php数组迭代&连接 [英] php array iteration & concatenate

问题描述

我有一个看起来像下面的数组，我想检查下一个elem是否以空格开头，如果是，则将其连接到前一个elem。

I have an array that looks like the one below, I would like to check if the next elem starts with a space, if it does, concatenate it to the previous elem.

[1] => Array (
    [1] => lenny/volatile/main Packages
    [2] => lenny/volatile/main Packages
    [3] => lenny/volatile/main Sources
    [4] =>  Reading package
    [5] => lenny/volatile/main Sources
)

Output:

[1] => Array (
    [1] => lenny/volatile/main Packages
    [2] => lenny/volatile/main Packages
    [3] => lenny/volatile/main Sources Reading package
    [5] => lenny/volatile/main Sources
)

谢谢！

推荐答案

$count = count($array);
for($i = 0; $i < $count; $i++){
    if($array[$i][0] == ' '){
        if($i > 0){
             $array[$i-1] .= $array[$i];
             unset($array[$i])
        }
    }
}

应该这样做（也就是说，如果您的数组名为 $ array ，否则适合您的需要）

That should do it (that is if your array is named $array, otherwise suit it to your needs)
