Php echo inside a variable - Want to echo that variable

[curb]

I have a php echo code inside a variable I want to echo from another page. I can't seem to echo the "$list_of_teachers" without having it disappear or having it read the code itself.

Here's what I have:

====================

picture-gallery.php

//A picture gallery with variables

$teacher = "Henderson";
$title = "Third Grade Class From Mrs Henderson";
$html = "
<img src='student1.jpg'>
<img src='student2.jpg'>
<br />
Right before lunch and recess
<br />
Email <?php echo \$list_of_teachers[$teacher];?>
";

====================

template.php

//universal template for all galleries

echo "$title <br /> $html";
echo "$link"; //pull data from an array

====================

My Arrays

$list_of_teachers[Henderson] = "[e-mail]";
$list_of_teachers[Smith] = "[e-mail]";

I think what you want is:

$html = "
<img src='student1.jpg'>
<img src='student2.jpg'>
<br />
Right before lunch and recess
<br />
Email {$list_of_teachers[$teacher]}
";

Thanks Nogdog for the reply. I have tried it and the variable disappeared.

Where do you set it?

Hm that was weird. It started working when I replaced the {} with . Thanks NogDog.

What I found when saving a bunch of code to a $var and then writing that $var to a file (file.php) that the PHP code would not execute when called. Turns out the question mark written by php has a different ascii value then the one that triggers the PHP interpreter. So I had to use sprintf("%c", 63) to write the correct question mark so the PHP code will work.

<?php
	// Hex Value of ? so new page will execute php.
	$WritesToFile = '<' . sprintf("%c", 63) . 'php 
	echo "Hello World"; ' 
	. sprintf("%c", 63) . '>';
?>

So using the above code and pretending before its done $WritesToFile is written to a file called (file.php) If you load file.php it will echo "Hello World".

Hope this helps.

NM i see you got it working. Maybe this info will help someone else.

I'm running into this problem again but I don't know why it's not working. I tried \$var and {$var} but it either prints the variable or doesn't echo.

If you view the little code below, the variable $link prints out "<?php echo $school_links;?>" and not the school URL

VARS.PHP

//school vars
  $school_links = "http://www.williamgreen.com/";

MAIN.PHP

<?php
  include('vars.php');

  //link to the specific school website
  $link = '<' . sprintf("%c", 63) . 'php echo $school_links; ' . sprintf("%c", 63) . '>';

  //link sentence
  $letter_template = "If you would like to visit our school website, please visit $link";

  include('website_template.php');
?>

WEBSITE_TEMPLATE.PHP

<?php
  echo "Title of the school";
  echo "$letter_template";
  echo "Header of the school";
?>

Can a mod remove the '[RESOLVED]' on the thread title? Is there a way I can do it myself?

let's have a look at your MAIN code:

<?php
// OK, but make sure this is the correct path from the page which is loaded
  include('vars.php');

  //link to the specific school website
// There really is not need whatsoever for all this sprintf
// The echo is absolutely out of place, as you do NOT wish to echo
// You are in the middle of a string build statement, you cannot use the ;
//  $link = '<' . sprintf("%c", 63) . 'php echo $school_links; ' . sprintf("%c", 63) . '>';

$link = "<a href=\"".$school_links."\">".$school_links."</a>";  

  //link sentence
  $letter_template = "If you would like to visit our school website, please visit $link";

  include('website_template.php');
?>
