find and replace numbers

[darkfact]

I'm trying to increment a numerical value and after several hours of reading haven't come up with a solution.

this may be too much information but here it is;

 

I'm using this code to change the values in r5include.html

 

<?php $ident = $_POST['ident']; ?>
<?php
$ident2 = ($ident . 2);
$filename = 'r5include.html'; 
$string = file_get_contents($filename); 
$old = array("'images/up.jpg'","add.html' target='_blank'");
$new = array("'$ident/$ident2.jpg'","$ident.html' target='iframe2'");
$data = str_replace($old,$new,$string);
$handle = fopen($filename, "w+"); 
fwrite($handle,$data); 
fclose($handle); 
?>

 

 

but before I do that I'm copying the original to a temp file with this code:

 

<?php
$filename = 'r5include.html';
$string = file_get_contents($filename);
$tempfile = 'temp.html';
$handle = fopen($tempfile, "a"); 
fwrite($handle,$string); 
fclose($handle); 
?>

 

This is what goes to temp.html:

 

<img height=75 src='images/up.jpg' 
hidefocus='true' usemap='#record51' />
<map name='record51'>
  <area shape='rect' coords='0,0,75,75' 
href='add.html' target='_blank'>

 

I would like to increment the 2 instances of record51 to record52 and increment again each time the process is initiated.  And then  append it to r5include with this:

 

<?php
$myFile = "r5include.html";
$fh = fopen($myFile, 'a') or die("can't open file");
$filename = 'temp.html';
$string = file_get_contents($filename);
fwrite($fh,$string);
fclose($fh);
?>

 

So the question is is it possible? and if so how do I increment the record number? 

 

Thanks,

I am not exactly sure what you are trying to do..

 

My first question is what is this line doing?

$ident2 = ($ident . 2);

and what is contained in the $_POST['indent']?

 

You say you are trying to increment a numerical value but I cannot see that in your code.

$ident2 returns the value of $ident with a 2 appended to it.

 

and what is contained in the $_POST['indent']?

 

An alpha numeric value--whatever is entered in the form.

nevermind.  It was late and I was over-thinking it.  I just added to my str_replace and replace record51 with the value of $ident.  The form won't allow it if it already exists and all I needed was a unique name for each entry.  Problem solved.
