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...
