I have a hardware which records data in every seconds. I can connect to the hardware with a browser and use the hardware's interface and get the live data. For example: I can call the realtime data with command like this:
http://192.168.100.120:2345/realtime
That's what I can see in the browser:
DM_NumLogChans=5
DM_NumDataModes=1
DM_LogicalChan=1
DM_ChanType=SEQUENTIAL
DM_NumDims=2
DM_DataMode=1
DM_DataModeType=TIMHIS
DM_AxisLabel.Dim1=Time
DM_AxisLabel.Dim2=Value
DM_AxisUnits.Dim1=secs
DM_AxisUnits.Dim2=microstrain
DM_SampleRate=1.000000
DM_TimeBase=0.0
DM_ChanName=bridge_1
DM_UserMin=-583.220764
DM_UserMax=940.916199
DM_Start=
-439.779 -391.875 -680.114 1001.37 0
-442.068 -396.62 -680.945 1001.37 0
-443.571 -399.705 -680.639 1001.37 0
-445.598 -404.848 -684.662 1001.37 0
A new row appear in each seconds. I would like to get this data and save it to a file or display it in real time in my php program. How can I catch the data? I tried with cURL. I think that is the solution but I am really new to this. I would appreciate any help or advice you could give me.
Try this code with your url
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Set a referer
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
echo curl_download("192.168.100.120:2345/realtime");
