Php json decode array switch statement how to#

then somehow parse out the sub arrays from $json (by doing something like referencing the addresses in array like "items.address" or "" etc (i still am not sure from the answers above how to do this.

then decode array into $json (did that).

first get the whole array eg $string (did that).

Ok so to summarize, the answers seem to indicate i have to: So this is an easy way to parse JSON with PHP.BTW, I did do var_dump, print, print_r, switch it back and forth from Object to Array, to try to learn more about array structure etc and also did a bunch of variations of echo, and for and foreach loops, etc to try to get what i wanted from array. Through this data as you would any PHP multidimensional array. This data gets converted from JSON to a PHP multidimensional array. To PHP through the json_decode() function. So, by now, you can pretty much see the trend of how you can manipulate what was originally JSON data and convert it

Running the full PHP code gives us the following output. So this finds if there is a person named Vanessa Halls and finds her city and state. Find if there is a Vanessa Halls and output her city and state If we want to see whether a person has the name "Vanessa Halls" from the JSON data and output her city and state, So now you see how you can access any element and use for loops. If I take the above PHP code and run it, I get the following output shown below. You can accessĪ particular value in an array and use the standard programming methods to extract data, such as through using for loops. For example, if your data had special (non-UTF8) characters, the jsonencode function would often return a NULL value. Then we can just handle the data as you would a multidimensional array.

The json data to a PHP multidimensional array. So, as a recap, first we must take the json data and decode it through the json_decode() function. If this is the case, we echo out all values of that person, including the name, city, and state of thatĪnd this is how we can parse JSON data with PHP. If this value is equal to Florida, then we know that So weĪccess the state of each person through the code, $people. We then want to know which of these people live in Florida. You can and should change the MySQL json format. When it gets one less than the count of the number of elements in the array, this means it has looped It counts upġ value after each iteration. Since arrays begin at element 0, this for loop starts at the value of 0. We place this value in the variable $count. We have the number of elements in the array, so that we know how many people it's composed of (we need this laterįor the for loop). We then decode this JSON data through the json_decode() function, which creates a multidimensional PHP array. So we have the same JSON data as before of people their name, city, and state. To do this we use the following PHP code below. We want to find all people who live in the state of Florida.

Let's say we are actually looking for something specific. So we can access all of the data individually that we want through the above code, but this is not really parsing through the data. Running the above PHP code, we get the following output shown below. At the time of posting this question, I didnt try searching on how to decode JSON - as thats pretty simple and I got that working. So in the above, we output all of the data of by accessing each individual data item in the multidimensional array. As per documentation for jsondecode, simply setting the second argument to true will result in the result being associative array, which can be in turn accessed like an array. We then can handle all of the data after the json_decodeįunction like a multidimensional array (which it now is). Json_decode() function is a built-in PHP function that converts JSON data into a multidimensional PHP array. So it converts the json data into something that PHP can understand through the json_decode function. PHP cannot read or handle json data, as is.

So, we first have json data stored in the variable $jsonData.
