PHP - 正則表達式匹配成才與

Question

很對不起啓動，但該陣列是這樣的：

Array 
(
[1] => Array 
    (
     [0] => msie6.0 
     [1] => 7 
    ) 

[2] => Array 
    (
     [0] => safari5.0.3 
     [1] => 5 
    ) 

[3] => Array 
    (
     [0] => chrome18.0.1025.308 
     [1] => 1 
    ) 

[4] => Array 
    (
     [0] => firefox20.0 
     [1] => 4 
    ) 
[5] => Array 
    (
     [0] => msie7.0 
     [1] => 915 
    ) 

等等... 當我試圖取代例如msie6.0和msie7.0與InternetExplorer並添加它：

preg_match("/#^msie(.*)$#i/is", $results, $matches); 
$test = $matches[0] ; 
print_array($test); 
$results["#^startText(.*)$#i"] = $results['InternetExplorer']; 
print_array($results); 
unset($results["/#^msie(.*)$#i/is]); 

它不符合我想要的完美。任何解決方案？ 爲了有：

Array 
(
[1] => Array 
    (
     [0] => InternetExplorer 
     [1] => 922 
    ) 

[2] => Array 
    (
     [0] => safari5.0.3 
     [1] => 5 
    ) 

[3] => Array 
    (
     [0] => chrome18.0.1025.308 
     [1] => 1 
    ) 

[4] => Array 
    (
     [0] => firefox20.0 
     [1] => 4 
    )

在澄清您的意見後。我認爲你不需要正則表達式，strpos就足夠了。

$rows["InternetExplorer"] = 0; 
foreach($rows as $key => $value){ 
    if(strpos($key,"msie") !== false){ 
    $rows["InternetExplorer"] += $value; 
    unset($rows[$key]); 
    } 
}
