Novice ask PHP strange problem?

潜水已俩月

The php source files are as follows:

1 <form method = post name = list action = list_all.php>
2 <input type = hidden name = page value = <? = $ Page? >>
3 <input type = hidden name = id value = <? = $ Id? >>
4 <input type = hidden name = select_arrange value = <? = $ Select_arrange? >>
5 <input type = hidden name = desc value = "<? = $ Desc?>">
6 <input type = hidden name = page_num value = <? = $ Page_num? >>
7 <input type = hidden name = selected>
8 <input type = hidden name = exec>
9 <input type = hidden name = keyword value = "<? = $ Keyword?>">
10 <input type = hidden name = sn value = "<? = $ Sn?>">
11 <input type = hidden name = ss value = "<? = $ Ss?>">
12 <input type = hidden name = sc value = "<? = $ Sc?>">

From the browser "View Source File" you can see the returned content to:
...
<input type = hidden name = desc value = "

That's all there is to stop! That is to say, this code will terminate when it reaches the variable $ desc on line 5. It should be a problem with variable $ desc, but I output it with echo before the first line. But it shows that the value is "asc"
And I delete the 5th line. The same error will continue to appear on the 6th line, ... the 9th line, the 10th line, the 11th line ...

This problem is really weird. The younger brother is a novice again. It is really the second monk who is scratching his head. Here I would like to ask your predecessors how to solve it, younger grateful!

1 It is recommended that those with double quotes should be marked with
2 It can also be written like this: <input type="hidden" name="page" value="<? echo $page;?>">

There are double quotes in $desc, change to <?=htmlspecialchars($desc)?>

The string is enclosed in quotation marks and is at least common sense

Write according to the standard. Attribute double quotes.

Thank you very much for your suggestions, but I have not been able to solve the problem according to your methods! Even the method on the 3rd floor will not work. Can anyone really solve this problem?

What you said is to add double quotes in the attribute. I agree, but it is obvious that the problem should be in the php program, that is, the variable $desc,
It has nothing to do with html because the PHP has been terminated when it reaches the variable!

The problem is still there, I hope there is a senior who can advise me again! Thank you very much!

The code is very irregular, this should pay attention

Use the value attribute, otherwise...

1 <form method=post name=list action=list_all.php>
2 <input type=hidden name=page value='<?=$page?>'>
3 <input type=hidden name=id value='<?=$id?>’>
4 <input type=hidden name=select_arrange value='<?=$select_arrange?>'>
5 <input type=hidden name=desc value='<?=$desc?>'>
6 <input type=hidden name=page_num value='<?=$page_num?>'>
7 <input type=hidden name=selected>
8 <input type=hidden name=exec>
9 <input type=hidden name=keyword value='<?=$keyword?>'>
10 <input type=hidden name=sn value='<?=$sn?>'>
11 <input type=hidden name=ss value='<?=$ss?>'>
12 <input type=hidden name=sc value='<?=$sc?>'>

Of course, please use echo to output all the variables. Also, it is better to use <?php ?> tags
