php - 为 ExtJS 树控件准备多维数组

Question

请不要将此问题视为重复问题而关闭............ 我是 php 新手。 我正在 extjs 中开发一个树网格。我需要以树格式显示字段。所以对于前端，我需要发送编码数据。 我想要两个函数来编码和解码字符串变量、多维数组、带有一组分隔符的变量。 例如，如果我有一个数组............

array(
array( "task" => "rose",
"duration" => 1.25,
"user" => 15
),
array( "task" => "daisy",
"duration" => 0.75,
"user" => 25,
),
array( "task" => "orchid",
"duration" => 1.15,
"user" => 7
),
array( "task" => "sunflower",
"duration" => 1.50,
"user" => 70
)

);

我想将所有数组字段或单个字段编码为......

array(
array( "task" => "rose",
"duration" => 1.25,
"user" => 15
),
array( "task" => "daisy",
"duration" => 0.75,
"user" => 25$sbaa,
),
array( "task" => "orchid",
"duration" => 1.15,
"user" => 7$!ass,
),
array( "task" => "sunflower",
"duration" => 1.50,
"user" => 70$!abc
)

);

所以像这样我只需要编码字符串，带有分隔符的变量......... 稍后，所有编码值在返回后端之前都将被解码......为此，我必须使用这个插件............ 编码.class.php......................

Answer 1

为什么不使用 json_encode？就这么做

$str=json_encode($array);

然后，发送数据，另一端做

$array=json_decode($str);
