echo get($contents,'<plaintext>','</plaintext>') ;

Now i want to format this echo text with increase the font size

echo "<div style ='font:30px Arial,tahoma,sans-serif;color:#555'>get($contents,'<plaintext>','</plaintext>') </div>";
but it is not working how to do this??
I try this by doing more experiment but none of the things working.
plz help me on this
You need to append the function in the string. Just like this:
echo "<div style ='font:30px Arial,tahoma,sans-serif;color:#555'>" . get($contents,'<plaintext>','</plaintext>') . "</div>";

Please help me to understand syntax of concat following

I try following code but getting syntax error that there is two echo..
2--> echo "<div class=\"alert" . echo $_REQUEST['error_id']; . "\">";
where mistake is that i cant get it... and i want two answer both using single quote and double quote
EDIT
Thank #Rizier123 now it working but css is not working as i have apply in calss="alert"
while using following code its working fine
<div class="alert echo $_REQUEST['error_id'];?>"\>
But after applying your code its not working..only text appear but background color is not comming nad boarder is also dissappear as below
class name is alert shows the status of login..
EDIT
Thanks again i just forget to put space after class name..
You don't need to write echo and ; again!
So this should work:
//echo with double quotes
echo "<div class=\"alert" . $_REQUEST['error_id'] . "\">";
//echo with single quotes
echo '<div class="alert' . $_REQUEST['error_id'] . '">';
Maybe you need to add a space if your class name includes spaces!(..."alert "...)
try this
echo '<div class=\"alert"' . $_REQUEST['error_id'] . '">';
You can do either 2 ways
1. PHP in HTML
<div class="alert<?php echo $_REQUEST['error_id'];?>">
2. HTML in PHP
echo "<div class='alert". $_REQUEST['error_id'] ."'>";
Or you can also do like
echo "<div class=\"alert". $_REQUEST['error_id'] ."\">";
Is this possible?
What I am trying to accomplish:
Create a html template in the form of a string
Inside the string, add a script, something like include 'php/countries.php';
Echo entire string to html page
Everything but the 2nd step works. I would like to see a php file echo the question being asked, onto the html page, including an echo from another php file.
EXAMPLE
echo "<div id=\"first\"><?php include \'countries.php\'; ?></div>";
I have tried the above, as well as the below:
EXAMPLE
echo "<div id=\"first\">".include 'countries.php'."</div>";
Would this require eval?
Any and all help is appreciated.
Seems a bit silly, but you could do the following:
echo "<div id=\"first\">" . file_get_contents('countries.php') . "</div>";
Or...
echo "<div id=\"first\">";
include "countries.php";
echo "</div>";
Or...
$externalfile = compileexternal('countries.php');
function compileexternal($file) {
ob_start();
require $file;
return ob_get_clean();
}
echo "<div id=\"first\">" . $externalfile . "</div>";
If none of these are what you need, please update the question. There are a dozen ways.
You can use
eval()
But it is not a good practice.
You can use a regular expression.
For example, your string could be;
<div id="first">{{countries.php}}</div>
You'd then do;
$string = "<div id='first'>{{test2.php}}</div>";
echo preg_replace_callback("/(\{\{.+\}\})/", function($matches) {
include_once( str_replace(array("{", "}"), "", $matches[0]));
}, $string);
Check the file exists if( file_exists() )
Check the file can be included (we don't want to include ../../../../../etc/passwd
I have the following line of code which doesn't seem to be working:
echo "<img src='/images/albumart'"; echo $row['art1']; echo "/>";
The 'art1' is definitely returning '/imagename.png' so the URL should be complete however nothing being displayed.
Any ideas?
Thanks.
You really should be concatenating that string:
<?php
echo '<img src="/images/albumart'.$row['art1'].'"/>';
?>
and ideally break out of php to do this:
<img src="/images/albumart<?php echo $row['art1']; ?>"/>
If you're not familiar, the period in php joins strings. That's called concatenation. No need to echo little bits like that, in fact please never do it the way you demonstrate. The root of your issue is, as Geoff pointed out, you weren't closing the src param.
echo "<img src='/images/albumart'"; echo $row['art1']; echo "/>";
It looks like you are closing the img src paramter after the albumart part.,
try this:
echo "<img src='/images/albumart"; echo $row['art1']; echo "' />";
I am trying to style a sentence within php by trying to echo the div. However the styling is not being applied. The css is correct, I think I have something wrong on how I am calling a div withing php. Can you please advise.
This what I have tried:
echo '<div id="sumtitle">' . "<tr><td>" . "This is a test" . "</td></tr>" . '</div>';
tried also like this:
echo '<div id="test">Test sentence</div>';
thanks
PHP is not responsible for styling.
You have to check your styles file or whatever.
Check your HTML and CSS.
PHP has nothing to do here.
The code looks OK, although the multiple use of the . in the first is unnecessary. You could just put:
echo '<div id="sumtitle"><tr><td>This is a test</td></tr></div>';
BTW: Are you using a <table> for your <tr> and <td>?
Regardless, the styling should work fine if you use something like:
#sumtitle { font-style: italic; }
or
#test {...}
I'd double check the CSS! :)
echo "<img src='bloginfo('template_url').'/img/'.$img' />";
