[SOLVED] String Question (kind of lost)

[kevinridge]

Hello,

I have confusing string question. I have a string like this (example):

 

{FILE: hello}
hello contents
{FILE: hello2}
hello2 contents

 

What im trying to do is when the code reads {FILE: *} <- it makes that file. Than it puts all the contents in the file until it finds another {FILE: *} or the end of the string.

 

I am sort of lost in the right direction to do this. Any sort of help would be great!

As your string seems to contain newline chars, explode() the string into separate lines using the newline chars.

 

Then loop through the array.

if line contains FILE: x
     close previous file (unless it's the first)
     open new file
else
     write current line to the open file
end if

close file.

Thanks for the reply but i am sort of confused how to check if it contains FILE: x and how to get the value of x out of that to use to make the file.

 

Thanks again

The following would work I suppose...

 

<?php

   $files = explode("\n",$str);
   $i = 0;
   
   foreach($files as $line) {

     if(preg_match('/\{FILE: [aA-zZ]+\}/',$line)) {
     	 preg_match('/\{FILE: ([aA-zZ]+)\}/',$line,$f);
         $file[$i][file] = $f[1].".html";	
     }
       else
       {
         $file[$i][contents] = $line; 
         $i++;
       }
   }
   
   foreach ($file as $c) {
     if($c[file] != "") {
       $handle = fopen($c[file],"w");
       fwrite($handle,$c[contents]);
       fclose($handle);
     }
   }
?>

<?php 
$str = '{FILE: hello.txt}
hello contents
{FILE: hello2.txt}
hello2 contents';

$lines = explode ("\n", $str);

$notFirst = 0;
foreach ($lines as $line)
{
    if (($p = strpos($line, 'FILE:') !== false))
    {
        $filename = trim(substr($line, $p+5), ' )');
        if ($notFirst) fclose ($fp);
        $fp = fopen ($filename, 'w');
        $notFirst = 1;
    }
    else
    {
        fwrite ($fp, $line);
    }
}
fclose ($fp); 
?>
