foreach循环问题

I made this code :

$matches = array();
preg_match_all('/"Type":".+?",/', $text, $matches);


foreach($matches[0] as $match) {
    if (isset($_GET['dvd']) && !empty($_GET['dvd'])) {
        $dvd = $_GET['dvd'];
        if (stripos($match, 'DVD') !== false) {
            $match = '';
        }
    }
    echo $match;
}

In this code i search for the word "type" in $text and it stores the whole line with the words ahead of it in the array. And then i loop through each one and see if the word DVD is there. If it is then, it removes it and displays a blank line.

Now I also want to search for suppose manufacturer and display it beneath every type returned.

So it should return suppose the result :

Type: HDD
Manufacturer: WD

Type: Flash Drive
Manufacturer: Transcend

Type: CD
Manufacturer: Sony

So I tried it with putting another preg_match_all expression:

$anotherMatch = array();
preg_match_all('/"Manufacturer":".+?",/', $text, $anotherMatch);

And I tried combining this with the previous foreach expression with an && operator but it didn't work. Also I tried different foreach expressions and then one for echoing at the end. but that also didn't work.

Can you tell me how to achieve the desired result. Thanks...

Given source input like this:

"Type":"HDD",
"Manufacturer":"WD",
"Other":"Nonsense",
"Type":"Flash Drive",
"Manufacturer":"Transcend",
"Other":"More nonsense",
"Type":"CD",
"Manufacturer":"Sony",
"Other":"Yet even more nonsense",

And expecting output like this:

Type: HDD
Manufacturer: WD

Type: Flash Drive
Manufacturer: Transcend

Type: CD
Manufacturer: Sony

You could use this regular expression:

/"(Type|Manufacturer)":"([^"]+?)",/

And loop over it like this:

preg_match_all('/"(Type|Manufacturer)":"([^"]+?)",/', $text, $matches);

foreach($matches[0] as $match => $line)
{
    if (!empty($_GET['dvd']) && stripos($matches[2], 'DVD') !== false)
    {
        continue;
    }
    echo $matches[1][$match] . ': ' . $matches[2][$match] . "
";
}

Although, I don't think that will do quite exactly what you want it to.
