【问题描述】：

我有这个字符串

$search_data = '{"Search Engine":"High Schools","Population":300,"Avg GPA":"3.2","Graduation Rate":"98%"}';
$data = explode(",", $search_data);
$display_data = "<br/>";
foreach($data as $item){
    $display_data .= "<span>$item</span><br/>";
}
echo $display_data;

回显的内容如下所示：

{"Search Engine":"High Schools"
"Population":300
"Avg GPA:"3.2"
"Graduation Rate":"98%"}

我怎样才能正确格式化它，使显示的文本如下所示：

Search Engine: High Schools
Population : 300
Avg GPA: 3.2
Graduation Rate: 98%

任何有用的提示将不胜感激 - 谢谢！

【解决方案1】：

由于数据是 JSON，您可以将其解码为关联数组。然后 foreach 打印每个键和值。

$search_data = '{"Search Engine":"High Schools","Population":300,"Avg GPA":"3.2","Graduation Rate":"98%"}';

foreach (json_decode($search_data, true) as $key => $value) {
    echo "$key: $value
";
}

输出

Search Engine: High Schools
Population: 300
Avg GPA: 3.2
Graduation Rate: 98%
