Show Array of Images - php

Question

I'm trying to display image in 5 by 3 table.
I'm able to display the images if all empty(blank.png).
Here is the code
<?PHP
$ds ='\image';
$imagefile = array("EX_W1_01.png", "EX_W1_02.png", "EX_W2_01.png","EX_W3_01.png");
echo "<pre>"; print_r($imagefile);
$file = 'blank.png';
$d = $ds.$file;
echo "<table border = 1 width=\"540px\" cellspacing=\"0px\" cellpadding=\"0px\">";
for($row=1;$row<=5;$row++){
echo "<tr>";
for($col=1;$col<=3;$col++){
// echo"<td height=60px>W$row</td>";
//if()
echo"<td height=60px>W$row<img border = 1 height = 120 width = 120 src = $d ></td>" .PHP_EOL;
}
echo "</tr>";
}
echo "</table>";
?>
I want to display the images base on middle file name array $imagefile eg W1, W2 and if not in array, I will display the blank.png.
I was able to get the middle file name by this code, but I cannot display the images in correct row/col.
for($i=0;$i<count($imagefile); $i++) {
$wd = substr($imagefile[$i], 3, strpos($imagefile[$i], '_'));
}

Answer 1

Can you try this,
Based on your code add these when you echo the image,
$wd = substr($imagefile[$i], 3, strpos($imagefile[$i], '_'));
if($wd == *the increment either row or col*)
{
echo"<td height=60px>W$row<img border = 1 height = 120 width = 120 src = $d ></td>" .PHP_EOL;
}
else
{
echo"<td height=60px>No image</td>" .PHP_EOL;
}
See if it works.

Here it is
<?php
$ds ='/image';
$imagefile = array("EX_W1_01.png", "EX_W1_02.png", "EX_W2_01.png","EX_W3_01.png");
//echo "<pre>"; print_r($imagefile);
$default = 'blank.png';
?>
<table border = 1 width=\"540px\" cellspacing=\"0px\" cellpadding=\"0px\">
<?php
for($row=1;$row<=5;$row++){
?>
<tr>
<?php
for($col=1;$col<=3;$col++){
// construct the file name
$filename = 'EX_W' . $row . '_0' . $col . '.png';
// set the default image file
$imgPath = $ds . '/' . $default;
// in case the file name exists in your array with images,
// set the correct path to the image
if (in_array($filename, $imagefile)) {
$imgPath = $ds . '/' . $filename;
}
?>
<td height=60px>
<img border="1" height="120" width="120" src="<?php echo $imgPath; ?>"/>
</td>
<?php } ?>
</tr>
<?php
}
?>
</table>
As you can see I also prefer to "embed" the php code in the HTML. It makes no sense to me outputting HTML code through the PHP engine if it can be parsed as is ;-)
