如何将 array_push 与关联数组和索引键一起使用？
How to use array_push with associative array and index key?
我对 php 有点“生疏”，因为有时我会使用它数周，有时您会几个月不使用。无论哪种方式，我都试图以有序的方式在另一个数组上传递另一个数组的值"array" ...我想做的基本上是创建一个键，允许我组织每行的增量值，在特别的；
数组内容
Array

[2] => 1
[3] => Inter

[8] => 5
[9] => 1
[10] => +4
[11] => 12
[12] => Chievo Verona - Inter 0 - 1
[13] => Inter - Milan 1 - 0
[14] => Carpi - Inter 1 - 2

“；”它需要能够识别你在哪里断线，我不记得是否有任何方法可以让我访问下一个键。
目前我的代码是：
$classifica = array("key" => "value");
function buildArrayClassifica()
{
global $array;
global $classifica;
$i = 0;
foreach(array_slice($array,1) as $key => $value)
{
if($value != ";")
{
array_push($classifica[$i], $value); //there is a problem
echo $value . " ";
}
else if($value == "value ")
{
continue;
}
else
{
$i++;
echo "<br/>";
}
}
}
我的代码会return这个错误：
Warning: array_push () Expects parameter 1 to be array, null given in...
特别是 array_push，它似乎不接受增量键或者我做错了。
谁能告诉我怎么解决？

如你所见，这个问题并不简单，很难解释这个问题，但我会尽量更清楚地满足你。
上面可以看到你是数组"array"的结构，但是是一个无序的结构，需要在额外的数组中排序。概括一下数组"array"的结构就是：
1 , Inter , 4 , 4 , 0 , 0 , 5 , 1 , +4 , 12 , Chievo Verona - Inter 0 - 1 , Inter - Milan 1 - 0 , Carpi - Inter 1 - 2 , Inter - Atalanta 1 - 0 , ;
“；”意味着该行已完成。所以下一个值靠近“;”意味着新的线路即将到来。我需要的是移动数组 classifica 中 "array" 的所有值，但我想将它们组织为：
ROW1 => 1 , Inter , 4 , 4 , 0 , 0 , 5 , 1 , +4 , 12 , Chievo Verona - Inter 0 - 1 , Inter - Milan 1 - 0 , Carpi - Inter 1 - 2 , Inter - Atalanta 1 - 0
ROW2 => Other values...
所以ROW1, 2 .. ra代表数组的键classifica。我试图将值推入一行并在它递增后 $i index 但是代码没有添加值，因为索引在循环中替换了实际的键，例如：
actual foreach content:
$i = 0
value = "Inter"
content of array=> [0] => Inter
now the $i is ever 0 because the row isn't finished yet, the ";"
it has not yet been reached, so the next content of foreach is:
"1" but replace the "Inter" value, so this is a problem.
您不能以这种方式使用 array_push()。请尝试：
$classifica = array();
function buildArrayClassifica()
{
global $array;
global $classifica;
$i = 0;
foreach(array_slice($array,1) as $key => $value)
{
if($value != ";")
{
$classifica[$i] = $value;
echo $value . " ";
}
else if($value == "value ")
{
continue;
}
else
{
$i++;
echo "<br/>";
}
}
}
这将在将 $value 添加到您的数组时创建索引（$i 的值）。 array_push() 会将 $value 放在下一个数字索引处，从外观上看可能不是您想要的。如果您希望索引匹配，也可以使用 $key。

经过讨论，你有一个特定的格式，其中第一个Item是Key，后面的索引是value，当你遇到value“;”时，它重新开始序列。所以当我们读到：
[2] => 1
[3] => Inter
[4] => 4
[5] => 4
[6] => 0
[7] => 0
[8] => 5
[9] => 1
[10] => +4
[11] => 12
[12] => Chievo Verona - Inter 0 - 1
[13] => Inter - Milan 1 - 0
[14] => Carpi - Inter 1 - 2
[15] => Inter - Atalanta 1 - 0
[16] => ;
第一个值'1'是我们的Index，后面的值成为这个Index的Value，找到“;”就停止阅读。这看起来像：
<?php
function buildArrayClassifica($dataArray){
$resultArray = array();
$t = array_values($dataArray);
print_r($t);
$lsc = 0;
foreach($t as $k => $v){
if((string)$v == ';'){
echo "<p>Found ';' at [$k] => {$v}</p>";
// Found end of data
// Save position
$scp = $k;
echo "<p>Recorded [$scp] position for ';'.</p>";
// Reset to find the Index, first int in this series
$c=$lsc; // First pass this should be 0
// Set the index
if($lsc ==0){
// First pass
$index = intval($t[$c]);
echo "<p>Getting Index from position [" . ($c) ."] => $index for Result Array.</p>";
$c++;
} else {
$c++;
$index = intval($t[$c]);
echo "<p>Getting Index from position [" . ($c) ."] => $index for Result Array.</p>";
$c++;
}
echo "<p>Starting to read data from [$c] until [$scp].</p>";
// Init implode variable
$data = "";
for($c;$c<$scp;$c++){
//Populate variable with the series up to semicolon, skipping first element (index)
$data .= $t[$c] . ", ";
}
echo "<p>Data collected for this round: '" . htmlentities(substr($data,0,-2)) . "'</p>";
// populate result array
$resultArray[$index] = substr($data,0,-2);
echo "<p>resultArray[$index] => " . htmlentities($resultArray[$index]) . "</p><br />";
$lsc = $scp;
}
}
return $resultArray;
}
$oldArray = array(1, "Inter", 4 , 4 , 0 , 0 , 5 , 1 , "+4" , 12 , "Chievo Verona - Inter 0 - 1", "Inter - Milan 1 - 0", "Carpi - Inter 1 - 2", "Inter - Atalanta 1 - 0", ";", 2, "Torino", 4, 3, 1, 0, 9, 4, '+5', 10, "Torino - Sampdoria 2 - 0", "Hellas Verona - Torino 2 - 2", "Torino - Fiorentina 3 - 1", "Frosinone - Torino 1 - 2", ";", 3, "apple", 0, 4, 6, "apple", ";");
$classifica = buildArrayClassifica($oldArray);
print_r($classifica);
?>
我的初步测试似乎适用于您所描述的内容。数组的第一个元素成为索引，接下来的几个值会发生内爆，直到我们到达分号 (;) 值。
我看到的结果：
Array ( [1] => Inter, 4, 4, 0, 0, 5, 1, +4, 12, Chievo Verona - Inter 0 - 1, Inter - Milan 1 - 0, Carpi - Inter 1 - 2, Inter - Atalanta 1 - 0 [2] => Torino, 4, 3, 1, 0, 9, 4, +5, 10, Torino - Sampdoria 2 - 0, Hellas Verona - Torino 2 - 2, Torino - Fiorentina 3 - 1, Frosinone - Torino 1 - 2 [3] => apple, 0, 4, 6, apple )
一边
如果是我，我会像这样将它们全部推入一个数组中：
$data = array();
for($c;$c<$scp;$c++){
$data[] = $t[$c];
}
$resultArray[$index] = $data;
或者如果你真的想要一个字符串：
$resultArray[$index] = implode(", ", $data);
希望对您有所帮助。
