I am using s3cmd to get files from AWS to my ubuntu server.
s3cmd get s3://bucket/filename newfilename
It works fine when run from terminal of ubuntu.
But when I run from php like below
$query1 = 's3cmd get s3://bucket/filename newfilename';
$q1 = serialize(shell_exec($query1));
$data2 = array( 'data' => $q1);
header('Content-type: application/json');
echo json_encode( $data2 );
It works but response from json_encode it concatenated with extra text.
{"data":"s:122:\"File s3:............
What is s:122 and how to remove this. I am not looking for sub_string though.
When you serialize
some value - in a result string there's type of value and value itself. s:122
, you asked about, says that values is a string with length 122
. So if you don't want this string appear - don't serialize value.
