Can we call an variable and function directly when we include an file in php -

-



dbc.php

<?php  $con = mysqli_connect("****", "****", "****", "employees"); if(!$con) {   echo "connection error";   die(); }  ?>

index.php

<?php require("dbc.php");  $query = mysqli_query($con, "select * uname"); //error : undefined $con if(!$query) {   echo "query error";   die(); } ?>

how can call variables , functions when include file. why above declared $con showing error?

python - Read npy file directly from S3 StreamingBody -

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
