如何prePEND阵列与我的选择键和值（PHP）另一个数组中的每个元素？ [英] How to prepend array to each element of another array with my choice of key and value (in php)?
本文介绍了如何prePEND阵列与我的选择键和值（PHP）另一个数组中的每个元素？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这code：
为（$ P = 0; $ P＆LT;计数（$结果）; $ P ++）{
的foreach（$结果[$ P]为$ K =＆GT; $ V）{
$ typeee = ['型'=＆GT;用strtolower（str_replace函数（'_'，''，$结果[$ P] [$ k]的['指标']））集装箱]。
array_insert2（$结果[$ P]，0，$ typeee）;
}
}
的print_r（$结果）;
给我这样的：
阵列（
[0] =＆GT;排列
（
[类型] = GT; pagestoriescontainer
[0] =＆GT;排列
（
[类型] = GT; pagestories
[OBJECT_ID] =＆GT; 123456778
[指标] =＆GT; page_stories
[END_TIME] =＆GT; 1386057600
[期] =＆GT; 86400
[值] =＆GT; 2090
） [1] =＆GT;排列
（
[类型] = GT; pagestorytellers
[OBJECT_ID] =＆GT; 123456778
[指标] =＆GT; page_storytellers
[END_TIME] =＆GT; 1386057600
[期] =＆GT; 86400
[值] =＆GT; 2041
）
[...][1] =＆GT;排列
（ [0] =＆GT;排列
（
[类型] = GT; pagestories
[OBJECT_ID] =＆GT; 199193463123456778
[指标] =＆GT; page_stories
[END_TIME] =＆GT; 1386057600
[期] =＆GT; 86400
[值] =＆GT; 0
） [1] =＆GT;排列
（
[类型] = GT; pagestorytellers
[OBJECT_ID] =＆GT; 199193463123456778
[指标] =＆GT; page_storytellers
[END_TIME] =＆GT; 1386057600
[期] =＆GT; 86400
[值] =＆GT; 0
） [...]
但是，这code：
为（$ P = 0; $ P＆LT;计数（$结果）; $ P ++）{
的foreach（$结果[$ P]为$ K =＆GT; $ V）{
$ typeee = ['型'=＆GT;用strtolower（str_replace函数（'_'，''，$结果[$ P] [$ k]的['指标']））集装箱]。
array_insert2（$结果[$ P]，$ K，$ typeee）;
}
}
不给我这样的：
阵列（
[0] =＆GT;排列
（
[类型] = GT; pagestoriescontainer
[0] =＆GT;排列
（
[类型] = GT; pagestories
[OBJECT_ID] =＆GT; 123456778
[指标] =＆GT; page_stories
[END_TIME] =＆GT; 1386057600
[期] =＆GT; 86400
[值] =＆GT; 2090
）
[类型] = GT; pagestorytellerscontainer
[1] =＆GT;排列
（
[类型] = GT; pagestorytellers
[OBJECT_ID] =＆GT; 123456778
[指标] =＆GT; page_storytellers
[END_TIME] =＆GT; 1386057600
[期] =＆GT; 86400
[值] =＆GT; 2041
）
[...][1] =＆GT;排列
（
[类型] = GT; pagestoriescontainer
[0] =＆GT;排列
（

为什么呢？我怎样才能得到我想要什么？ ：）
此外，
函数array_insert2（安培; $数组$地位，$ insert_array）{
$ first_array = array_splice（$数组，0，$位置）;
$阵列= array_merge（$ first_array，$ insert_array，$阵列）;
}
解决方案
array_insert2的第二个参数是位置。在第一个code你实际上是给它一个整数使它成为一个有效的位置（$ P，与array_splice功能相结合）。
在第二片$ C $的c，提供到array_insert2位置是从$结果[$ P] foreach循环密钥（$ K）。给出的键不能用array_splice功能正确使用。也许的供应，而不是$ K，给出$ K的$结果array_search结果[$ P]。
简答：
在第二片$ C $的c供给的位置不是一个整数，使得它不可用于所述array_splice功能
This code :
for ($p=0;$p<count($results);$p++){
foreach ($results[$p] as $k => $v){
$typeee = ['type' => strtolower(str_replace('_','',$results[$p][$k]['metric']))."container"];
array_insert2($results[$p],0,$typeee);
}
}
print_r($results);
gives me this:
Array (
[0] => Array
(
[type] => pagestoriescontainer
[0] => Array
(
[type] => pagestories
[object_id] => 123456778
[metric] => page_stories
[end_time] => 1386057600
[period] => 86400
[value] => 2090
)
[1] => Array
(
[type] => pagestorytellers
[object_id] => 123456778
[metric] => page_storytellers
[end_time] => 1386057600
[period] => 86400
[value] => 2041
)
[...]
[1] => Array

[0] => Array

[type] => pagestories
[object_id] => 199193463123456778
[metric] => page_stories
[end_time] => 1386057600
[period] => 86400
[value] => 0
)
[1] => Array

[metric] => page_storytellers
[end_time] => 1386057600
[period] => 86400
[value] => 0
)
[...]
But this code:
for ($p=0;$p<count($results);$p++){
foreach ($results[$p] as $k => $v){
$typeee = ['type' => strtolower(str_replace('_','',$results[$p][$k]['metric']))."container"];
array_insert2($results[$p],$k,$typeee);
}
}
DOES NOT give me this:
Array (
[0] => Array
(
[type] => pagestoriescontainer
[0] => Array
(
[type] => pagestories
[object_id] => 123456778
[metric] => page_stories
[end_time] => 1386057600
[period] => 86400
[value] => 2090
)
[type] => pagestorytellerscontainer
[1] => Array

[type] => pagestorytellers
[object_id] => 123456778
[metric] => page_storytellers
[end_time] => 1386057600
[period] => 86400
[value] => 2041
)
[...]
[1] => Array
(
[type] => pagestoriescontainer
[0] => Array
(
[type] => pagestories
[object_id] => 199193463123456778
[metric] => page_stories
[end_time] => 1386057600
[period] => 86400

[end_time] => 1386057600
[period] => 86400
[value] => 0
)
[...]
Why? How can I get what I want? :)
Also,
function array_insert2 (&$array, $position, $insert_array) {
$first_array = array_splice ($array, 0, $position);
$array = array_merge ($first_array, $insert_array, $array);
}
解决方案
array_insert2's second param is the position. In the first code you are actually giving it an integer making it a valid position ( $p, combined with the array_splice function ). In the second piece of code, the position supplied to array_insert2 is the key ( $k ) from the foreach loop on $results[$p]. The key given cannot be used correctly with the array_splice function. Maybe instead of supplying $k, give the array_search result of $k in $results[$p].
short-answer: The position supplied in the second piece of code is not an integer, making it not usable for the array_splice function.
