Stripping It To The Bone - PHP

Now that you know the basics of reading and writing files, this second segment of our tutorial on the PHP filesystem API takes you into deeper waters, showing you how to copy, delete and rename files; scan directories; work with uploaded files over HTTP; perform pattern matches on file names; and read and write to processes instead of files.

You may remember, from the first part of this article, how I used the
fgets() function to read the contents of a file and print it to the browser. In case you don't, here's a quick reminder:


<?php

// set file to read
$filename = "mindspace.txt";

// open file
$fh = fopen ($filename, "r") or die("Could not open file");

// read file
while (!feof($fh))
{
$data = fgets($fh);
echo $data;
}

// close file
fclose ($fh);

echo "-- ALL DONE --";

?>

PHP also offers the fgetss() function, which works just like the regular
fgets() function, except that it also strips out HTML and PHP code from the lines it reads. So, for example, if you had a file containing intermingled HTML code and ASCII text (as most HTML files are), like in the following example,


<HTML>
<HEAD>
</HEAD>

<BODY>

<TABLE BORDER="0" CELLSPACING="0" CELLPADDING="0">
<TR>
<TD>
<FONT FACE="Verdana, Arial" SIZE="2" COLOR="#66CC00">
<B><A HREF="article.php?id=169"><IMG SRC="/images/sm_arrow.jpg" WIDTH=20 HEIGHT=20 ALT="" BORDER=0 ALIGN="ABSMIDDLE" HSPACE=4>Learning To SMILe</A></B> </FONT> </TD> </TR> <TR> <TD> <FONT FACE="Verdana, Arial" SIZE="1" COLOR="Black">

</FONT>
</TD>
</TR>
</TABLE>

</BODY>
</HTML>

you could retrieve just the ASCII from it with the following example script:


<?php

// set file to read
$filename = "data.html";

// open file
$fh = fopen ($filename, "r") or die("Could not open file");

// read file
while (!feof($fh))
{
// strip out tags
$data = fgetss($fh, 999);

// if nothing present after stripping tags, move on
// else print the cleaned line
if (trim($data) != "")
{
echo trim($data) . "\r\n";
}
}

// close file
fclose ($fh);

echo "-- ALL DONE --";

?>

Here's what the output looks like:
