removing line breaks in php

Question

As the title reads I am using the echo function to create an h3 string which will insert a php value $lowprice and $highprice. The goal is to have the text read

Here are all the houses whos prices are between $lowprice and $highprice. The code breaks into individual lines like this

Here are all the houses whose prices are between $

100000 and $

500000 :

This is the code I have written, how do I get it all onto one line.

<?php
echo '<caption>';
echo '<h3> Here are all the houses whose prices are between $ </h3>'.$lowprice.'<h3> and $</h3>'.$highprice.'<h3> : </h3>';
echo '</caption>';
?>

Why do you open and close h3 tags multiple times? – vuryss Mar 02 '20 at 23:19 — vuryss, Mar 02 '20 at 23:19

<h3> is a block element, meaning it will take up a whole line. I think you want to replace your inner <h3>'s with <span> tags which are inline elements:

Like this:

<?php
  echo '<caption>';
  echo '<h3> Here are all the houses whose prices are between $ <span>'.$lowprice.'</span> 
  and $<span>'.$highprice.'</span></h3>';
  echo '</caption>';
?>

Or you can simply remove all the inner tags all together, like this:

<?php
  echo '<caption>';
  echo '<h3> Here are all the houses whose prices are between $'.$lowprice.' and $'.$highprice.'</h3>';
  echo '</caption>';
?>

The line breaks appear because you've made several h3 elements. You're closing and reopening h3 tags at every insertion, which is not necessary. The html output of your code is the following:

<h3>Here are all the houses whose prices are between $</h3>
<h3>100000 and $</h3>
<h3>500000 : </h3>

Which automatically adds breaks, since that is the behaviour of h3 elements.

What you need is this:

echo '<h3> Here are all the houses whose prices are between $'.$lowprice.' and $'.$highprice.':</h3>';

Better yet, don't use echo to define your html; html and php are interchangeable within the same file. A cleaner, more readable and more easily maintainable solution would be to form your script like this:

<caption>
    <h3>Here are all the houses whose prices are between $<?= $lowprice ?> and $<?= $highprice ?>:</h3>
</caption>

Generally, you switch between php and html like this:

<?php
...do some php
?>
<somehtml></somehtml>
<?php do some more php ?>
<morehtml>...

Note that <?= is a shorthand for <?php echo.

Thanks for the info on the shorthand and the help Im going to close this post because its been answered — Chris Lynch, Mar 02 '20 at 23:37
