Re: [PHP] Simple HTTP request, with Range header

I imagine I would want to form a basic get header request, with URL,
whatever else I need, and a Range:bytes=1000-2000 header. If I

document I want, just bytes 1000-2000.
I hadn't heard of that option in HTTP 1.1, but that's because I haven't
looked. Interesting. Anyway, if you are certain the information will
always be at the same byte locations, then your approach will work. So,
in this case you can do something similar to the post to host scripts I
mentioned earlier this evening.
$Host = 'www.foo.com';
$Script = 'test.bin';
$Return = '';
if ($sp = fsockopen($Host, '80')) {
fputs($sp, POST $Script HTTP/1.1\n);
fputs($sp, Host: $Host\n);
/*
* THESE NEXT TWO LINES ARE FROM A POST-TO-HOST SCRIPT.
* MODIFY THEM TO FIT YOUR NEEDS, LIKE SWITCHING THEM
* TO YOUR Range: bytes=1000-2000\n HEADER.
*/
fputs($sp, Content-type: application/x-www-form-urlencoded\n);
fputs($sp, 'Content-length: ' . strlen($Post) . \n);
fputs($sp, Connection: close\n\n);
while ( !feof($sp) ) {
$Return .= fgets($sp, 2000);
}
fclose($sp);
} else {
$Return = 'pNO DICE!/p';
}
echo $Return;
If that's the approach you use, post back here with the tweaked two lines
that made it work.
BUT, if the information/byte locations may change, then you'll want to
grab the page with readfile() and then use regular expressions to find the
stuff you want to keep.
I realize it might be simpler to do a file read (assuming I'm doing this
on the very same server as the document)
You don't need to be on the same server. PHP's file reading functions are
all internet aware. http:// and ftp:// are legit.
Hope things are well for you out there in the Lone Star State,

Hmm... Where are you performing the unset()'s? Before the return, right?

Is there some way to do this [e.g., with a htaccess file]?
In an .htaccess file, you can put this

Re: [PHP] PHP: problem with patterns

Most of the time it returns 0 (zero) even though I know the session variable
is set. However, if I rename the functions.inc.php file to functions.php and
make NO changes at all to the code, it suddenly works!?
Perhaps, somewhere in your include path is another file named
functions.inc.php?
Perhpas another file you're mistakenly including has a function already
named user_acess()?
In your test script, use the function_exists() function before you define
the user_acess() function to see what's going on.

Re: [PHP] RegEx (back referencing)
On Sat, Aug 03, 2002 at 05:03:36PM +0100, Phil Ewington wrote:
Hi,
I am am writing a function to color code and indent JavaScript source using
regular expressions and cannot seem to get back referencing working.
What you're using isn't back referencing, it's utilizing substrings.
Back referencing is when you bring the substrings back into the regular
expression definition.
$string = eregi_replace((/?)(scr[^]*), «font color=maroon»\1«/font»,
$string);
Here's what your command asks PHP to do: Find any opening or
closing script tag and replace it with «font color=maroon»\1«/font».
That's not what you intend. Let's make a test script:
?php
$string = 'begin scriptjava is dumb/script end';
$string = eregi_replace((/?)(scr[^]*),
«font color=maroon»\1«/font», $string);
echo $string\n;
?
This is what comes out:
begin «font color=maroon»«/font»java is dumb«font color=maroon»«/font»
end
First off, if you want to utilize substrings, you need to use two
backslashes. \\1 instead of \1. Second, \\1 refers to the first
parenthesized part of the pattern, which in the pattern you set up is the
forward slash at the beginning of the script tag. So, let's modify the
pattern accordingly and see what happens:
$string = eregi_replace((/?)(scr[^]*),
«font color=maroon»\\1«/font», $string);
Creates:
begin «font color=maroon»«/font»java is dumb«font color=maroon»/«/font»
end
But, that's still not what you intend. I think you're really looking to
surround the scripts with maroon font tags. To do that, you need to tweak
the expression to grab the script tags, the script itself and the closing
script tag.
$string = eregi_replace('(script[^]*[^]*/script)',
'font color=maroon\\1/font', $string);
Outputs:
begin font color=maroonscriptjava is dumb/script/font end
Notice the use of ' rather than , which saves a little processor time by
not evaluaing the strings for variables.
One final improvement. Font tags are obnoxious. They cause problems for
people that choose their own background colors in their browsers. Read
http://www.analysisandsolutions.com/code/weberror.htm?ft=y for more info
on that. Anyway, I suggest using Cascading Style Sheets,
http://www.w3.org/TR/REC-CSS1, for the colroing instead:
$string = eregi_replace('(script[^]*[^]*/script)',
'code class=js\\1/code', $string);
echo stylecode.js {color: maroon;}/style\n;
echo $string\n;
Yields:
stylecode.js {color: maroon;}/style
begin code class=jsscriptjava is dumb/script/code end
Voila!

Yes. Just use empty(). It automatically checks if the variable is:
not set
null
an empty string
zero
If any of them are true, the empty() function returns true. You don't
need your function at all.

[PHP] Credit Card Validation Solution updated
Hi Folks:
I'm happy to announce the latest versions of my
Credit Card Validation Solution. This includes a new JSP Edition and
reworking the PHP and Perl Editions into an Object Oriented paradigm.
If you're using a version prior to the following, please upgrade:
Ed. Ver URI
--- ---
JSP 4.2 http://www.analysisandsolutions.com/code/ccvs-jsp.htm
Perl 4.7 http://www.analysisandsolutions.com/code/ccvs-pl.htm
PHP 4.4 http://www.analysisandsolutions.com/code/ccvs-ph.htm
An older version of it is also available for Visual Basic at
http://www.analysisandsolutions.com/code/ccvs-vb.htm
If you're not familliar with these scripts, here's a quick description:
It ensures credit card numbers are keyed in correctly. Includes checks
that the length is correct, the first four digits are within accepted
ranges, the number passes the Mod 10 Checksum and that you accept the
given type of card. Just to be clear, this process does not check with
banks or credit card companies to see if the card number given is actually
associated with a good account. It just checks to see if the number
matches the expected format.
Enjoy,

The way you posted it here, it's hard to tell which line is which.
Layout your script the same way it will look in your email, then run it.
More importantly, we need to see the error message. There are TONS of
different parse errors that can happen. Plus, I bet if you read the
message, and THINK about what it says, it'll give you a clue what to look
for.
if ((!$u_name) || (!$p_word)){
Use empty($var) rather than (!$var) to avoid warnings where the var isn't
even set.
header(Location: index.php);
Location needs a full URI: http://www.foo.com/index.php.
But, I don't think any of those will produce parse errors.

Hello,
I have this example code:

Question, is the array in memory after the function call?
So, should it be better to use this:
function doprint($a){foreach($a as $value)echo $value;}
doprint($temp=array('1','test','hello','and'));
unset($temp);
Depends on the scope you're talking about. The first way doesn't set the
array into memory outside the function, but it goes into memory inside the
function as $a. The second way puts it into memory twice, first as $temp
and second as $a.
Now, I'm not certain of what happens to your memory allocation inside the
function. I don't believe PHP automatically cleans up memory under such
circumstances. If I'm correct and you want to keep memory down, you could
do an unset() INSIDE the function.

This can be done with preg_replace() and a function. Here are some
variations on such an expression / function combo.

function alter($var) {
return _$var . '_';

$Out = preg_replace('/((div)([^]*))/i', '\\2' . alter(\\3), $Val);
# \\1 contains whole match
# \\2 contains tag type
# \\3 contains attributes
echo htmlspecialchars($Out);
echo 'hr /';
# To grab just the id attribute...
$Out = preg_replace('/((div) ?(id=(?:|\')([^\']*)(?:|\'))*)/i', '\\2'
. alter(\\4), $Val);
# \\2 contains tag type
# \\3 contains whole id attribute statement
# \\4 contains the attribute value
echo htmlspecialchars($Out);
?
Of course, be a good hacker and modify it to suit your actual needs. :)

The \s includes all white space, including line breaks. You don't need

Within a large array, would using numerical indices be quicker than associative? I'm talking about a *noticeable* difference in performance, here. The difference is marginal. The longer the variable name, the more resources used, but it's not something that you're really going to notice. More important is code readability. But, the difference between turning line wrapping on (~77 columns) in your email client will save significant time for people replying to your posts. $text = eregi_replace(([abc]+), span style=\color: red\\\1/span, $text); Would this replace any occurences of the pattern with the same pattern match in red text? I'm not sure exactly how the \\1, \\2, etc. works. It matches sub-patterns, which are the things in parentheses. The number corresponds to the parenthetical order. $text = eregi_replace((a)(b)(c), \\1, $text); Does this output only the 'a'? Exactly. --Dan -- PHP classes that make web design easier SQL Solution | Layout Solution | Form Solution sqlsolution.info | layoutsolution.info | formsolution.info T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y 4015 7 Av #4AJ, Brooklyn NY v: 718-854-0335 f: 718-854-0409 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Loading a File into Variable - How??

Yes, it IS what you need. Plus, to work around your other problems
mentioned in later posts...
$string = implode('', file('filename') );

Re: [PHP] ARRAY_PUSH with $key

I think array_push gets you cleaner lookin code (subjective). It also

AH! But your test is flawed. Reorder things so the push is first and
that'll be slower. In addition, push() is more like setting $Array[]
rather than $Array[$n].
So, here's my test, including some arithmetic calculation changes:
pre
?php
function getMicrotime() {
list($usec, $sec) = explode(' ', microtime() );
return bcadd($usec, $sec, 6);
}
# ROUND 1
$Array = array();
$start = getMicrotime();
for ($n=0;$n=1;$n++) {
$Array[$n] = $n;
}
$stop = getMicrotime();
echo 'key num: ' . (bcsub($stop, $start, 6)) . \n;
$Array = array();
$start = getMicrotime();
for ($n=0; $n=1; $n++) {
array_push($Array, $n);
}
$stop = getMicrotime();
echo 'push: ' . (bcsub($stop, $start, 6)) . \n;
$Array = array();
$start = getMicrotime();
for ($n=0; $n=1; $n++) {
$Array[] = $n;
}
$stop = getMicrotime();
echo 'key blank: ' . (bcsub($stop, $start, 6)) . \n;
# ROUND 2
$Array = array();
$start = getMicrotime();
for ($n=0;$n=1;$n++) {
$Array[$n] = $n;
}
$stop = getMicrotime();
echo 'key num: ' . (bcsub($stop, $start, 6)) . \n;
$Array = array();
$start = getMicrotime();
for ($n=0; $n=1; $n++) {
array_push($Array, $n);
}
$stop = getMicrotime();
echo 'push: ' . (bcsub($stop, $start, 6)) . \n;
$Array = array();
$start = getMicrotime();
for ($n=0; $n=1; $n++) {
$Array[] = $n;
}
$stop = getMicrotime();
echo 'key blank: ' . (bcsub($stop, $start, 6)) . \n;
?
/pre
Results...
key num: 0.000301
push: 0.000145
key blank: 0.000135
key num: 0.000136
push: 0.000135
key blank: 0.000135
The times compared to each other varied each time I reran the test.

Re: [PHP] Problem on file_exists() function

It seems that php can't detect the file in such path!!!
While this isn't your problem, it's nicer coding. Single quotes and
forward slashes:
if ( file_exists('c:/pdf_reports/dealing/test.txt') )
if (file_exists(c:\\pdf_reports\\test.txt))
Then it can detect the file is there! why?
Probably, PHP doesn't have permissions on the dealing directory or you
misspelled it.

Thank you very much for your time, but this strips the e-mail address
and lives the domain. Could you give me some hints on how to make it
working the opposite way?
Let alone, it assumes TLD's are 2-4 characters long, when in reality,
they're presently up to 6 characters long.
preg_replace('/^([a-z0-9_.=+-])+([a-z0-9-]+\.)+([a-z]{2,6})$/',
'\\1', $your_string);

Re: [PHP] Classes Constructor syntax

My question is: will this work? does PHP OOP support more than one
constructor?
No. But, here's a workaround:
class issue {
function issue($number=NULL) {
if ( is_null($number) ) {
echo 'doing the first function';
} else {
$this-issue1($number);
}
}
function issue1($number) {
echo 'in the second function';
}
}
# To call first function only...
$Obj = new issue();
echo 'hr /';
# To call second function...
$Obj = new issue('blue');
Enjoy,
