print or printf

Anon

Hi there!

I have problem!

Why doesn't the following work?

...
for($ques=1; $ques <= $totalques; $ques++){
print "<tr><td>question number$ques:</td>";
print "<td>$question$s</td></tr>";
}
....

I get totalques from parameters and it works fine. QUESTION$ques also works fine. But when I try to print $question$ques it prints only nubers 1,2,3 (if totalques is 3).

I get $question1, $question2, ..., $question25 also from parameters

What can I do??

It works just fine, but it probably does not do what you think it will do.

What do you want it to do?
Make sure that all the variables contain the correct values!

you speak of printing $question$ques, but your script only contains a $question$s.

I wrote it wrong. Here is the right version:
...
for($ques=1; $ques <= $totalques; $ques++){
print "<tr><td>question number$ques:</td>";
print "<td>$question$ques</td></tr>";
}
....

At previous page you can add some questions and this page displays what you have added. Row print "<td>$question$ques</td></tr>"; should print the questions what you have added.

At previous page is <input type=text name=question1>,<input type=text name=question2>,<input type=text name=question3> and so on.

And little more:

Original version:
...
for($ques=1; $ques <= $totalques; $ques++){
print "<tr><td>question number$ques:</td>";
print "<td>$question$ques</td></tr>";
}
....

if i change it like this ($question$ques => $question1)
...
for($ques=1; $ques <= $totalques; $ques++){
print "<tr><td>question number$ques:</td>";
print "<td>$question1</td></tr>";
}

Now it prints only the text what is inside at the question1.'

Try something like this:

print "<TD>".$question." ".$ques."</TD>";

I'd recommend changing your vars to an array, like this:
<input type=text name=question[0]>,<input type=text name=question[1]> etc.
Then the last line in your for loop would say

print "<td>$question[$ques-1]</td></tr>"

Or you could leave the vars the way they are and use a variable variable, e.g.
$current_question = "question".$ques;
print '<td>'.$$current_question.'</td></tr>';

Nope!

It prints only the value from $ques

Hi,

Playing with variable variable is not easy huh ?

maybe this sample code will help:

<?php

    $var1 = "aaaa";
    $var2 = "bbbb";
    $var3 = "cccc";
    $var4 = "dddd";

    for( $i=1; $i<5 ;$i++){

// Don't surround var name with quotes
echo ${"var".$i}."<br>\n";
}

This will return the values of the variables named var$i where $i=[1..4]

Thank you very much!!!!

I change my vars to an array like you say! Now it works!! Thank you!!
