How to convert php array to json format, php array json format

The example in this article describes the method of converting php array to json format. Share it with everyone for your reference. The specific implementation method is as follows:

Copy code The code is as follows: function array_to_json( $array ){
If( !is_array( $array ) ){
         return false;
}
$associative = count( array_diff( array_keys($array), array_keys( array_keys( $array )) ));
If( $associative ){
​​​​ $construct = array();
foreach( $array as $key => $value ){
// We first copy each key/value pair into a staging array,
// formatting each key and value properly as we go.
                         // Format the key:
If( is_numeric($key) ){
                   $key = "key_$key";
            }
              $key = "'".addslashes($key)."'";
                         // Format the value:
                 if( is_array( $value )){
                     $value = array_to_json( $value );
                  } else if( !is_numeric( $value ) || is_string( $value ) ){
                  $value = "'".addslashes($value)."'";
            }
// Add to staging array:
               $construct[] = "$key: $value";
}
// Then we collapse the staging array into the JSON form:
$result = "{ " . implode( ", ", $construct ) . " }";
} else { // If the array is a vector (not associative):
​​​​ $construct = array();
foreach( $array as $value ){
                         // Format the value:
                 if( is_array( $value )){
                     $value = array_to_json( $value );
                 } else if( !is_numeric( $value ) || is_string( $value ) ){
                   $value = "'".addslashes($value)."'";
            }
// Add to staging array:
                $construct[] = $value;
}
// Then we collapse the staging array into the JSON form:
          $result = "[ " . implode( ", ", $construct ) . " ]";
}
Return $result;
}
