PHP View the current variable type method _php instance

Below the PHP view of the current variable type background, process and solutions are written to everyone, as follows:

Resolving the background

Toss process one:

The Json_decode of JSON in PHP has not worked without any output

Period, need to understand a:

Copy the Code code as follows:
Php:curl_exec–manual

Curl_exec returns the type of variable $respjson that is not a string type.

Toss process two:

1. Search:

Copy the Code code as follows:
PHP Check Variable type

Reference:

Php:gettype–manual

Php:is_string–manual

Php:is_int–manual

So try it out:

Copy the Code code as follows:
$respJson = $crifanLib->geturlresphtml ($GETTOKENURL);
$crifanLib->logwrite ("respjson=%s", $respJson);
Echo GetType ($respJson);
echo is_string ($respJson);
echo "Before Decodedjsonobj";
$DECODEDJSONOBJ = Json_decode ($respJson);

Results:

There is still no output ...

2. Try:

Copy the Code code as follows:
Echo GetType ($respJson);
echo is_string ($respJson);

Results:

Copy the Code code as follows:
Output: String1

It proves that the type of the variable here is indeed a string.

Summarize

The variable type obtained in PHP is GetType ($var);

Individual judgments are of a certain type, which can be used:

Copy the Code code as follows:
Is_int
Is_string

Wait a minute.

The above is for PHP to view the current variable types of methods, I hope you like.
