I have a for loop that displays radio buttons and I want the first one to display as checked. But when I put a if statement inside the for loop for this the page nevers loads. Any ideas?
$mains = array(0=>'Beef Steak', 1=>'Chicken Breast', 2=>'Pork Chops');
$mainscount = count($mains);
<?php for ($mainNO = 0; $mainNO < $mainscount; $mainNO++) { ?>
<label for="mains<?php echo $mainNO ?>" class="radiobutton"><?php echo $mains[$mainNO]; ?></label>
<input type="radio" name="mains" id="mains<?php echo $mainNO; ?>" value="<?php echo $mainNO; ?>"
<?php if($mainNO = 0){ echo 'checked="checked"'; } ?>/>
<?php } ?>

// Note: You used single = in if condition that is wrong, it will create indefinite loop . Tested code.
$mains = array(0=>'Beef Steak', 1=>'Chicken Breast', 2=>'Pork Chops');
$mainscount = count($mains);
for ($mainNO = 0; $mainNO < $mainscount; $mainNO++) {
// Checked if value is 0
if($mainNO == 0){ $checked = 'checked="checked"'; }else { $checked =''; };
echo "<label for='mains".$mainNO."' class='radiobutton'>".$mains[$mainNO]."</label>";
echo "<input type='radio' name='mains' id='mains".$mainNO."' value='".$mainNO."' $checked />";
}

u are using assingment operator in comparision statement
<?php for ($mainNO = 0; $mainNO < $mainscount; $mainNO++) { ?>
<label for="mains<?php echo $mainNO ?>" class="radiobutton"><?php echo $mains[$mainNO]; ?></label>
<input type="radio" name="mains" id="mains<?php echo $mainNO; ?>" value="<?php echo $mainNO; ?>"
<?php if ($mainNO == 0) {
echo " checked";
} ?>/>
and in HTML5 you can use checked only
<input type="checkbox" checked>

<?php for ($mainNO = 0; $mainNO < $mainscount; $mainNO++) { ?>
<label for="mains<?php echo $mainNO ?>" class="radiobutton"><?php echo $mains[$mainNO]; ?></label>
<input type="radio" name="mains" id="mains<?php echo $mainNO; ?>" value="<?php echo $mainNO; ?>"
<?php if ($mainNO == 0) {
echo ' checked="checked" ';
} ?>/>
<?php } ?>
