Answer 1

看起来像是JSON。你可以使用json_decode()进行解码：

json_decode($array);

- rid

Answer 2

使用此代码将此字符串转换为数组。

    <?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); ?>
