如何将数组的字符串表示形式转换为实际的php数组

Question

以下是一个例子：

$array = "[[51.228697283276,0.45897198252166],[51.228697283276,0.59374016480853],[51.312903819352,0.59374016480853],[51.312903819352,0.45897198252166]]";

Answer 1

看起来像JSON。您可以使用json_decode()对其进行解码：

json_decode($array);

Answer 2

使用此代码将此字符串设为数组

    <?php 
$string ="[[51.228697283276,0.45897198252166],[51.228697283276,0.59374016480853],[51.312903819352,0.59374016480853],[51.312903819352,0.45897198252166]]";
$array = explode(',',$string);
for($i=0;$i<count($array);$i++){
    $array[$i] = trim($array[$i],'[[');
    $array[$i] = trim($array[$i],']]');
}
echo '<pre>'; print_r($array); ?>
