如何在 php 中编写 html 代码？

Question

I want to write some html code in php. In this html code I am calling a javascript function. but while it is calling the function there is a problem. I think the problem is quotes but I couldn't fix it.

This is the html code that I want to put inside php.

<table>
 <tr>
 <a href="javascript:chng('img');"><img src="s.png" name="img"></a> 
 </tr>
</table>

and this is my javascript code;

<script type="text/javascript">
img1 = "s.png";
img2 = "k.png";
function chng(c_img) {
if (document[c_img].src.indexOf(img1)!= -1) document[c_img].src = img2;
else document[c_img].src = img1;
} 

</script>

How can i write this html inside php code?

Thanks

Answer 2

you also could wrap your code in heredoc, and echo it afterwards http://www.php.net/manual/de/language.types.string.php#language.types.string.syntax.heredoc

Answer 3

you could echo the html; eg

echo "<table>
 <tr>
 <a href=\"javascript:chng('img');\"><img src=\"s.png\" name=\"img\"></a> 
 </tr>
</table>
";

Just escape the double quotes with a backslash.

Answer 4

You can use PHP heredoc syntax:

var $js = <<<JS

// code

JS;

Escapes and echo "<html_code>" is a noob style.

Answer 5

Use scriptlets and the command echo.

<?
  echo "<script type=\"text\/javascript\">"
?>

and so far. But pay attention of masking quotations signs and backslashes, etc.

Write html tags inside php code isn't nice. Read about templates to php as Smarty
