Question

我正在尝试使用php脚本将内容附加到json文件。

file1的输出是

[
{"id":"drives","name":"hddcntrlr"},
{"id":"drives","name":"diskdrivedes"}
]

file2的输出是

[
{"id":"filters","name":"filter_supptype_cp_01"},
{"id":"drives","name":"hddcntrlr"},
{"id":"drives","name":"diskdrivedes"}
]

附加输出后

应为：

[
{"id":"filters","name":"filter_supptype_cp_01"}]
[{"id":"drives","name":"hddcntrlr"},
{"id":"drives","name":"diskdrivedes"}
]

但输出结果如下： -

$file = file_get_contents('makejson.json');
$data = json_decode($file);
$info[] = array('id'=>$attribute1, 'name'=>$sub_attr_name);
$newb = array_values((array)$info);
file_put_contents('makejson.json',json_encode($newb),FILE_APPEND);

我尝试的代码是：

<?php
phpinfo();

请帮助!!!!

Answer 1

解码两个文件，追加数组，再次编码：

$existingData = json_decode(file_get_contents('file1.json'));
$newData = json_decode(file_get_contents('file2.json'));

$existingData = array_merge($existingData, $newData);
file_put_contents('file1.json', json_encode($existingData));

Answer 2

array_push（）函数将一个或多个元素插入到数组的末尾。

您的代码：

$file = file_get_contents('makejson.json');
$tempArray = json_decode($file);
array_push($tempArray, $data); // $data is your new data
$jsonData = json_encode($tempArray);
file_put_contents('makejson.json', $jsonData);

您不需要BB1_MODULES = { 'BB103': Module('BB103', 'Computer Systems', 5), 'BB111': Module('BB111', 'Web Design', 5), 'BB112': Module('BB112', 'Digital Innovation', 5), 'BB123': Module('BB123', 'Computer Programming I', 10), 'BB124': Module('BB124', 'Computer Programming II', 10), 'BB343': Module('BB343', 'Networks and Internet', 5), 'BB434': Module('BB434', 'Operating Systems', 5), 'BB543': Module('BB543', 'Problem Solving', 5), 'BB432': Module('BB432', 'IT Mathematics', 10)}#ects class Student(object): def __init__(self, idnum, surname, firstname, mods=CA1_MODULES): self.__idnum = idnum self.__surname = surname self.__firstname = firstname self.__mods = mods self.__marks = {code: 0 for code in self.__mods.keys()} #returm a list of module codes #dict comprehension # self.__total_credits self.__total__credits = sum[mod.ects for mod in self.__mods.values()] def __str__(self): name = '{} : {} {}'.format(self.__idnum, self.__firstname, self.__surname) uline = '-' * len(name) results = '\n'.join([code + ' : ' + self.__mods[code].title + ' : ' + str(self.__marks[code]) for code in sorted(self.__mods.keys())]) pm = 'Precision mark: {:.2f}'.format(self.precision_mark()) if self.passed(): outcome = 'Pass' elif self.passed_by_compensation(): outcome = 'Pass by compensation' else: outcome = 'Fail' return '\n'.join([name, uline, results, pm, outcome]) def add_mark(self, module, mark): self.__marks[module]=mark def precision_mark(): [self.__marks[mod] * self.__mods[code].ects for code in self.__mods.keys()] / self.__total_credits def passed(): return min(self__marks.values()) >= 40 def passed_by_compensation(): if self.precision_mark() <45: return False sum([self.__mods[code].ects for code in self.__mods.keys() if self.marks[code] < 40]) > self.__total_credits / 6: return False return min(self.marks.__values()) >= 35 self.__total__credits = sum[mod.ects for mod in self.__mods.values()] ^ #SyntaxError: invalid syntax #self.__total__credits = sum[mod.ects for mod in self.__mods.values()]阵列。您需要append。

尝试：

overwrite

它将用新数组覆盖。
