json_false()는 false를 반환합니다.

json_false()는 false를 반환합니다.

boolean 값의 var_dumping json_encode는 이번이 처음입니다.

직렬화 해제된 어레이가 있습니다.var_dump하여 유효한 어레이임을 확인했습니다.결과는 다음과 같습니다.이것은 디버깅 뷰 전체가 아니라 일부분에 불과합니다.

그 후 최대 깊이=3으로 처리한다.주의: 저는 PHP 5.5를 사용하고 Apache 2.4에서 실행 중이기 때문에 json_encode()에서 depth 파라미터를 지원합니다.이게 내가 하고 있던 일이야.

    $array = unserialize($serial);
    var_dump($array);
    $json = json_encode($array, JSON_PRETTY_PRINT, 3);
    var_dump($json);

마침내 나는 얻었다.$arrayvar_interface를 적절히 설정해 주세요.$jsonvar_false 부울값의 결과입니다.무슨 문제라도 있습니까?초기 PHP 릴리스 때문에 var_dump가 잘못되어 부울이 잘못되었습니까?누가 이런 상황을 겪어본 적 있나요?

갱신:

이것은 시리얼라이즈 문자열입니다.줄이 너무 많아서 한 조각만 붙여요.

심도$array확실히 3보다 큽니다.깊이를 더 크게 해 주세요.

참고로 json_encode에 장애가 발생했을 경우 를 사용하여 에러 메시지를 표시할 수도 있습니다.

이 기능은 php.net에서 이미 제안하고 있는 기능을 사용해 보십시오.

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;   
}
