[英]PHP function for concating matching index strings in array?
Alright, I know it can be done like so... 好吧,我知道可以这样做......
$Array1 = array("Hello, ", "foo", "The quick brown fox jumped ");
$Array2 = array("World!", "bar", "the lazy dog.");
$Array3 = array();
for($x = 0; $x < count($Array1); $x++) {
$Array3[] = $Array1[$x] . $Array2[$x];
}
// returns this -> ("Hello, World", "foobar", "The quick brown fox jumped over the lazy dog.")
But is there a native PHP function for this? 但是有一个原生的PHP函数吗? Like this:
像这样:
$Array3 = array_concat_strings($Array1, $Array2)
I searched through php.net, and didn't find anything, but I like to be sure I'm not missing something. 我通过php.net搜索,但没有找到任何东西,但我想确定我没有遗漏任何东西。
我不认为有这样一个特殊的本机功能,但你可以自己做:
$array3 = array_map(function ($a, $b) { return $a . $b; }, $array1, $array2);
对不起,没有这样的功能
There is no such native function, but you can do it without the third array, for example 没有这样的本机功能,但是你可以在没有第三个数组的情况下完成它
foreach($Array1 as $key=>$value)
$Array1[$key] .= $Array2[$key];
print_r($Array1);
