I knew th开发者_开发问答ere are two ways to represent PHP code start/end.
<?php ?>
and
<? ?>
In this code snippet:
<?php
for($x=5;$x<25;$x=$x+5):
$List .= '<option value="'.$x.'">Greater than '.$x.'% increase</option>';
endfor;
?>
<html>
...
<select name="growth" id="growth">
<option value="">Choose one</option>
<?=$List ?>
</select>
...
</html>
What is the meaning of the <?=$List ?>?
<? is the shorthand version of the opening tag, <?php. The = means to echo the specified string/variable, so the whole thing is shorthand for:
<?php
echo $List
?>
<?php echo $List ?>
The shorttag syntax is deprecated though.
