JSON error if table field has dash


greatchap

Recommended Posts

Hello Everyone,

I have a PHP code that reads data from db table. Then it converts it into JSON and show it. However if data table field has - or so then it gives json error.

For e.g.

if($num > 0){
			while($res = mysqli_fetch_array($query)){
				
				$NDate = $res['NDate'];				
				$Summary = substr($res['Summary'],0,256);				
				
				/* CREATE ARRAY FOR SHORT TERM NEWSLETTER */
				$newsletters[]=array('newsletter'=>array("RecID"=>$SNo,"Summary"=>$Summary));
				
			}
			/* JSON OUTPUT*/
			$json = array("AuthOK" => 'True',"newsletters"=>$newsletters);
	
header('Content-type: application/json');
echo json_encode($json);

How to solve the issue ?

Regards,
GR

What is the JSON and what is the error?

And are you using correct character encodings? UTF-8 for the database connection and tables and columns and strings and webpages and PHP settings and I could keep going?

Sometimes output is blank and sometimes its some JSON error.

For e.g. see this text : NIFTY AS A DAY OF REST, GOES THROUGH AN INTRADAY CORRECTION, MARKETS REMAIN CHEERFUL BUY ON DIPS

If I do not change the "-" to something else the output is null/blank. My table are normal MyISAM engine MYSQL tables and field type is varchar.

Alright, that's confirmation enough for me.

You are not using UTF-8 right now. You need to be. There are a lot of places you will need to check to see what they're doing. It will take more than 5 minutes for you to fix this problem so don't rush it.

This looks like a good resource. A lot of it applies to you. Some of it does not.
