php - 如何将此数组的字符串表示形式转换为实际的php数组

Question

这是一个例子：

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

Answer 1

这看起来像 JSON。您可以使用json_decode()它来解码它：

json_decode($array);

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); ?>
