php - 正则表达式以匹配以...开头的内容

问题描述：

I am terribly sorry but the array looks like this:

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
    )

and so on... When i try to replace for example msie6.0and msie7.0 with InternetExplorer and add it occurence :

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]);

it not match the perfect as i want. any solution for that ? in order to have :

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
    )

我非常抱歉，但数组看起来像这样： p>

 数组
（
 [1] =＆gt;数组
（
 [0] =＆gt; msie6.0 
 [1] =＆gt; 7 
）
 
 [2] =＆gt; 数组
（
 [0] =＆gt; safari5.0.3 
 [1] =＆gt; 5 
）
 
 [3] =＆gt;数组
（
 [0] =＆gt; chrome18  .0.1025.308 
 [1] =＆gt; 1 
）
 
 [4] =＆gt;数组
（
 [0] =＆gt; firefox20.0 
 [1] =＆gt; 4  
）
 [5] =＆gt;数组
（
 [0] =＆gt; msie7.0 
 [1] =＆gt; 915 
）
  code>  pre> 
  
 依此类推... 
当我尝试用 InternetExplorer  code>替换示例 msie6.0  code>和 msie7.0  code>时 添加它出现： p> 
 
 
  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]);

nn不匹配 他完美如我所愿。 任何解决方案？
为了拥有： p> 
 
 
 数组
（
 [1] =＆gt;数组
（
 [0] =＆gt; InternetExplorer  
 [1] =＆gt; 922 
）
 
 [2] =＆gt;数组
（
 [0] =＆gt; safari5.0.3 
 [1] =＆gt; 5 
）\  n 
 [3] =＆gt;数组
（
 [0] =＆gt; chrome18.0.1025.308 
 [1] =＆gt; 1 
）
 
 [4] =＆gt;数组\  n（
 [0] =＆gt; firefox20.0 
 [1] =＆gt; 4 
）
  code>  pre> 
  div>

答

After your clarification in comment. I think you don't need regex, strpos is enough too that job.

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

DEMO.
