Question

任何人都可以帮忙解码这个吗？

的var_dump

../fast-export-master/hg-fast-export.sh -r "D:\MyProject"

我需要获得＆＃34;数据＆＃34;从这段代码。

Answer 1

<?php
$data='{"success":{"message":"PDF \u0444\u0430\u0439\u043b\u0430 \u0435 \u0433\u0435\u043d\u0435\u0440\u0438\u0440\u0430\u043d \u0443\u0441\u043f\u0435\u0448\u043d\u043e!","name":"invoice-0000000001.pdf","data":"JVBERi0xLjQKMSAwIG9iago8PAovVGl0bGUgKP7\/BCQEMAQ6BEIEQwRABDAAICEWADAAMAAwADAAMAAwADAAMA","type":"application\/pdf"}}';


$data=json_decode($data,true);
echo '<pre>';
print_r($data['success']['data']);

这是一个简单的json，你需要使它成为一个数组并将其作为普通数组访问。输出是您询问的数据字段：

Answer 2

嗯，你只需要<?php $input = '{"success":{"message":"PDF \u0444\u0430\u0439\u043b\u0430 \u0435 \u0433\u0435\u043d\u0435\u0440\u0438\u0440\u0430\u043d \u0443\u0441\u043f\u0435\u0448\u043d\u043e!","name":"invoice-0000000001.pdf","data":"JVBERi0xLjQKMSAwIG9iago8PAovVGl0bGUgKP7\/BCQEMAQ6BEIEQwRABDAAICEWADAAMAAwADAAMAAwADAAMA","type":"application\/pdf"}}'; $output = json_decode($input); print_r($output->success->data);那个字符串，你就得到了结果：

$args = array( 
    'parent'        => 0, 
    'hide_empty'    => 0
);
$all_cats = get_categories( $args );
echo count( $all_cats );
