Question

我想把这个字符串拆分成“Source：Web”，“Pics：1”等部分......在我的网站中使用它。从“Lat：”和“Lon：”我只需要提取数字。

    <cap>
Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555
</cap>

最好的方法是什么？我读到了关于explode（）的内容，但我没有让它发挥作用。干杯

Answer 1

以下是我使用explode（DEMO）

撰写的一些代码

<?php    
    $str = "Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555";
    $arr = explode(" | ", $str);
    foreach ($arr as $item){
        $arr2 = explode(": ", $item);
        $finalArray[$arr2[0]]=$arr2[1];
    }
    print_r($finalArray);
?>

<强> RESULT

Array
(
    [Source] => Web
    [Pics] => 1
    [Frame] => 2
    [Date] => 4-25-2011
    [On] => App
    [Lat] => 51.2222
    [Lon] => 7.6555
)

<强> USAGE

echo $finalArray['Lon']; //yields '7.6555'

Answer 2

这是一个荒谬的单行程，应该永远不会被使用，但它不使用循环（我讨厌循环）。我也喜欢练习我的REs

$str = 'Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555';
preg_match( sprintf( '~%s~', implode(array_map( function($val){ if ($val) return sprintf( '%1$s:\s(?P<%1$s>.*?)(?:(?:\s\|\s)|(?:$))', $val ); }, preg_split( '~:.*?(?:(?:\s\|\s)|(?:$))~', $str ) ) ) ), $str, $m );
print_r($m);

结果

Array
(
    [Source] => Web
    [Pics] => 1
    [Frame] => 2
    [Date] => 4-25-2011
    [On] => App
    [Lat] => 51.2222
    [Lon] => 7.6555
)

Answer 3

$pieces = explode(' | ','Source: Web...'); //Rest of string in there.
$items = array();
foreach ($pieces as $piece) {
    $parts = explode(': ', $piece);
    $items[$parts[0]] = $parts[1];
}

Answer 4

$string = "Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555";
$pieces = explode("|", $string);
print_r($pieces);

Answer 5

$items = explode(' | ', "Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555");

foreach ($items as $item) {
   $new_data = explode(': ', $item);
   $my_array[$new_data[0]] = $new_data[1];
}

print_r($my_array);

Answer 6

试试这个。它将拆分它们并创建一个关联数组：

$string = 'Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555';
$list = explode('|', $string);
$assoc = array();
foreach($list as $part) {
    list($key, $val) = explode(':', $part);
    $assoc[trim($key)] = trim($val);
}

print_r($assoc);

Answer 7

$val =<<<END
<cap>
    Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555
</cap>
END;

$bits = split("[:|]", $val);
$lat = trim($bits[11]);
$lon = trim($bits[13]);

Answer 8

你是对的。 explode是最好的功能。
