There are two functions when querying a php database.
Oci_fetch_object and oci_fetch_array () return the return values of the object and array types respectively. now I need a string type. how can I convert it?


$ Results = "[";
$ Row = oci_fetch_array ($ stmt); <-oci_fetch_object can be used here.
$ Results + = ??? <-Here, if you convert the returned value $ row to the string type, I have tried (string ).
$ Results = "]";

------ Best solution --------------------
While ($ row = oci_fetch_array ($ stmt )){
$ Result [] = $ row;
}
$ Result = json_encode ($ result );
------ Other solutions --------------------
What you may need is json_encode.

I tried it. no...
In fact, my goal is to convert the returned values of oci queries into json strings.
------ Other solutions --------------------
According to your format, you want to convert the object or array to the json format ..
Upstairs positive solution, convert to json is json_encode, convert json to array is json_decode
If you want to splice it yourself, you can also. The array is converted to string, and implode is used directly.

$ Results = "[";
$ Usercount = 0;
$ Row = oci_fetch_array ($ stmt );
If ($ row ){
$ Results + = $ row;
$ Usercount ++;
}
While (1 ){
$ Row = oci_fetch_array ($ stmt );
If (! $ Row) break;

$ Results + = "," + $ row;
$ Usercount ++;
}
$ Results + = "]";

This is my code, and the resulting $ results is 0 instead of a json Array. the query contains multiple returned values.
------ Other solutions --------------------
Reference:

While ($ row = oci_fetch_array ($ stmt )){
$ Result [] = $ row;
}
$ Result = json_encode ($ result );

After this change, the system prompts Cannot use a scalar value as an array in, and then $ result = ""
------ Other solutions --------------------
You deleted your original $ results =!

Deleted, write only
While ($ row = oci_fetch_array ($ stmt )){
$ Result [] = $ row;
}
$ Result = json_encode ($ result );
And then return $ result.

$ Result [] = $ row; prompt Cannot use a scalar value as an array in

Yes. I just found that there is a $ result definition at the beginning of the function. just delete it.
