Use arrays.

<pre><code>$div[$i] = $p1[0];
</code></pre>

And through the page you can:

<pre><code>echo $div[1];
blah blah blah
echo $div[2];
blah blah blah
echo $div[3];
etc etc
</code></pre>

If you want to keep your structure structure then use:

<pre><code>$tempname = "div_".$i;
$$tempname=$p1[0];
</code></pre>

organize it in arrays like this:

$results = array();

while ($p1 = mysql_fetch_array($home_p1)){
 //$div_.$i = $p1[0];
 $results[] = $p1[0];
 $i++;

then you can access the first line by

<pre><code>echo $results[0]; // second by $results[1] and so on.
</code></pre>

have fun!

blocks|key|943650|text|您不能像这样创建变量：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|943651|$div_.$i+=+$p1[0];|code-block|syntax|javascript|943652|您应该像这样将它们放入一个数组中：|943653|$div_array+=+array();|943654|然后|943655|$div_array[$i]+=+$p1[0];|943656|现在您可以通过直接引用数组来输出它们：|943657|echo+$div_array[1];|943658|或者，您可以使用extract将数组扩展为变量：|943659|extract($div_array,+EXTR_PREFIX_ALL,+'div_');|943660|现在，您有了$div_$i变量。|943661|entityMap^0|0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|11|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|12|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|13|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|14|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|15|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|16|8|@]|9|@]|A|$]]|$1|Q|3|R|5|D|7|17|8|@]|9|@]|A|$E|F]]|$1|S|3|T|5|6|7|18|8|@]|9|@]|A|$]]|$1|U|3|V|5|D|7|19|8|@]|9|@]|A|$E|F]]|$1|W|3|X|5|6|7|1A|8|@]|9|@]|A|$]]|$1|Y|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|Z|$]]

You can't create variables like this:

<pre><code>$div_.$i = $p1[0];
</code></pre>

You should put them into an array like this:

<pre><code>$div_array = array();
</code></pre>

then

<pre><code>$div_array[$i] = $p1[0];
</code></pre>

Now you can output them by referencing the array directly:

<pre><code>echo $div_array[1];
</code></pre>

Or else you can expand the array into variables using extract:

<pre><code>extract($div_array, EXTR_PREFIX_ALL, 'div_');
</code></pre>

Now you have your $div_$i variables.

blocks|key|4981104|text|为了理解你正在尝试的东西，你应该像下面这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4981105|$home_p1+=+mysql_query("select+div_content+from+page_content+where+(page_id+=+'1');",$db);

$i=1;

$i=1;
$divs+=+Array();
while+($p1+=+mysql_fetch_array($home_p1)){

In order to accopmlish what you are trying to, you should do something like next:

<pre><code>$home_p1 = mysql_query("select div_content from page_content where (page_id = '1');",$db);

$i=1;
while ($p1 = mysql_fetch_array($home_p1)){
 $name = 'div_' . $i;
 $$name = $p1[0];
 $i++;
}
</code></pre>

You will get the list of variables with names $div_1, $div_2, etc.
<a href="http://www.php.net/manual/en/language.variables.variable.php" rel="nofollow">http://www.php.net/manual/en/language.variables.variable.php</a>

But the best way, as it was said, to use arrays.

<pre><code>$home_p1 = mysql_query("select div_content from page_content where (page_id = '1');",$db);

$i=1;
$divs = Array();
while ($p1 = mysql_fetch_array($home_p1)){
 $divs['div_' . $i] = $p1[0];
 $i++;
}
</code></pre>

I have a MySQL table which contains page content, each line of content has a page_id number

I want to load all the variables for the page I'm on, then display them where they need to be...

I'm naming the variables: div_1, div_2, div_3 etc etc

here's what I'm trying:

PHP

<pre><code>$home_p1 = mysql_query("select div_content from page_content where (page_id = '1');",$db);

$i=1;
while ($p1 = mysql_fetch_array($home_p1)){
$div_.$i = $p1[0];
$i++;
}
</code></pre>

then throughout the page i can

<pre><code>echo $div_1;
blah blah blah
echo $div_2
blah blah blah
echo $div_3
etc etc
</code></pre>

But I'm getting nothing back, I'm not even sure if this is the correct logic to do such a thing?
