如何循环打印每个 CUSTNAME？

【问题讨论】：

json decode in php的可能重复

标签： php json parsing

【解决方案1】：

一旦你有 json_decode 结果返回一个正确的关联数组

$myJson = json_decode($json, true);

你有一个可以迭代数组的元素数组，例如：使用 echo 显示值

foreach ($myJson as $key => $value){
      echo $value['CUSTNAME'] . '<br>';
}

如果想使用 for 循环

$cnt = count($myJson);

for ($i = 0; $i<$cnt; $i++){
    echo $myJson[$i]['CUSTNAME'] . '<br>';
}

【解决方案2】：

您可以json_decodejson 并使用array_column 方法获取每个CUSTNAME 键值。

$json = '[{"CUSTOMERCODE":"9879","CUSTNAME":"ASHIQUE","MOBILE":"","NATION":"INDIA","AREA":"AL QUOZ"},{"CUSTOMERCODE":"5678","CUSTNAME":"SALIH","MOBILE":"971528381946","NATION":"UAE","AREA":"DEIRA"},{"CUSTOMERCODE":"2345","CUSTNAME":"HABEEB","MOBILE":"12345678","NATION":"SAUDI","AREA":"AL QOUZ 4"},{"CUSTOMERCODE":"5433","CUSTNAME":"AZHAR","MOBILE":"12345678","NATION":"USA","AREA":"AL QOUZ 3"},{"CUSTOMERCODE":"5698","CUSTNAME":"BAIJU","MOBILE":"12345678","NATION":"UK","AREA":"AL KHAIL"},{"CUSTOMERCODE":"3854","CUSTNAME":"RAHUL","MOBILE":"12345678","NATION":"KUWAIT","AREA":"AL QUOZ"},{"CUSTOMERCODE":"5623","CUSTNAME":"LINESH","MOBILE":"12345678","NATION":"UAE","AREA":"AL KHAIL"},{"CUSTOMERCODE":"9879","CUSTNAME":"ASHIQUE","MOBILE":"12345678","NATION":"INDIA","AREA":"AL QUOZ"},{"CUSTOMERCODE":"5678","CUSTNAME":"SALIH","MOBILE":"12345678","NATION":"UAE","AREA":"DEIRA"},{"CUSTOMERCODE":"2345","CUSTNAME":"HABEEB","MOBILE":"12345678","NATION":"SAUDI","AREA":"AL QOUZ 4"},{"CUSTOMERCODE":"5433","CUSTNAME":"AZHAR","MOBILE":"12345678","NATION":"USA","AREA":"AL QOUZ 3"},{"CUSTOMERCODE":"5698","CUSTNAME":"BAIJU","MOBILE":"12345678","NATION":"UK","AREA":"AL KHAIL"},{"CUSTOMERCODE":"3854","CUSTNAME":"RAHUL","MOBILE":"971557557863","NATION":"KUWAIT","AREA":"AL QUOZ"},{"CUSTOMERCODE":"5623","CUSTNAME":"LINESH","MOBILE":"12345678","NATION":"UAE","AREA":"AL KHAIL"}]';

$data = json_decode($json);
echo "<pre>";
print_r(array_column($data, 'CUSTNAME'));
