How to write file as it is? - php

Question

I have a string of code like this:
<?php
echo "Hello World";
?>
Now, I want to write that into a php file just the way it is. What I mean is that I want to write this code with new line characters. So the code gets stored in the above fashion. So, how can I do that?
I had tried to use file append and fwrite, but they write the code in one consecutive line and what I want is to have it divided into 3 lines.
On the first line - <?php
On the second line - echo "Hello world";
On the third line - ?>
But I would like to do it by using only one line of code, that would be something like the below one.
$file = 'people.php';
// The new person to add to the file
$person = "John Smith\n";
// Write the contents to the file,
// using the FILE_APPEND flag to append the content to the end of the file
// and the LOCK_EX flag to prevent anyone else writing to the file at the same time
file_put_contents($file, $person, FILE_APPEND | LOCK_EX);

Answer 1

This should work fine using an heredoc:
file_put_contents('people.php', <<<HEREDOC
<?php
echo "Hello World";
?>
HEREDOC
);

Answer 2

<?php
$File = "new.txt"; //your text file
$handle = fopen($File, 'w');
fwrite($handle, '<?php '."\n".' echo "Hello World "; '."\n".'?>');
?>

Answer 3

Your string should be like this
$str = "<?php
echo \"Hello World\";
?>";
then write it to any fileName.php, php while parsing ignores new lines, only semicolons matters.
Edit 1
Since you want to write your string as code, after following above step you will have all your code in a single line more like a compressed code, which will be not human readable, for making it human friendly, you will have to add formatting, a minimal approach for formatting will be to at least add new line chars and tabs for indentation.
for this you will have to do two things, identify chars (a) where you need to add new line feed and those chars (b) where indentation is required. Now before writing to file do some preprocessing add new line chars for char type (a) and at the same time maintain a stack for adding proper number of tabs for indentation.

Answer 4

Try using the following between each line of code to put it on a new line in the php file:
. PHP_EOL .

Answer 5

You can:
<?php
$yourContent = <<<PHP
<?php
echo "Hello world";
echo "This in an example";
$foo = 2;
$bar = 4;
echo "Foo + Bar = ".($foo+$bar);
?>
PHP;
file_put_contents("yourFile.php", $yourContent);
?>

Answer 6

Try following :
<?php
$file = "helloworld.php";
$content = file_get_contents($file);
print_r(htmlspecialchars($content));
?>
Helloworld.php :
<?php
echo "Hello World";
?>
It'll work fine.

Answer 7

It sounds like you need to add a line break to the end of each line. You can use a regular expression search/replace as follows (where $newData already contains the string you want to append to the file):
<?php
$newData = preg_replace('/$/',"\n", $newData);
file_put_contents($file, $newData, FILE_APPEND | LOCK_EX);
?>
This finds the end of each line (indicated by $ in regex) and adds the new line (\n) at that position.

Answer 8

this code is working on my pc. you will also like it.
<?php
$file = 'people.php';
// The new person to add to the file
$person = "<?php
echo 'Hello World';
?>\n";
// Write the contents to the file,
// using the FILE_APPEND flag to append the content to the end of the file
// and the LOCK_EX flag to prevent anyone else writing to the file at the same time
file_put_contents($file, $person, FILE_APPEND | LOCK_EX);
echo $person;
?>
