how to get line by line from txt file and replace variable - php

Question

I want to replace "\n" by " in first line and last line of email
$chekclist = $_POST['emaillist'];
$rwina = explode("\n", "$chekclist");
$i = 0;
$count = 1;
foreach ($rwina as $key => $email[i])

Answer 1

Actually you cannot do that because \n is where the line ends.
I'm assuming that you want your email to format like:
"Lorem ipsum dolor sit amet
consectetur adipiscing elit
sed do eiusmod tempor incididunt
ut labore et dolore magna aliqua."
But the text you'll get from $_POST['emaillist'] will be format like this:
Lorem ipsum dolor sit amet \n
consectetur adipiscing elit\n
sed do eiusmod tempor incididunt \n
ut labore et dolore magna aliqua. \n
So if you want to replace \n with " it will be like this:
Lorem ipsum dolor sit amet"
consectetur adipiscing elit
sed do eiusmod tempor incididunt
ut labore et dolore magna aliqua."
But there is a way to achieve what you are looking for if I'm assuming it right :p
So here's the code:
$chekclist = $_POST['emaillist']; // Get email text
$rwina = explode("\n", "$chekclist"); // Make array
$count = count($rwina); // Count array values
for ($i = 0; $i < $count; $i++) {
if ($i == 0) {
echo '"' . $rwina[$i] . '<br>';
} else if ($i == ($count - 1)) {
echo $rwina[$i] . '"<br>';
} else {
echo $rwina[$i]. '<br>';
}
}
Let me know if this is what you are looking for :)
