Decode Field

json_decode reads JSON text so fields can be selected by name.

decode_field.php

<?php
$city = ;
$json = '{"city":"' . $city . '","state":"TX"}';
$decodedCity = json_decode($json, true)["city"];

echo "city=" . $city . "\n";
echo "decoded=" . $decodedCity . "\n";

<?php
$city = ;
$json = '{"city":"' . $city . '","state":"TX"}';
$decodedCity = json_decode($json, true)["city"];

echo "city=" . $city . "\n";
echo "decoded=" . $decodedCity . "\n";

<?php
$city = ;
$json = '{"city":"' . $city . '","state":"TX"}';
$decodedCity = json_decode($json, true)["city"];

echo "city=" . $city . "\n";
echo "decoded=" . $decodedCity . "\n";
