Array/Foreach assistance with database query

Last Modified: 2013-12-13
I am wondering if there is a much more simpler way to pull info from a database and assign a variable to it and use that variable to echo info. What I have snipped works, im just tired of typing each field each time I create a new database.... I want to keep from having to type all the database fields.
Is this possible?
$query=" SELECT * FROM vendor WHERE id='{$_POST['id']}'";
 

$result=mysql_query($query);

$num=mysql_numrows($result);
 

$i=0;

while ($i < $num) {
 

$busniessname=mysql_result($result,$i,"businessname");

$primaryphoneareacode=mysql_result($result,$i,"primaryphoneareacode");

$primaryphoneprefix=mysql_result($result,$i,"primaryphoneprefix");

$primaryphonenumber=mysql_result($result,$i,"primaryphonenumber");

$ext=mysql_result($result,$i,"ext");

$street1=mysql_result($result,$i,"street1");

$street2=mysql_result($result,$i,"street2");

$primaryfaxareacode=mysql_result($result,$i,"primaryfaxareacode");

$primaryfaxprefix=mysql_result($result,$i,"primaryfaxprefix");

$primaryfaxnumber=mysql_result($result,$i,"primaryfaxnumber");

$primarycontact=mysql_result($result,$i,"primarycontact");

$primarycontactemail=mysql_result($result,$i,"primarycontactemail");

$city=mysql_result($result,$i,"city");

$estimatingcontact=mysql_result($result,$i,"estimatingcontact");

$estimatingcontactemail=mysql_result($result,$i,"estimatingcontactemail");

$state=mysql_result($result,$i,"state");

$ownerofficercontact=mysql_result($result,$i,"ownerofficercontact");

$ownerofficercontactemail=mysql_result($result,$i,"ownerofficercontactemail");

$zip=mysql_result($result,$i,"zip");

$=mysql_result($result,$i,"estimatingcontact");

$estimatingcontactemail=mysql_result($result,$i,"estimatingcontactemail");
 

++$i;

I think you are looking for extract() function:
http://lu.php.net/manual/en/function.extract.php

$query=" SELECT * FROM vendor WHERE id='{$_POST['id']}'";
 
$result=mysql_query($query); 
while ($row = mysql_fetch_assoc())
{
  extract($row);   
  // do something here...
} 
?>

As you only retrieve one row you just can use:
$query=" SELECT * FROM goodco WHERE id='{$_POST['id']}'";

$result=mysql_query($query);

$num=mysql_numrows($result);

 

$row = mysql_fetch_assoc($result);

extract($row);

yes, you would specify $job, $commitment etc.
extract(array("job" => "Engineer, "commitment" => "full"));
will result in the variables $job and $commitment to be created and filled.
the mysql_fetch_assoc() will return an array of the field values with the field names...
