Question

我想在特定目录中创建文件failure-log.log并将其写入。已经从数据库获取目录路径。路径是这样的：

D:/folder-one/folder-two/

我的PHP代码正在另一个这样的目录中执行：

C:/apache24/crawler/admin/startService.php

如何创建文件并写入文件？

Answer 1

使用file_put_contents方法，如下所示：

numbers

U可以将标志发送到override fun toString() = numbers.toString()，就像$file ="D:/folder-one/folder-two/"; $current = file_get_contents($file); $current .= 'yourcontenthere'; file_put_contents($file, $current);一样：

file_put_contents

在这种情况下，您不必检索旧内容，可以在上面的链接中检查和其他标志。

检查之前是否存在文件也是个好主意。

Answer 2

首先使该文件夹位置可用于Web服务器。然后使用下面的代码在该位置创建文件。

$myfile = fopen("D:/folder-one/folder-two/file.log", "a") or die("Unable to open location for log file !");
$txt = "Log details goes here ...";
fwrite($myfile, $txt);
fclose($myfile);

Answer 3

确保您使用绝对路径（您也可以在相对路径上使用realpath（）以确保该路径）并且目录可写

然后

incl_upp = False
incl_low = False
incl_int = False
incl_sym = False
checklist = []
char_types = []
password = []
length = input('# input length of password in integers | ')
if input('# include upper case alpha? (y/n) | ') == 'y':
    incl_upp = True
    print("# password now includes upper case alpha")
if input('# include lower case alpha? (y/n) | ') == 'y':
    incl_low = True
    print("# password now includes lower case alpha")
if input('# include integers? (y/n) | ') == 'y':
    incl_int = True
    print("# password now includes integers")
if input('# include special characters? (y/n) | ') == 'y':
    print("# password now includes special characters")
    incl_sym = True
if incl_upp == True:
    char_types.append(UPPER_CASE)
    checklist.append(UPPER_CASE)
if incl_low == True:
    char_types.append(LOWER_CASE)
    checklist.append(LOWER_CASE)
if incl_int == True:
    char_types.append(NUMBERS)
    checklist.append(NUMBERS)
if incl_sym == True:
    char_types.append(SYMBOLS)
    checklist.append(SYMBOLS)
while True:
    count = 0
    while count != length:
        case = char_types[random.randint(0,int(len(char_types)-1))]
        char = case[random.randint(0,int(len(case)-1))]
        password.append(str(char))
        count = count + 1
    # for every char in password, for every type in list, for every character in type, check if that is in password
    for i in range(len(password)):
        for x in range(len(checklist)):
            for y in range(len(checklist[x])):
                if checklist[x[y]] in password[i]:
                    checklist[x] = True
    for i in range(len(checklist)):
        if checklist[i] != True or checklist[i] != False:
            checklist[i] = False
    if all(checklist):
        random.shuffle(password) # added security?
        password = "".join(password)
        return password

如果您不想每次都删除文件内容，那么我建议使用FILE_APPEND

$dir = 'your/path';

file_put_contents($dir ."/failure-log.log", $contentOfFile);

Answer 4

写入文件

$writeFile = @fopen('/path/to/save/file', 'w+'); @fwrite($writeFile, $content); @fclose($writeFile);

使用：

w+: will create a new file if it does not exist and overwrite if it exists
a: append to file already exist
a+: append to file already exist and create a new file if it does not exist

如果从数据库加载路径目录，则可能需要创建多目录

if( !is_dir($path) ) { mkdir($path, 0777, true); }

使用：

$path: path you were loaded from db
