In the final step, the json_encode() function converts the associative array and writes it into an output JSON file.JSON stands for 'JavaScript Object Notation' and is pronounced 'Jason' (like in the Friday the 13th movies). This loop prepares an associative array containing the CSV data. On each iteration, it associates the header column and the iterated data column. Then, the code iterates the CSV rows from the second row onwards. It creates the header column array by getting the first row of the CSV file.

This example uses a CSV string as its input instead of a file. Method 2: Convert CSV (containing header) into a JSON (associating the column=>value pair) Method 3: Upload a CSV file and convert it into JSON.Method 2: Convert CSV (containing header) into a JSON (associating the column=>value pair).

In the following sections, we will see two more examples of converting CSV files into JSON. This PHP quick example displays the below JSON output on the browser. The below input file is saved and used for this PHP example.

When we saw the methods of reading a CSV file, we created an example using str_getcsv function. This line maps the array to call PHP str_getcsv to parse and convert the CSV lines into an array. In step 3, the iteration happens with a single line of code.

Finally, the resultant CSV row array is converted to JSON using the json_encode() function.

Then, it iterates the line array and reads the line data of the CSV row.

It explodes the CSV row by the new line ( ) escape sequence.

csv file content using the PHP file_get_contents() function. The above quick example in PHP converts the CSV file content into JSON with few lines of code. In this article, we will see different methods of achieving this conversion. Most of the existing API responses are in JSON format.Ĭonverting CSV content into a JSON format is simple in PHP. JSON format is a widely used format while working with API development.
