html form not displaying values
Question
Scenario: I have this simple HTML 5 Form inside the PHP tag.
<?php
echo '
<form method="post" action="index.php">
<input type="email" name="email value="<?php echo $email; ?>">
<input type="password" name="password">
<button type="submit" name="signin">Sign in</button>
</form>
';
?>
The form displays correctly but I can not get the value of $email, it just displays as raw text.
So, how to echo a php variable from a form inside a PHP tag.
FINAL CODE
<?php
echo '<form method="post" action="index.php" class="navbar-form navbar-right">
<input type="email" name="email" placeholder="Email" class="form-control1" value="' . $email . '">
<input type="password" name="password" placeholder="Password" class="form-control">
<button type="submit" name="signin">Sign in</button>
</form>';
?>

Try Closing the Form tag:
<?php
echo '
<form method="post" action="index.php">
<input type="email" name="email"value="<?php echo $email; ?>">
<input type="password" name="password">
<button type="submit" name="signin">Sign in</button>
</form>
';
?>

You need to escape out from the string with ' and concatenate with . that way you can use php variables into an string
<?php
echo '
<form method="post" action="index.php">
<input type="email" name="email "value="' . $email .'">
<input type="password" name="password">
<button type="submit" name="signin">Sign in</button>
</form>
';
?>
Or like said in the comment, place the html code after your php closing tag
<?php
// Do some code
?>
<form method="post" action="index.php">
<input type="email" name="email "value="<?= $email; ?>">
<input type="password" name="password">
<button type="submit" name="signin">Sign in</button>
</form>

if you want to access your variables for an echo statement you have to use double quotes. and you can put single quotes inside double quotes.
$email = "example@gmail.com";
echo "
<form method='post' action='index.php'>
<input type='email' name='email' value='$email'>
</form>
";
or even using Heredoc
$email = "example@gmail.com";
echo <<<HTML
<form method="post" action="index.php">
<input type="email" name="email" value="$email">
<input type="password" name="password">
<button type="submit" name="signin">Sign in</button>
</form>
