cyberRobot Posted April 30, 2020 Share Posted April 30, 2020 The following line looks like JSON. {"code":0, "reason":"OK", "resp":"AT+CCFC=1,3,\" 92061460\"\r\nERROR\r\n"} You could try using PHP's json_decode() function to extract the code, reason, and resp variables. More information, including examples, can be found in the manual.https://www.php.net/manual/en/function.json-decode.php Then you could use explode() to break the "resp" component based off the double quote ("). Then chop off the third value, assuming the lines always look similar to the above. Does the following line come from the API? {"code": 0, "reason": "OK", "resp": "AT + CCFC = 1,3, \" 92061460 \ "\ r \ nOK \ r \ n"} Unless I'm missing something, that's not valid code. Basically, the "resp" portion is equal to "AT + CCFC = 1,3, \" 92061460 \ "\ r \ nOK \ r \ n", which is surrounded by double quotes. In order to use double quotes in the middle of the string, they need to be escaped with a backslash. The first escaped quote is fine. The second one is not since there is a space between the backslash and the quote. The \r and \n entities are also invalid because of the extra spaces.
