将字符串连接到file_put_contents

Question

I want to write both a string and an array to a file using file_put_contents in php. To write the array, I'm able to do:

file_put_contents('filename.js', json_encode(array(
    'status'    => TRUE,
    'data'      => $data
), JSON_NUMERIC_CHECK));

The resulting file then appears as:

{status:true,data:dataArray}

I would simply like to put a string before that array in the file so that it reads:

var myData = {status:true,data:dataArray}

I've tried the following unsuccessfully:

file_put_contents('all_model_data.js', json_encode("var myData =", array(
    'status'    => TRUE,
    'data'      => $data
), JSON_NUMERIC_CHECK));

And

file_put_contents('all_model_data.js', ("var myData =", json_encode(array(
    'status'    => TRUE,
    'data'      => $data
), JSON_NUMERIC_CHECK)));

Any tips? Thanks,

The first line should read:

file_put_contents('all_model_data.js', "var myData =". json_encode(array(

String concatenation in PHP is performed with the dot operator.
