json在php中的使用之如何转换json为数组
<?php $json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; var_dump(json_decode($json)); echo"<br/>"; var_dump(json_decode($json, true)); ?> 数组$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';被json_decode()解码，转换回来的数据是对象，var_dump(json_decode($json))得到的是一个对象，如下： 1 object(stdClass)#1 (5) { [ "a" ]=> int(1) [ "b" ]=> int(2) [ "c" ]=> int(3) [ "d" ]=> int(4) [ "e" ]=> int(5) } 那么，要怎么样才能把json数组转换为php格式的数组呢，采用以下方式： json_decode($json, true) 1 var_dump(json_decode( $json , true)); 效果如下： array(5) { ["a"]=> int(1) ["b"]=> int(2) ["c"]=> int(3) ["d"]=> int(4) ["e"]=> int(5) } <?php $json = '{"a":1,"b":2,"c":3,"d":4,"e
