Problems with PHP Curl receiving data

The receiving end is Print_r ($_post);

The sending side writes a curl to submit the post.

$ch = Curl_init (); Curl_setopt_array ($ch, array (curlopt_url = ' http://myurl/abc.php ', Curlopt_returntransfer = True,curlopt_post = True,curlopt_postfields = ' name=abc&id=123 '); $content = curl_exec ($ch);p Rint_r ($ content); Echo '
=========
'; Echo $content [' name '];

Print out the results:

Array (    [name] = + ABC    [id] = 123) =========a

Why $content[' name ' gets a letter a ...

$content = curl_exec ($ch);

This line of code gets the $content is a string. So you print this string when you echo.
Change the Print_r to Var_dump.

Var_dump ($content);

Get results:

String "Array (    [name] + ABC    [id] = 123)"

echo $content [' name ']; This sentence

$content is a string where ' name ' is being multiplied by the integer 0, so it is the first letter A.
