我一直在寻找官方的php文档,但我无法找到我正在寻找的内容。
http://php.net/manual/en/function.parse-ini-file.php
我只想要一个函数来编辑和读取php ini文件中的值,例如,
[default_colors]
sitebg = #F8F8F8
footerbg = #F8F8F8
link = #F8F8F8
url = #F8F8F8
bg = #F8F8F8
text = #F8F8F8
border = #F8F8F8
lu_link = #F8F8F8
lu_url = #F8F8F8
lu_bg = #F8F8F8
lu_text = #f505f5
lu_border = #F8F8F8

您只需将parse_ini_file
与PHP4 / 5一起使用即可。
$ini_array = parse_ini_file("sample.ini");
print_r($ini_array);
以下是文档:http://php.net/manual/en/function.parse-ini-file.php
要将一组对象写回到ini文件中,请使用下面的快速&简单的解决方案:
function write_php_ini($array, $file)
{
$res = array();
foreach($array as $key => $val)
{
if(is_array($val))
{
$res[] = "[$key]";
foreach($val as $skey => $sval) $res[] = "$skey = ".(is_numeric($sval) ? $sval : '"'.$sval.'"');
}
else $res[] = "$key = ".(is_numeric($val) ? $val : '"'.$val.'"');
}
safefilerewrite($file, implode("\r\n", $res));
}
function safefilerewrite($fileName, $dataToSave)
{ if ($fp = fopen($fileName, 'w'))
{
$startTime = microtime(TRUE);
do
{ $canWrite = flock($fp, LOCK_EX);
// If lock not obtained sleep for 0 - 100 milliseconds, to avoid collision and CPU load
if(!$canWrite) usleep(round(rand(0, 100)*1000));
} while ((!$canWrite)and((microtime(TRUE)-$startTime) < 5));
//file was locked so now we can store information
if ($canWrite)
{ fwrite($fp, $dataToSave);
flock($fp, LOCK_UN);
}
fclose($fp);
}
}

这个怎么样:
$key='option';
$val='1.2.3.4.5';
system("sed -ie 's/\({$key}=\)\(.*\)/\1{$val}/' file.in");

下面是PHP目前缺少的write_ini_file()
的实现,它将创建输入几乎相同的(注释除外):
PHP_EOL
)新行。<强>来源
<?php
if (!function_exists('write_ini_file')) {
/**
* Write an ini configuration file
*
* @param string $file

* @return bool
*/
function write_ini_file($file, $array = []) {
// check first argument is string
if (!is_string($file)) {
throw new \InvalidArgumentException('Function argument 1 must be a string.');
}
// check second argument is array
if (!is_array($array)) {
throw new \InvalidArgumentException('Function argument 2 must be an array.');
}
// process array
$data = array();
foreach ($array as $key => $val) {
if (is_array($val)) {
$data[] = "[$key]";

// empty line
$data[] = null;

// open file pointer, init flock options
$fp = fopen($file, 'w');
$retries = 0;
$max_retries = 100;
if (!$fp) {
return false;
}
// loop until get lock, or reach max retries
do {
if ($retries > 0) {
usleep(rand(1, 5000));
}
$retries += 1;
} while (!flock($fp, LOCK_EX) && $retries <= $max_retries);
// couldn't get the lock
if ($retries == $max_retries) {
return false;
}
// got lock, write data
fwrite($fp, implode(PHP_EOL, $data).PHP_EOL);
// release lock
flock($fp, LOCK_UN);
fclose($fp);
return true;

示例输入.ini
文件(取自http://php.net/manual/en/function.parse-ini-file.php)
; This is a sample configuration file
; Comments start with ';', as in php.ini
[first_section]
one = 1
five = 5
animal = BIRD
[second_section]
path = "/usr/local/bin"
URL = "http://www.example.com/~username"
[third_section]
phpversion[] = "5.0"
phpversion[] = "5.1"
phpversion[] = "5.2"
phpversion[] = "5.3"
urls[svn] = "http://svn.php.net"
urls[git] = "http://git.php.net"
使用示例:
// load ini file values into array
$config = parse_ini_file('config.ini', true);
// add some additional values
$config['main']['foobar'] = 'baz';
$config['main']['const']['a'] = 'UPPERCASE';
$config['main']['const']['b'] = 'UPPER_CASE WITH SPACE';
$config['main']['array'][] = 'Some Value';
$config['main']['array'][] = 'ADD';
$config['third_section']['urls']['docs'] = 'http://php.net';
// write ini file
write_ini_file('config.ini', $config);

这是一个功能版本,可以创建一个可以写入文件的字符串。
function IniAsStr(array $a) : string
{
return array_reduce(array_keys($a), function($str, $sectionName) use ($a) {
$sub = $a[$sectionName];
return $str . "[$sectionName]" . PHP_EOL .
array_reduce(array_keys($sub), function($str, $key) use($sub) {
return $str . $key . '=' . $sub[$key] . PHP_EOL;
}) . PHP_EOL;
});
}

这是您使用类别选项读取和写入INI 文件的功能!
如果提供多维数组,则INI文件中将包含类别。 或者基本数组将使您可以快速读取和写入数据。
有关详细信息,请参见下面的评论和示例:
$ sed -e 's:AND:\n&:g' -e 's:GROUP BY:\n&:g' -e 's:UNION:\n&:g' -e 's:FROM:\n&:g' file > readable.sql
答案 6 :(得分:-15)
您只需使用ini_set('lu_link','#000000');
或ini_get('lu_link')
。
我觉得,如果你的PHP经验有限,那么弄乱.ini
文件是不好的。
