PHP - I can't trim off the last character which is a space

Question

My HTML form:

<form action="http://localhost/wordpress" id="search" method="get">
<input type="text" size="30" id="s" name="s" value="Type and hit enter" onfocus="javascript:this.value='';" onblur="javascript:this.value='Type and hit enter';"/>
<br/>
<input type="submit" value="Search"/>
</form>

My PHP script:

<div class="message">
You searched for: 
<?php 
$searchterms = explode(" ", $_GET["s"]);
foreach ($searchterms as $searchterm) {
$length = strlen($searchterm);
$searchterm = substr($searchterm, 0, $length-1); ?>
<span class="searchterm"><?php echo $searchterm." "; ?></span>
<?php } ?>
</div>

It cuts off the last alphabet AND leave the darn space behind ><

Answer 1

Why not just use the trim() function on every element of the exploded array?

Answer 2

Use trim(), or rtrim(), or ltrim().

Answer 3

Isn't it because you manually add a space when you echo $searchTerm? ;-)

Your code looks fine, I would just remove the substr, explode removes the whitespace between keywords.

If you really want to ensure you have no whitespaces around your keywords, you can use the trim function.
