Why doesnt this work? I need it to start out at 1 instead of 0. And if I change $i to = 1 then it doesnt grab the first row.

<?php
if(isset($_POST['question'])) {
for ($i=0; $i<count($_POST['question']);$i++) {
$question=$_POST['question'][$i]."<br />"; echo "<b>Question $i:</b> $question";
}
}
?>
EDIT: Instead of starting out at 1.. I just need it to echo starting with "Question 1:" instead of "Question 0:".
All array keys, by default, begin at index 0 (unless explicitly stated), therefore starting at 1 will not include the first result.
If you need posted data started with 1 (which is pointless actually) you have to change your html from
<input type="text" name="question[]" class="text">
to
<input type="text" name="question[1]" class="text">
etc
If all you want to do is output each question (without any validation!) you don't need the question variable at all. Just do:
echo 'Question #' . ($i + 1) . ': ' . $_POST['question'][$i];
It's seem like you would like to get output
<b>Question 1:</b> Blah Blah
But. The array key is start from 0 by default
There have 2 way to get it. If you really want an array start with key number 1 . you can do by following code.
$new_array = array();
for ($i=0; $i<count($_POST['question']);$i++) {
$new_array[$i+1] = $_POST['question'][$i];
}
but if you want to have just 1. you can do like
if(isset($_POST['question'])) {
for ($i=0; $i<count($_POST['question']);$i++) {
$question=$_POST['question'][$i]."<br />"; echo "<b>Question ".$i+1.":</b> $question";
}
}
Hope it's helpful.
Parse error: syntax error, unexpected '"', expecting ',' or ';' in /home/organik/public_html/beta/test.php on line 238$question=$_POST['question'][$i]."<br />"; echo "<b>Question ".$i+1.":</b> $question";
if(isset($_POST['question'])) { foreach (($_POST['question']) as $key=>$value) { $key +=1; echo "<b>Question ".$key.":</b> $value"; } }$question_no = $i + 1; $question=$_POST['question'][$i]."<br />"; echo "<b>Question $question_no :</b> $question"; hope it's workFor all the answers here.. and i'm sure they know it.. for logical and simple reason, start your array at zero. Because.. like Russel Dias says: all array start at 0. If you don't want to make it complicated, start it at 0.
A high recommandation of all programmers :D Good Luck!
$i Like : echo "<b>Question".$i+1.":</b>"
$i + 1or, alternatively initialize another variable to keep count of the questions ?
