语法错误，意外的T_ENCAPSED_AND_WHITESPACE，预期为T_STRING或T_VARIABLE或T_NUM_STRING [英] syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING
问题描述
我已经盯着这个代码好几个小时了，但我不知道我的错误在哪里.我知道这种语法错误通常是由于缺少大括号或错位或单/双引号引起的，因此我不确定代码中是否有任何错误.我现在仅尝试修复语法，以便使代码完全编译.任何帮助将非常感激.这是我的代码:
I have been staring at this code for hours now and I cannot figure out where my mistake is. I know this syntax error usually comes up because of some missing or out of place curly brace or some issue with single/double quotes and I'm not sure there is one anywhere in my code. I am only trying to fix my syntax right now so I can get the code to completely compile. Any help would be much appreciated. Here is my code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<body>
<?php
function print_form() {
echo <<<END
<form action="$_SERVER[PHP_SELF]" method="post">
<h3>Please put your comments below.</h3>
<input type="hidden" name="stage" value="process" >

<p>Comment:</p>

END;
}
function process_form() {
print "<p>adding comment...</p>";
$Name = $_POST['WholeName'];
$Comment = $_POST['Comment'];
if( preg_match("^[a-zA-Z]+$", $Name)) {
if( preg_match("^[a-zA-Z0-9]_\-\'[.?!]+$", $Comment)) {
$sql = "insert into comments1 values (

'$Comment')";
$result = mysql_query($sql) or die("Mysql query failed");
} else {
print "invalid name";
}
} else {
print "invalid characters";
}
}
$db = mysql_connect("", "", "");
if (!$db) {
print "Error - Could not connect to mysql";
exit;
}
$er = mysql_select_db("");
if (!$er) {
print "Error - Could not connect to comments1 database";
exit;
}
if (isset($_POST['stage']) && ('process' == $_POST['stage'])) {
process_form();
} else {
print_form();
}
?>
</body>
</html>
推荐答案
您的问题是您没有正确关闭HEREDOC.包含END; 的行中不得包含任何空格之后 .
Your problem is that you're not closing your HEREDOC correctly. The line containing END; must not contain any whitespace afterwards.
