如何将array_push与关联数组和索引键一起使用？

Question

我有点'生锈与PHP,因为它发生有时我使用它几个星期有时它会发生你几个月没用.无论哪种方式,我试图传递另一个数组的值是"数组",在另一个数组上有序地...我想要做的主要是创建一个键,允许我每行组织增量值,特别是;

数组内容

Array 
(
    [key] => value
    [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] => ;
    [17] => 2
    [18] => Torino
    [19] => 4
    [20] => 3
    [21] => 1
    [22] => 0
    [23] => 9
    [24] => 4
    [25] => +5
    [26] => 10
    [27] => Torino - Sampdoria 2 - 0
    [28] => Hellas Verona - Torino 2 - 2
    [29] => Torino - Fiorentina 3 - 1
    [30] => Frosinone - Torino 1 - 2
    [31] => ;
    [32] => 3
    [33] => Fiorentina
    [34] => 4
    [35] => 3
    [36] => 0
    [37] => 1
    [38] => 5
    [39] => 3
    [40] => +2
    [41] => 9
    [42] => Carpi - Fiorentina 0 - 1
    [43] => Fiorentina - Genoa 1 - 0
    [44] => Torino - Fiorentina 3 - 1
    [45] => Fiorentina - Milan 2 - 0
    [46] => ;
    [47] => 4
    [48] => Roma
    [49] => 4
    [50] => 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允许我访问下一个键.

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/>";
        }
    }
}

代码我将返回此错误:

警告:array_push()将参数1视为数组,在...中给出null

特别是在array_push上,它似乎不接受增量键,或者我做错了.谁能告诉我怎么解决？

UPDATING

正如你所看到的那样,这个问题并不简单,很难解释这个问题,但我会尽量让自己更清楚.如上所示,您是数组"数组"的结构,但是是一个无序结构,需要在另一个数组中进行排序.概括一下数组"array"的结构是:

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 , ;

";" 该行已完成.所以接近";"的下一个值 意味着新的生产线即将到来.我需要的是移动"array"数组中的所有值classifica,但我想组织它们:

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 ..代表了数组的关键classifica.我试图将值推入一行,然后增加$ i,index但代码不会添加值,因为索引会在循环中替换实际的键,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.

Answer 1

你不能用array_push()这种方式。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/>";
        }
    }
}

当添加到数组时，这将创建索引（ 的值$i） 。会将 放置在下一个数字索引处，但从外观来看可能不是您想要的。如果您希望索引匹配，也可以使用。$valuearray_push()$value$key

编辑

经过更多讨论，您有了一个特定的格式，其中第一个 Item 是 Key，后面的索引是值，当遇到值“;”时，它会重新开始序列。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”是我们的索引，后面的值成为该索引的值，当我们找到“;”时我们停止阅读。那看起来像：

<?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情况。数组的第一个元素成为索引，接下来的几个值会内爆，直到达到分号 ( ;) 值。

我看到的结果是：

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 ) 

在旁边

如果是我，我会把它全部推入一个数组，如下所示：

$data = array();
for($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);

希望有帮助。
