Question

我非常抱歉，但阵列看起来像这样：

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
    )

依旧...... 当我尝试将msie6.0和msie7.0替换为InternetExplorer并将其添加时出现：

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]);

它与我想要的完美不符。任何解决方案？为了拥有：

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
    )

在您澄清评论之后。我认为你不需要正则表达式，strpos就足够了。

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