how to streamline if, else

[siobhan]

I need to assign variables (see $imagefile... below), then run if, else statements on each variable separately and then display the image if the filepath exists, what is the best way to do this without ending up with a lot of repeated code?

<?php

$name = $row_rs_dgame['name'];
$name2 = str_replace(" ", "",$name);
$imagefileanim = 'images/'.$name2.'/'.$name2.'/moving/'.$name2.'Anim_1.gif';
$imagefile1 = 'images/'.$name2.'/'.$name2.'/screenshots/'.$name2.'1.txt';
$imagefile2 = 'images/'.$name2.'/'.$name2.'/screenshots/'.$name2.'1.txt';
$imagefile3 = 'images/'.$name2.'/'.$name2.'/screenshots/'.$name2.'1.txt';
$imagefile4 = 'images/'.$name2.'/'.$name2.'/screenshots/'.$name2.'_1.txt';
?>
<?php
if (file_exists($imagefileanim)) {
// display image
} else {
echo "The file $imagefileanim does not exist";
}
?>

<?
$name = $row_rs_dgame['name'];
$name2 = str_replace(' ', '', $name);
$path_array['imagefileanim'] = 'images/' . $name2 . '/' . $name2 . '/moving/' . $name2 . '_Anim_1.gif';

for ($i = 1; $i <= 4; $i++)
{
	$path_array['imagefile' . $i] = 'images/' . $name2 . '/' . $name2 . '/screenshots/' . $name2 . '_' . $i . '.txt';
}

foreach ($path_array as $key => $value)
{
	if (file_exists($value))
	{ 
		// display image 
	}
	else
	{ 
		echo 'The file ' . $key . ' does not exist<br>'; 
	}
}
?>

That worked well, just had to fix my mistake of naming image files with .txt extensions instead of .gif!

I do have one more question though. How do I add in the imagesperrow = 2 I have tried below but that doesn't work so any advice you have would be terrific!

<?
$name = $row_rs_dgame['name'];
$name2 = str_replace(' ', '', $name);
$path_array['imagefileanim'] = 'images/' . $name2 . '/' . $name2 . '/moving/' . $name2 . '_Anim_1.gif';

for ($i = 1; $i <= 4; $i++)
{
$path_array['imagefile' . $i] = 'images/' . $name2 . '/' . $name2 . '/screenshots/' . $name2 . '_' . $i . '.gif';
}

foreach ($path_array as $key => $value)
{
if (file_exists($value))
{

$imagesperrow=2;
$imagesperrow=$value
echo '<img src="'.$value.'">';

} 
else 
{  
    echo 'The file ' . $value . ' does not exist<br>';  
} 

}
?>
