  Array(1) {
    [0]=>
    string(5) "value"
  }
  [2]=>
  Array(1) {
    [0]=>
    string(38) "<p>Some text</p> <a href="#">linky</a>"
  }
}

如果您不花一点时间更改html，可以尝试以下操作：

$string = 'value="<p>Some text</p> <a href=\'#\'>linky</a>"';

Answer 3

In this case, you can use:

$string = 'value="<p>Some text</p> <a href="#">linky</a>"';
echo substr( $string, 7, -1 ); //<p>Some texts</p> <a href="#">linky</a>

Answer 4

You cannot do this, because you don't know how which quote marks the end of the string to match and which should be included (especially when there's a variable number of quotes in the values, and more than 1 match in the string). How come are there quotes within quotes anyway? Where does this data come from?

$string = 'value="<p>Some text</p> <a href="#">linky</a>"';

Just seems very strange to me.
