reading "<?" from a php file

[aa]

I am trying to read a.php file from another PHP file using fgets() and
display its contents. As a.php starts with <? the browser IE6 does not show
anything, although I can see all the contents in View-Source.

I tried to skip the line with <? using the following code:

@ $fp=fopen("a.ph p","r");
while (!feof($fp))
{
$line=fgets($fp );
if (!$line=="<?")
{
echo $line;
}
else
{
echo "w";
}
However it keeps outputting "w" for every line of a.php.
This does not change even is I reverse the condition to if (!$line=="<?")
as if whatever is returened by fgets($fp) cannot be compared to "<?".
I tried to add the end of the line to the pattern (!$line=="<?\n" ) or
($line=="<?\n") - same result.

What is that I am doing wrong?

Your first line, which opens the file, suppresses any error message and
you don't test for any errors.

I bet you this $ sign that if you remove the '@' you will see an error
message. Tell us what the error message is and we can help.

Hi,

I think you better use htmlentities. That function was written to display
'difficult' pieces of text into a HMTL page.
I suspect that if you just drop your <? piece and use html_entities, you get
what you are looking for.

Check this:

How about using
<?php
print htmlentities( join('', file('a.php')) );
?>

This reads the file and escapes all the HTML entities in your file and
makes the output browser-ready.

For a complete script (and as well as concrete idea), please take a
look at http://www.php.net/source.php?url=/source.php

(Source of PHP.net pages can be seen by click the view source link at
the bottom of each page... above link is the source of source.php that
does the job)

Thanks,

htmlspecialchar s() is your friend.

I tried to skip the line with <? using the following code:
Not necessary.
@ $fp=fopen("a.ph p","r");
while (!feof($fp))
No error handling? What if the file is not readable?
$line=fgets($fp );

You might also want to have a look at file() or file_get_conten ts().

Don't reinvent the wheel. Use show_source().

Thanks for offering other options.
However I would like to understand what is wrong with the one I am using?
The litaruture does not say that fgets() is not suatable for reading
characters like "<" which migh happen in any text file.

The problem is this line:
if (!$line=="<?")

You're basically saying "if $line is zero equals <?", which always fails
since $line isn't zero (nor would if equal <? if it ever was zero).

Try this instead: if ($line != "<?")

That one says "if $line isn't <?" which is exactly what you're trying to
say.

Check thr fgets function: on a newline (which is included in the return
value)

Seeing that you post TOFU style with broken quotes, I guess you are
running on the windows platform where a newline is not \n. So either
trim the read line or (better) use strpos.

FUP to comp.lang.php

Thanks, Roy, I felt I was missing something fundamental in PHP syntax.
Will you please explain how
if(!$line=="<?" )
is interpreted by PHP as
"if $line is zero equals <?" ? I.e. if(!$line= (0=="<?"))

Where zero is implied in (!$line=="<?") ?
