I am setting the value of a php variable to some html. i.e.
$_img = 'hehehehehe';
The variable is then shown in html after a br tag. But it doesn't execute the html in it. Rather it displays it like hehehehehe. So, is there any problem in my code! How can i do this thing?
Here is the code that displays that IN HTML,
<?php if ($_item->getComment()): ?> <br/><?php echo $this->escapeHtml($_item->getComment(), array('b','br','strong','i','u')) ?> <?php endif; ?>
<?php
$string = 'Hehehe';
echo $string;
?>
This works fine! The html is 'executed' and the link is displayed.
From your comment....
Here is the code that displays that <?php if ($_item->getComment()):
?> <br/><?php echo $this->escapeHtml($_item->getComment(),
array('b','br','strong','i','u')) ?> <?php endif; ?>
As predicted by many people, it looks like you are encoding the value when you display it.
I don't know what the $this->escapeHtml function is doing exactly, but it would appear to be doing an HTML Encoding on the string.
The result being that any tag, for example <a> will be sent to the browser as <a> which the browser will display as <a>. The browser will not see it as a tag, and will therefore not treat it as one.
So the simple answer is: don't encode the HTML...
<?php echo $_item->getComment(); ?>
I suspect you are just echoing the variable.
You need use the 'htmlspecialchars' method such as below.
<?php
$new = htmlspecialchars("<a href='test'>Test</a>", ENT_QUOTES);
echo $new; // <a href='test'>Test</a>
?>

<?php echo str_repeat('', 1) htmlencode('$postcode_coveringsRecord['postcode']) ?>
<?php echo htmlencode(' $postcode_coveringsRecord['postcode']) ?>
<?php echo htmlencode('. $postcode_coveringsRecord['postcode'].) ?>
<?php echo ' ''htmlencode('$postcode_coveringsRecord['postcode'])' ?>
<?php echo htmlencode(' ''$postcode_coveringsRecord['postcode']) ?>
How can I minipulate
where as the variable gives me one blank space prior to the variable content.
cheers for any input

These ones should work
echo ' '.htmlencode($postcode_coveringsRecord['postcode']);
or
echo ' '.htmlencode($postcode_coveringsRecord['postcode']);
I currently have a php which echo my html template.
However in that HTML template there is another echo which calls from another php script.
Just wondering how do I do that? Because once I echo my html template the other it doesn't seems to echo my content from the other php script.
HTML TEMPLATE
<php? $html = '<span>name:<?php echo $name; ?></span><span>email:<?php echo $email; ?></span>' ?>
CONTACT TEMPLATE
<php? $name = "hello world"; $email = "hello#world.com"; ?>
I can see what you're trying to do, and it's a simple error. You can't escape php like that whilst inside setting a variable.
Also, I must add that you are declaring php incorrectly.
This is preferred
<?php
not
<php?
So make sure for your contact template you use the correct tag.
Also to include a file you have to call it/require it.
Back to the original question - Here is your method
<php? $html = '<span>name:<?php echo $name; ?></span><span>email:<?php echo $email; ?></span>' ?>
Here is the correct method
<?php
require('contact.php');
$html = '<span>name:'.$name.'</span><span>email:'.$email.'</span>';
echo $html;
?>
First I created the variable. And when doing so I insert the existing variables by escaping the php. Only once this final variable is created do I echo it.
Hope this helps you on your way.
Try to use include. The include statement includes and evaluates the specified file, in this case - your template.
Just Concatenation
<?
$html = '<span>name:'.$name.'</span><span>email:'.$email.'</span>';
?>
Change the tags from <php? ?> to <?php ?> in your script
How can I use the HTML <code> element to output a block of PHP code, without the page running that PHP code? Eg;
<pre><code>
<?php
// Some super duper PHP code
?>
</code></pre>
I'm creating an API docs page, which features snippets of PHP that anyone wishing to use the API can use as examples, but anything wrapped in <?php> tags runs as an actual PHP function
Use <?php and ?>.
The HTML entities will show up as PHP opening and closing tags when the page is rendered, but PHP will obviously not see them. But you have to html-escape your code anyways, otherwise contained HTML-tags will be rendered. So there should be
<?php echo 'Hello, World.<br>'; ?>
Another way would be to have a string specified by a nowdoc and then output html-escaped (demo):
<?php
$code = <<<'EOC'
<?php
echo 'Hello, World.<br>';
// ...your code here...
?>
EOC;
echo htmlentities($code);
?>
Have look for different approaches at How do I display PHP code in HTML?.
Do this via PHP like so:
<?php
$code = '<?php
echo "Hello, World!";
?>';
echo '<code>' . htmlspecialchars($code) . '</code>';
?>
try something like this:
<?php echo '<?php'; ?>

I am testing this on windows 7 xammp 1.8.1 php 5.4.7
I am trying to show dynamic php codes in html as example
my code is
<?php
$output="<?php echo $ti ?>";
echo $output;
?>
but output html is blank! i am not sure if its a bug, can some help me.thanks in advance
When you run this, this DOES produce an output, which is a blank page, because the output is:
<?php echo ?>
To a browser which renders html, it will look like an open tag with nothing in value.
Run your script and view the page source...
You need to use single quotes
i.e.
change
<?php
$output="<?php echo $ti ?>";
echo $output;
?>
to
<?php
$output='<?php echo $ti ?>';
echo $output;
?>
Just change your double quotes to single quotes:
<?php
$output='<?php echo $ti ?>';
echo $output;
?>
Example: http://ideone.com/bUJAxb
There are two things you have to change. First, if you use double quotes PHP will evaluate variables in it, so your output will be <?php echo ?>:
$output='<?php echo $ti ?>';
Now the output will be <?php echo $ti ?>.
Next, the browser will interpret this as HTML and since it is only a single tag it will display nothing. You need to run this through htmlentities():
echo htmlentities($output);
This will output <? echo $ti ?;gt; which will be displayed by the browser in the way you intend it.
You need to escape the characters
This can be done by adding the entire line you want to output in an htmlentities function call, like:
$output = htmlentities("<?php echo \$ti ?>");
PHP echo function is not outputing strings in the format of html tag like <something. somethong_else>, may be because it is like HTML tags, is there any way to display it?
echo 'hi<h.i>';
Eg : this displays as
echo 'hi';
try using
<?php
echo htmlentities('hi<h.i>');
?>
You need to encode the string if you what the text to appear
echo htmlentities("hi<h.i>");
There is a thing called HTML. Where strings in <something.somethong_else> format have some meaning. Go figure.
PHP can echo out tags.
Example
<?php
echo '<p>Hello World</p>';
?>
Keep in mind, the PHP will echo where it is called. So you can also do this
<p>
<?php echo 'Hello World'; ?>
</p>
UPDATE
Since new information is sent. You can make < into < and > into > Look at HTML entities.
You probably need to use htmlentities(), try this:
echo htmlentities('hi<h.i>');
