如何在PHP中格式化動態生成的嵌套數組

Question

我試圖通過使用Pods Framework從數據庫中提取多邊形數據來動態生成嵌套數組，但是我正在努力使格式/語法正確（當涉及PHP時，我不是專家）。

這是我的代碼，其中“ polygon_latlon”是包含雙引號內的緯度和經度點對的字段，雙引號之間用逗號分隔（組成（不規則）多邊形）：

$lines = array();

//set find parameters
$params = array(
    'limit' => -1
);
//get pods object
 $maps = pods( 'maps_osexplorer', $params );
//loop through records
 if ( $maps->total() > 0 ) {
 while ( $maps->fetch() ) {

 $polygon1 = $maps->field('polygon_latlon');

 $lines[] = "array($polygon1)";

}

}

 $polygons1 = implode(',', $lines);

使用以下格式的print_r（$ lines）輸出：

即我需要嵌套在另一個數組中的print_r（$ polygons1）的輸出。 我將如何實現？

最終，我不想打印嵌套的數組，而是將其存儲為變量以供另一段代碼使用。

Answer 1

抱歉，我來晚了，但是您可以使用以下代碼來實現，

$var = array($polygons1)
