RE: [PHP] Problems w/ goto
Ethan,
I tried to test your code, but I get this error next to the labels and goto
statements:
Language feature not compatible with PHP version indicated in project
settings
I have PHP 5.3.0.

Dear List -
Thank you with your excellent help in the past. Here is another puzzler
I am trying to write a program that can have two(2) independent forms
in one PHP file. When I run the code below [from PHP - A Beginner's
Guide], to which I have added a second form, it freezes. Without the
goto statements, it runs. When it does run, it displays both forms
on one Web screen. What I desire is for the first form to be
displayed, the data entered and then the second form displayed. In
an actual, not test program like this one, the data in the second
form would be dependent on the first form.
What did I do wrong?
Thanks in advance.
Here is the code:
http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
Project 4-4: Age Calculator
Project 4-4: Age Calculator
";
echo " Enter your date of birth, in mm/dd/ format: ";
echo " ";
echo " ";
echo " ";
echo " ";
goto begin;
// if form submitted
// process form input
}
else
{
starter:
if (isset($_POST['cat']))
goto purr;
// split date value into components
$dateArr = explode('/', $_POST['dob']);
// calculate timestamp corresponding to date value
$dateTs = strtotime($_POST['dob']);
// calculate timestamp corresponding to 'today'
$now = strtotime('today');
// check that the value entered is in the correct format
if (sizeof($dateArr) != 3) {
die('ERROR: Please enter a valid date of birth');
}
// check that the value entered is a valid date
if (!checkdate($dateArr[0], $dateArr[1], $dateArr[2])) {
die('ERROR: Please enter a valid date of birth');
}
// check that the date entered is earlier than 'today'
if ($dateTs >= $now) {
die('ERROR: Please enter a date of birth earlier than today');
}
// calculate difference between date of birth and today in days
// convert to years
// convert remaining days to months
// print output
$ageDays = floor(($now - $dateTs) / 86400);
$ageYears = floor($ageDays / 365);
$ageMonths = floor(($ageDays - ($ageYears * 365)) / 30);
echo "You are approximately $ageYears years and $ageMonths months
old.";
goto meow;
}
meow:
if (!isset($_POST['dob']))
goto begin;
if (!isset($_POST['cat']))
{
echo " ";
echo " Enter your kitten's name: ";
echo " ";
echo " ";
echo " ";
echo "";
}
else
{
purr:
$name_cat = $_POST['cat'];
echo "Your Kitten is $name_cat";
$ender = 1;
}
if ($ender == 0)
goto begin;
first_step:
?>

[PHP] Hot to replace words with preg_replace without duplicates
Hi there,
I want to create a function which will replace certain words out of a
text with internal links. That works so far, but if I have two matches,
I end up with invalid html code.
Example:
Welpen /hunde
Chihuahua Welpen/hunde,chihuahua
function seo_internal_links($str, $links, $limit) {
foreach($links AS $link){
$pattern[$k] = "~\b($link[phrase])\b~i";
$replace[$k] = '\\1';
$k++;
}
return preg_replace($pattern,$replace,$str, $limit);
}
seo_internal_links($ad[text], $seo_internal_links, $limit = 1);
This will result in:
Chihuahua Welpen
Has somebody an idea on how to avoid this? I would also like to limit
the amount of hits, but the limit in preg_replace accounts only for
unique words, not the whole array.
Thank you for any hint,
Merlin

Re: [PHP] HTML id attribute and arrays
What are you trying to accomplish?
What do you think it wrong with the code below?
On 12/17/2010 8:19 AM, Martin C wrote:
Hi,
PHP converts x[a]=b parameter of the HTTP request as an array named x
with its item named a set to value b. So, it seems possible to have the
following (X)HTML code:
Unfortunatelly, HTML specification does not allow neither "[" nor "]"
inside the id attribute. Specifically:
* Must begin with a letter A-Z or a-z
* Can be followed by: letters (A-Za-z), digits (0-9), hyphens ("-"),
underscores ("_"), colons (":"), and periods (".")
* Values are case-sensitive
How should I follow the HTML specification while having the passed
parameters automatically converted to arrays in PHP?
Thank you for any tips,
Martin

As a 'professional' programmer, working for an entity, we deal with
these problems as we go. As novices, we deal with it on a daily
basis. As computer scientists, we think of it as a problem already
solved, but in need of translation. Understand, buddy pal.

Hello all!
I have a question regarding arrays and the way I can use a value.
Let's say I have this string:
$s = 'banana,apple,mellon,grape,nut,orange'
I want to explode it, and get the third value. For this I would normally do:
$a = explode(',', $s);
echo $s[2];
That's all fine, but is there a way to get the value directly, without
having to write another line in my script. I mean something like this:
echo explode(',', $s)[2];
or
echo {explode(',', $s)}[2];
I couldn't find out this answer anywhere, that's why I posted here.
Cheers and thanks!
Sure it CAN be done. Nobody laugh too loud here... But...
Outputs: grape
The {3} part is equivalent to the array position. Change that number,
and you change which word will get displayed.

[PHP] PHPmailer.. best way to send to many recipients?
Hi everyone,
I just started using PHPmailer for one project that requires SMTP
authentication (if I said that right).. and all is well.. but I want
to ask now before it might get outta hand later:
How many comma-delim'ed addresses can I stuff in $BCC_recipients
before I have problems (need to restructure the design)?
--
require("php_inc/class.phpmailer.php");
$mail = new PHPMailer();
$BCC_recipients = "x...@host.com,y...@server.com"; // <---just an
example
$arrBCC_recipients = explode(",", $BCC_recipients);
foreach ($arrBCC_recipients as $email2stuffInBCC) {
$mail->AddBcc($email2stuffInBCC);
}
if(!$mail->Send()) { // problem
--
For now there will be less than 100 Bcc recipients.. but later, more.
I don't know if/when it will ever grow past 1,000.

[PHP] goto - My comments
Dear List -
Thanks to all for your EXCELLENT comments. I definitly agree that
goto is a command to be avoided at all costs. In this case, I could
not figure out how to acheive the desired result without the
goto. So being a newbie, I humbly request that you show [and at
the same time teach] me how to rewrite the code to eleiminate the goto.
Additionally, would you please do the same for the code I list
below. This code runs perfectly.

This is the form:
Data Search
Data Search
Site:
Record Number:
First Name:
Last Name:

Male
Female

I would have thought school would have been out on account of Christmas and all.
In any event, here's my rewrite:
switch (true)
{
case isset($_POST['Site']) && trim($_POST['Site']) != '':
$sql1 = $sql1 . "site = '$ste'";
break;
case isset($_POST['MedRec'])&& trim($_POST['MedRe']) != '':
$sql1 = $sql1 . "MedRec = '$req'";
break;
// ...
default:
if(isset($_Request['Sex'])&& trim($_POST['Sex']) != '' )
{
if ($_REQUEST["Sex"] == "0")
$sex = 'Male';
else
$sex = 'Female';
$sql1 = $sql1 . " = '$sex'";
$sexdone = 1;
}
if(isset($_POST['Hx'])&& trim($_POST['Hx']) != '')
{
$sql1 = $sql1 . "Hx = '$hx'";
$done = 1;
}
}
You could also do an if / else if / else if / ... / else.
