In this article, we will introduce the method to generate a
.json file in PHP.
file_put_contents() function to generate a .json file in PHP
The built-in function
file_put_contents() could write the content into a file in PHP. It searches for the file to write in, and if the desired file is not present, it creates a new file. We can use this function to create a
.json file. The correct syntax to use this function is as follows
file_get_contents($pathOfFile, $info, $customContext, $mode);
This function accepts four parameters. The detail of these parameters is as follows.
||mandatory||It specifies the path of the file.|
||mandatory||It specifies the information or data that you wish to write in a file. It can be a string.|
||optional||It is used to specify a custom context.|
||optional||It specifies the mode in which the data will be written on the file. It can be FILE_USE_INCLUDE_PATH, FILE_APPEND, and, LOCK_EX.|
This function returns the number of bytes written on the file if successful and false otherwise.
The below program will create a new
.json file and store
JSON data into it
<?php // data strored in array $array = Array ( "0" => Array ( "id" => "01", "name" => "Olivia Mason", "designation" => "System Architect" ), "1" => Array ( "id" => "02", "name" => "Jennifer Laurence", "designation" => "Senior Programmer" ), "2" => Array ( "id" => "03", "name" => "Medona Oliver", "designation" => "Office Manager" ) ); // encode array to json $json = json_encode($array); $bytes = file_put_contents("myfile.json", $json); echo "The number of bytes written are $bytes."; ?>
json_encode() function to convert the data stored in the array to a
JSON string. Once the data is converted to a
file_put_contents() function creates a
.json file and writes data into it. The output shows the number of bytes, which means the data is written successfully.
The number of bytes written is 207.
