如何在PHP文件fwrite中添加新行 [英] How to put new line in php file fwrite
问题描述
我正在写的文件是plan.php
.这是我正在编写的php文件.我正在使用\n
将新行放入该文件中,但它为我提供了保存输出.
I am writing a file that is plan.php
. It is a php file that I am writing. I am using \n
to put the new line in that file but it is giving me save output.
这是代码:
$datetime = 'Monthly';
$expiry = '2017-08-07';
$expiryin = str_replace('ly', '',$datetime);
if($expiryin == 'Month' || $expiryin == 'Year') {
$time = '+ 1'.$expiryin.'s';
} else {
$time = '+'.$expiryin.'s';
}
$expiry_date = date('Y-m-d', strtotime($time, strtotime($expiry)));
$string = createConfigString($expiry_date);
$file = 'plan.php';
$handle = fopen($file, 'w') or die('Cannot open file: '.$file);
fwrite($handle, $string);
函数是:
function createConfigString($dates){
global $globalval;
$str = '<?php \n\n';
$configarray = array('cust_code','Auto_Renew','admin_name');
foreach($configarray as $val){
$str .= '$data["'.$val.'"] = "'.$globalval[$val].'"; \n';
}
$str .= '\n';
return $str;
}
但是它给出的输出如下:
But it is giving the output like:
<?php .......something....\n.....\n
所以我的问题是如何在该文件中放入新行.
So my question is how to put the new line in this file.
注意:代码中没有错误.我已经最小化了要放在这里的代码.
Note: There is no error in code. I have minimized the code to put here.
推荐答案
每个人都已经提到过'\n'
只是两个符号字符串\n
.
As everyone already mentioned '\n'
is just a two symbols string \n
.
您需要"\n"
或php核心常量PHP_EOL
:
You either need a "\n"
or php core constant PHP_EOL
:
function createConfigString($dates){
global $globalval;
// change here
$str = '<?php ' . PHP_EOL . PHP_EOL;
$configarray = array('cust_code','Auto_Renew','admin_name');
foreach($configarray as $val){
// change here
$str .= '$data["'.$val.'"] = "'.$globalval[$val].'";' . PHP_EOL;
}
// change here
$str .= PHP_EOL;
return $str;
}
