Hi Martin,
Try checking for the value in $_POST['lista'] on your subscribe page.
Failing that, try the following:
print_r($_POST);
This should give you all the variables and values being sent by the form to
the page being used to process that form.
Hope this helps.
Much warmth,
Murray

Numbers with leading zeros are octal. 08 is not a valid octal number,
and is interpreted as 0.
The solution is to not use leading zeros...
echo date ("M-d-Y", mktime (0,0,0,8,7,2005)); -> Aug-07-2005

I don't think you can do a vertical centering.

Don't use double quotes if you don't want escape sequences to be expanded.
$Text = 'D:\AppServ\www\intranet\admin\store\nodirectory\sub';
$Replace = 'D:\AppServ\www\intranet\admin\store';
$with = 'http://localhost/bank/admin/store';

Replace your double quotes with single quotes... that is:
$Text = 'D:\AppServ\www\intranet\admin\store\nodirectory\sub';
$Replace = 'D:\AppServ\www\intranet\admin\store';
$with = 'http://localhost/bank/admin/store';

To elaborate on Philip's response (which is correct)...
Anything in double quotes (" ") will be interpreted by PHP before figuring out
what the actual value is. Items like \n, \t, etc are therefore converted to a
newline (\n) or a tab (\t) before assigning to the variable. Variables within
the double quotes are also evaluated before assigning. So..
$firstname = "Bob";
$lastname = "Smith";
$varname = "$firstname $lastname told me to find the file in folder
C:\newtext\";
echo $varname;
Will yield:
Bob Smith told me to find the file in folder C:
ewtext";
Actually it'll give you an error because the double quotes aren't properly
terminated.. \" is also interpreted.
Whereas..
$varname = '$firstname $lastname told me to find the file in folder
C:\newtext\';
echo $varname;
Yields..
$firstname $lastname told me to find the file in folder C:\newtext\
In this case, you have two options to get what you want:
$varname = "$firstname $lastname told me to find the file in folder
C:\\newtext\\";
..or..
$varname = $firstname . ' ' . $lastname told me to find the file in folder
C:\newtext\';
I've read "never use double quotes unless you have to" because it could
potentially speed up PHP a little because it won't be trying to interpret every
string. I'm not sure exactly how much savings this is going to give you so I
drop this in the "whatever your style dictates" category. I prefer double
quotes because I think it visually delineates the code better and I think
"$firstname $lastname" looks tidier than $firstname . ' ' . $lastname even
though I do consider it slightly looser coding practices. One's better for the
human, one's better for the machine (imo) and since I'm a human..... I think.

I once did some trials with thousand repetitions of segments of code with
different alternatives, so let me go through all of them since I have the
numbers anyway. The original was in Spanish so I'll just give the results.
The question started with using echo or print and, as the manual says, echo
is, indeed, faster:
echo "uno $f tres ": 3.04
print "uno $f tres ": 3.70
The numbers after the colons are the execution times of one against the
other for a lot of repetitions, anyhow, they should be read as relative to
one another.
Next, most people don't know that echo accepts multiple arguments separated
by commas. Separating the arguments with commas is faster.
echo 'uno ' . ' dos ' . ' tres ': 1.32
echo 'uno ' , ' dos ' , ' tres ': 0.94
In fact, this is a poor example since the difference gets larger with longer
string and more arguments. When you use dots, the interpreter has to
actually concatenate the string, looking for memory to do so and freeing it
up afterwards. This takes time. With commas, each argument is sent to the
output stream as soon as it is found, no further processing is needed in
between.
Then the single vs. double quotes:
echo 'uno ' , ' dos ' , ' tres ': 0.94
echo "uno " , " dos " , " tres ": 6.76
Once again, these are relative times but it means using double quotes is 7
times slower than single quotes
Several different alternatives with variables involved:
echo 'uno ' . $f . ' tres ': 7.38
echo 'uno ' , $f , ' tres ': 0.80
echo "uno $f tres ": 3.04
echo <<<EOT
uno $f tres
EOT: 3.29
Notice that when variables are involved, the difference in between echoing
with arguments separated with commas and separated with dots is more than 9
times faster for the commas. Using double quotes with variable expansion
is almost 4 times slower than the commas, but is still faster than
concatenating them externaly with dots. Using heredoc-style strings is not
so bad compared to double quotes.
So, if you are sending out the rule would be:
Use echo, not print. Separate arguments with commas.
Now, if you are not using echo, for example, concatenating to a variable,
the best is to use variable expansion inside double quoted or heredoc
strings. Concatenating with dots is more than twice as slow.

Use single quotes instead of double quotes:
$Text = 'D:\AppServ\www\intranet\admin\store\nodirectory\sub';
$Replace = 'D:\AppServ\www\intranet\admin\store';

I have 2 servers; one running *nix w/ PHP4, and one running Windows 2k w/
PHP5; neither of which give me read permissions to write/create text files.
Apparently, the *nix server has PHP in "Power Mode", but I'm still getting
no love from fopen, and chmod via PHP doesn't work.
Any adivce?
Code skrait from the docs:
// Let's make sure the file exists and is writable first.
if(is_writable($filename))
{
// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'w'))
{
echo("Cannot open file ($filename)<br />");
exit;
}
$somecontent = " ";
// Write $somecontent to our opened file.
if(fwrite($handle, $somecontent) === FALSE)
{
echo("Cannot write to file ($filename)<br />");
exit;
}
echo("Success, wrote ($somecontent) to file ($filename)<br />");
fclose($handle);

Hi,
I'm experiencing strange behavior when trying to run background process in
PHP.
Code :
//Run_check.php
foreach ($_POST as $kid){
`php run.php param1 param2 > /dev/null &`;
}
In this case PHP waits all the instances of the process to complete.
I don't understand why.
I have a workaround here, but anyway i don't understand why the above example
doesn't work.
If i don't run the cycle here , but run other file and there run the cycle
that runs the the background processes everything is OK.
------------------------------------
/*This file gets $_POST , implodes it , and passes the string to the other
script */
//Run_check.php
$ids=implode(',',$_POST);
` php run1.php $ids`;
------------------------------------
------------------------------------
/*This script takes the input , explodes it and runs a cycle that runs the
background process*/
//run1.php :
$kwid=explode(',',$argv[1]);
foreach ($kwid as $kid){
`php run.php param1 param 2 > /dev/null &`;
}
------------------------------------
Everything is OK.

Oh wait... you are not specifying your $_POST variable. you need to
use the key for $_POST. just do a print_r($_POST) to find the key
from the $_POST array that you are looking for. also, i would not
pass a $_POST variable directly to your shell without escaping it
somehow, first...
foreach ($_POST[$key] ...
Jordan
Did you try also sending stderr to /dev/null rather than stdout only?
I think the syntax is to add a "2>&1":
foreach ($_POST as $kid){
`php run.php param1 param2 > /dev/null 2>&1 &`;
}
This should put each process in the background and suppress all
errors and output. Does that work?

Interaction to write to a input file type is denied in browsers not to read
the value so you can can get the full path using JavaScript like any other
input in the form(document.formname.inputname.value) and pass it to other
input field lets say input fullpath using something like
document.formname.fullpath = document.formname.inputname.value <-- all using
javascript
So yes you can get the fullpath however you should redirect your question
to a JavaScript List or perhaps a javascript-php list.

I have an array of strings in which I am passing to imagettfbbox() in order
to calculate the height of the text box for each string. I am then
subtracting the height from the y position in order to deviate the pivot
point form the top left corner to the bottom left corner when I used
imagettftext() to draw the text on an image. I am giving both commands a
fontsize of 50, an angle of 0 and I am using the font ARIAL.
I am having an issue where the first string comes back with a height of 50
and the next comes back with 47. Then 50 again for the next following
string and then 47 again for the next one foloowing that. It keeps going on
and on like this and I do not understand why. I am using the same font,
font size, and angle for each string so shouldnt they all come back as the
same size?
Here's a snippet of what I am doing:
$file = "this can be any file";
$im = imagecreatefromjpeg($file);
$textcolor = imagecolorallocate($im, 0, 0, 0);
$fontfile = "arial.ttf";
$fontsize = 50;
$arr = split("CR", $_GET['text']);
$boxes = count($arr);
if (preg_match('/[0-9]/', $boxes)){
for($c=0;$c<$boxes;$c++){
$text = stripslashes($arr[$c]);
$y = $fontsize * $c;
$bbox = imagettfbbox($fontsize, 0, $fontfile, $text);
$dy = $bbox[7] - $bbox[1];
$py = $y-$dy;
imagettftext($im, $fontsize, 0, 1, $py, $textcolor, $fontfile, $text);
}
}
header("Content-type: image/jpeg");
imagejpeg($im, "" ,95);
imagedestroy($im);

Is each line of the file the same? It's going to vary depending on what
letters are in the string (ascenders and descenders for letters like
qygpi, etc.).
maybe that's it?

How do I make the text transparent over the background ?
In my web app, I want to to put a layer BEHIND the image to control the
color of the php-created text
So, the layer color in the web app shows thru the text php creates....
Would like to use alpha transparency so the color looks clean :)
how would I amend the below script to do this ?
many thanks
g
header("Content-type:".$mime); //$mime = image/png
$im = imagecreatetruecolor(200, 16); //use to draw a text box
imageAlphaBlending($im, true);
imageSaveAlpha($im, true);
$left = 5; //add a little pad to the left edge
$color = imagecolorallocate($im, 255, 255, 255);
$fontSize = 11;
// choose a font
$fontPath = "/home/siren/fonts/";
$defaultFont = "tahomabd.ttf";
$fontName = "arial.ttf";
$font = $fontPath.$fontName ;
if (! file_exists($font)) {
$font = $fontPath.$defaultFont ;
}
$text= "background color shows through the text" // Add the text
imagettftext($im, $fontSize, 0, 10, 13, $color, $font, $text);
imagepng($im);
readfile($im);
imagedestroy($im);

I have the following nested ifs:
if ($row['date'] < '2005-10-02') {
if ($row['time'] < '12:00') {
if ($row['field'] == 'P5' ) {
echo "<td class=\"tabletextbluebg\">Success";
}
}
}
else {
echo "<td class=\"tabletextred\">Failed";
}
</td>
Whenever the 3 if statements are true, I always get the correct
"Success" to echo. However, if any or all of the if statements are
false, I never get "Failed" to echo.
I know it's something simple, but I just can't see it at the moment.
TIA
