Question

我正在将一种颜色推入一个数组，用一种颜色覆盖每个条形图颜色，但它没有按预期工作，这些数组有问题。

我的原始问题：如何在pChart中将数组推送到barChart并使用单色进行颜色覆盖？

更新问题：print_r结果显示额外的2组数组，它应该只是一个包含数组的数组，没有更深，这些数据会被添加到哪里？我该如何纠正？

PHP / pChart：

$prop_open=(1,5,8,4,2,66);

$j=0;
$palette_cycle=array();
foreach($prop_open as $value) {
    array_push($palette_cycle,array("$j"=>array("R"=>108,"G"=>157,"B"=>49,"Alpha"=>100)));
    $j++;
}

$palette=$palette_cycle;
$myPicture->drawBarChart(array("OverrideColors"=>$palette,"DisplayOrientation"=>ORIENTATION_HORIZONTAL,"DisplayPos"=>LABEL_POS_INSIDE,"DisplayValues"=>TRUE,"DisplayColor"=>DISPLAY_MANUAL,"DisplayR"=>0,"DisplayG"=>0,"DisplayB"=>0,"Surrounding"=>-60,"InnerSurrounding"=>60));

这就是我的$ palette_cycle数组应该在完成之后的结果（但所有RGB都是相同的）：

$palette_cycle = array("0"=>array("R"=>188,"G"=>224,"B"=>46,"Alpha"=>100),
                 "1"=>array("R"=>224,"G"=>100,"B"=>46,"Alpha"=>100),
                 "2"=>array("R"=>224,"G"=>214,"B"=>46,"Alpha"=>100),
                 "3"=>array("R"=>46,"G"=>151,"B"=>224,"Alpha"=>100),
                 "4"=>array("R"=>176,"G"=>46,"B"=>224,"Alpha"=>100),
                 "5"=>array("R"=>224,"G"=>46,"B"=>117,"Alpha"=>100),
                 "6"=>array("R"=>92,"G"=>224,"B"=>46,"Alpha"=>100),
                 "7"=>array("R"=>224,"G"=>176,"B"=>46,"Alpha"=>100));

$ palette_cycle的打印结果：

Array ( 
[0] => Array ( [0] => Array ( [R] => 108 [G] => 157 [B] => 49 [Alpha] => 100 ) ) 
[1] => Array ( [1] => Array ( [R] => 108 [G] => 157 [B] => 49 [Alpha] => 100 ) ) 
[2] => Array ( [2] => Array ( [R] => 108 [G] => 157 [B] => 49 [Alpha] => 100 ) ) 
[3] => Array ( [3] => Array ( [R] => 108 [G] => 157 [B] => 49 [Alpha] => 100 ) ) 
[4] => Array ( [4] => Array ( [R] => 108 [G] => 157 [B] => 49 [Alpha] => 100 ) ) 
[5] => Array ( [5] => Array ( [R] => 108 [G] => 157 [B] => 49 [Alpha] => 100 ) ) )

Answer 1

也许尝试使用这样的数组：

$j=0;
$palette_cycle=array();
foreach($prop_open as $value) {
   $palette_cycle[] = array("R"=>108,"G"=>157,"B"=>49,"Alpha"=>100);
}

1，使用整数索引而不是字符串索引 2，不需要array_push

Answer 2

试试这个

foreach($prop_open as $value) {
array_push($palette_cycle,"$j"=>array("R"=>108,"G"=>157,"B"=>49,"Alpha"=>100));
$j++;
}

如果没有，请尝试

foreach($prop_open as $value) {
$palette_cycle[$j] = array("R"=>108,"G"=>157,"B"=>49,"Alpha"=>100);
$j++;
}

如何纠正foreach循环并获得所需的数组深度？
