<h2 class="title"><em>else</em></h2>
<p class="verinfo">(PHP 4, PHP 5)</p>
<p class="para">
Often you'd want to execute a statement if a certain condition is
met, and a different statement if the condition is not met. This
is what <em>else</em> is for. <em>else</em>
extends an <em>if</em> statement to execute a statement
in case the expression in the <em>if</em> statement
evaluates to <strong><code>FALSE</code></strong>. For example, the following
code would display <span class="computeroutput">a is greater than
b</span> if <var class="varname"><var class="varname">$a</var></var> is greater than
<var class="varname"><var class="varname">$b</var></var>, and <span class="computeroutput">a is NOT greater
than b</span> otherwise:
<div class="informalexample">
<div class="example-contents">
<div class="phpcode"><code><span style="color: #000000">
<span style="color: #0000BB"><?php<br /></span><span style="color: #007700">if (</span><span style="color: #0000BB">$a </span><span style="color: #007700">> </span><span style="color: #0000BB">$b</span><span style="color: #007700">) {<br /> echo </span><span style="color: #DD0000">"a is greater than b"</span><span style="color: #007700">;<br />} else {<br /> echo </span><span style="color: #DD0000">"a is NOT greater than b"</span><span style="color: #007700">;<br />}<br /></span><span style="color: #0000BB">?></span>
</span>
</code></div>
</div>
</div>
The <em>else</em> statement is only executed if the
<em>if</em> expression evaluated to
<strong><code>FALSE</code></strong>, and if there were any
<em>elseif</em> expressions - only if they evaluated to
<strong><code>FALSE</code></strong> as well (see <a href="control-structures.elseif.html" class="link">elseif</a>).
