forcing a line-break to link to each line separately

mirandatech

I'm rather new to PHP and would need help with the following:

I have data in a field that is read and displayed as individual links (1 link per line break) on my web page.
Before displaying the links on my page, I needed to replace the underscores of their related files with slashes and so.

The links display appropriately. My problem is when I link these to each line in the field the ahref considers all the text as one big link and does not consider the line breaks as "separators".

Here's my chunk of code:

// READ EACH LINE IN FIELD AS INDIVIDUAL link

$array_chapters=explode("\r\n", $prod_chapters);
foreach($prod_chapters as $key => $value) {
if($value == "") {
unset($prod_chapters[$key]);
}
}

// REPLACE UNDERSCORES AND 'and' with SPACES AND SLASHES IN ARRAY
//to display the links appropriately

$array_chapters=str_replace(".."," ",$array_chapters);
$array_chapters=str_replace("and_","/",$array_chapters);

//DISPLAY array of LINKS and link to individual file by the same name (but with the
//underscores and such). This all works fine except that it reads each line as one
//big link

$array_chapters_lenght=sizeof($array_chapters);
$z=0;
while($z<$array_chapters_lenght){

echo '<img src="images/products/icon_purple_arrow.gif" alt="" align=right hspace=10 valign=middle>';
echo '<a href="product.php?i='.$i.'&l='.$l.'&chapter='.$prod_chapters.'">';
echo '<font color="'.${$array_chapters[$z]."_color"}.'">'.$array_chapters[$z].'</font></a><hr size=1 color=#cccccc width=170 align=left>';
$z++;
}

//Any way to get this to read (prod_chapters) as one line per link ?

Thanks for your help

$array_chapters = explode("\r\n", $prod_chapters);
foreach ($array_chapters as $value)
{
	trim($value);

if ($value == '')
{
	$value = str_replace('._.', ' ', $value);
	$value = str_replace('_and_', '/', $value);

	echo '
	<img src="images/products/icon_purple_arrow.gif" alt="" align="right" hspace="10" valign="middle">
	<a href="product.php?chapter=' . $value . '"><font color="' . $value . '_color">' . $value . '</font></a>
	<hr size="1" color="#cccccc" width="170" align="left">
	';
}
}

Thank you for your prompt response, but in replacing the original code withthe snippet you provided, nothing appeared on the page. In fact, while I can trim the underscores and such to dispplay the links correctly as such:

AES/Analog Video/Analog Audio

Machine Control/RCPs

This is what each link links to:

&chapter=AES_and_Analog Video_and_Analog AudioMachine Control_and_RCPs

As though it considers all of the content as the link and not each individual line.

perhaps the lines of $prod_chapters are separated by \n instead of \r\n? do this to check the array:

$array_chapters = explode("\r\n", $prod_chapters); 
echo '<pre>'; print_r($array_chapters); echo '</pre>';

HI, Here's the output of the script above:

Array
(
[0] => AES_and_Analog Video_and_Analog Audio
[1] => Machine Control_and_RCPs
)

I've also tried :

print_r($prod_chapters)

and this too, draws each line of data into its own line return on the page. BUT when linking to these the "A href" considers all of the content in that field as one big link.

thanks for your help,
