PHP - Convert Ascii

I have the following code:

Code: [Select]
$str = ($stringcontents[$step+38]);
$str1 = ord($str);
$bgcolor = convertchar($str1);
?>
<td bgcolor='<?php echo $bgcolor;?>'>
<span title='<?php echo $fieldname;?>' style='color: <?php echo $fgcolor;?>; font-size: 12pt'><font color="<?php echo $fgcolor;?>"><?php echo $stringcontents[$step];?></font></span>

the convertchar function takes the ord value of the ASCII chr and sets a variable for bgcolor and fgcolor using HTML color codes.  The background sets correctly, but the foreground ASCII chr is always black and does not use the font color code.

What do I need to do to get the ASCII chr to change to a color other than black?


Added:
I am using a default charset:

<META http-equiv="Content-Type" content="text/html; charset=IBM437">

Hey there,
wondering if anyone knows what this topic will be about okay lets start:

I have a search function on my site. Basically I do this:

Code: [Select]
if $_POST -> redirect ?search=$_POST

if $_GET['search'] - > sql_query($search);
Of course I am working with functions like
mysql_real_escape_string - addslashes - htmlspecialchars , but I have the following problem:

when redirecting chars like & % ? ! kill my $_GET var.

Which function solves this?

My solution:
I convert every char in $_POST into an ascii code -> redirect ?search=$ascii_codes
convert back into $string and do safe search.

Hello everyone,

I am trying to see if a term, sent from a form, is in an array that has been pulled from the database.

The problem I am having is that while the terms look the same the one from the database is using an Ascii character for a forward slash. & # 047 ;

I have tried adding the Ascii to the form value but it just rendered as a forward slash (no surprises there I suppose)

So the main reason for asking is that for all the other items in the form I can use in_array. This keeps things really tidy and easy to use.

Any ideas how I can still use in_array and get around the Ascii problem?

Cheers

Ian

Hi Coders,     any body can convert the following code into codeigniter. 

if($_GET['type'] == 'country'){
	$result = mysql_query("SELECT name FROM country where name LIKE '".strtoupper($_GET['name_startsWith'])."%'");	
	$data = array();
	while ($row = mysql_fetch_array($result)) {
		array_push($data, $row['name']);	
	}	
	echo json_encode($data);
}

Thanks

I have come across a little feature I need to create to be able to upload .doc files and convert them to .pdf using PHP.

I was wondering if anyone had any idea how I would go about achieving this, I am not asking for the code, I'm just asking on how it could be accomplished...I've searched Google and other PHP related forums but none have the answer to which I am looking for.

Any ideas or suggestions are greatly appreciated.

Regards, PaulRyan.

Hi,
  I want to place the following HTML statement inside an echo statement, i.e. in PHP I want to output an image that is also a link.
        <a href="#"><img src="Somefolder/animage.jpg" width="125" height="156" alt="some image" /></a>

  All ideas will be greatly appreciated.

I have a new project coming up, and one of the functions that this person wants is to convert word documents/pdf/html etc. to the ePub format. I've googled, but i haven't been able to find any code references for getting this accomplished...has anyone had any experience with this? Any suggestions? Any help would be appreciated! Also, I wouldn't mind an API if there even is one...

I'm having trouble with a few pages on xcart with the charsets. The problem we're having is that we need to have both utf-8 and iso type charsets as we're getting garbled code on some pages. What I can do is set the utf-8 on all pages and then encode the garbled code into utf-8. Is there a function that does this in PHP or any modules I can use? Thanks

Hello
I'm building a backend to allow a client to upload images to his site.
But my client has a lot of images in tiff format so i'd like to be able to convert tiff to jpg and only after that upload the image.
i'm using the command move_uploaded_file to upload the original image and then i'm resizing the image and creating a new one and delete the original. now i want to add to my script a way to convert the original tiff to jpeg, resize save and delete the original

here is my code that it's working fine:
Code: [Select]
if ($_FILES['foto']['name'] == "") {
    $dir = "images/spacer.gif";
} else {
$size = 124; // the thumbnail height
$filedir = 'img/ambientes/'; // the directory for the original image
$thumbdir = 'img/ambientes/'; // the directory for the thumbnail image
$prefix = 'small_'; // the prefix to be added to the original name
$maxfile = '200000';
$mode = '0666';
$userfile_name = $_FILES['foto']['name'];
$userfile_tmp = $_FILES['foto']['tmp_name'];
$userfile_size = $_FILES['foto']['size'];
$userfile_type = $_FILES['foto']['type'];
if (isset($_FILES['foto']['name']))
{
$prod_img = $filedir.$userfile_name;
$prod_img_thumb = $thumbdir.$prefix.$userfile_name;
move_uploaded_file($userfile_tmp, $prod_img);
chmod ($prod_img, octdec($mode));
$sizes = getimagesize($prod_img);
$aspect_ratio = $sizes[0]/$sizes[1];
if ($sizes[0] <= $size)
{
$new_width = $size;
$new_height = abs($new_width*$aspect_ratio);
}else{
$new_width = $size;
$new_height = abs($new_width/$aspect_ratio);
}
$destimg=ImageCreateTrueColor($new_width,$new_height) or die('Problem In Creating image');
$srcimg=ImageCreateFromJPEG($prod_img) or die('Problem In opening Source Image');
ImageCopyResampled($destimg, $srcimg, 0, 0, 0, 0, $new_width, $new_height, $sizes[0], $sizes[1]) or die('Problem In resampling');
ImageJPEG($destimg,$prod_img_thumb,90) or die('Problem In saving');
$uploadfile = $prod_img_thumb;
imagedestroy($destimg);
$fh = fopen($prod_img, 'w') or die("can't open file");
