Information regarding SQL queries, stored with php - php

Question

So let me explain my problem, lets assume that I run query like so:
$myquery = sql_query("SELECT name FROM table WHERE name='example' LIMIT 0,1");
Now.. I want to store the retrieved name into a variable so I would do something like this:
while ($myrow = sql_fetch_assoc($myquery)) {
transfer_row($myrow);
print"Name: $row_name";
}
$stored_name = $row_name;
NOTE: transfer_row() is just a function I wrote that takes $myrow['name'] and stores it in $row_name, for easier reference
Now, all is fine at this stage, here is where it gets interesting. Note that at this stage I still have a name assigned to $row_name. Further down the page I run another query to retrieve some other information from the table, and one of the things I need to retrieve is a list of names again, so I would simply run this query:
$myquery = sql_query("SELECT name, year FROM table WHERE DESC LIMIT 0,10");
while ($myrow = sql_fetch_assoc($myquery)) {
transfer_row($myrow);
$year = $row_year;
$link = "/$year";
print "<li style=\"margin-bottom: 6px;\">$row_name\n";
}
Now, I want to write an if statement that executes something if the $row_name from this query matches the $row_name from the old query, this is why we stored the first $row_name inside the variable.
if ($row_name == $stored_name){
// execute code
}
However as most of you know, this WONT work, the reason is, it simply takes $stored_name again and puts the new $row_name into $stored_name, so therefore the value of the first $row_name is lost, now it is crucial for my application that I access the first $row_name and compare it AFTER the second query has been run, what can I do here people? if nothing can be done what is an alternative to achieving something like this.
Thanks.
EDIT, MY transfer_row() function:
function transfer_row($myrow) {
global $GLOBALS;
if(is_array($myrow)) {
foreach ($myrow as $key=>$value) {
$key=str_replace(":","",$key);
$GLOBALS["row_$key"] = $value;
}
}
}

Answer 1

Without you posting the code for the function transfer_row, we won't be able to give you an answer that exactly matches what you request, but I can give you an answer that will solve the problem at hand.
When matching to check if the names are the same, you can modify the if statement to the following.
if ($row_name == $myrow['name']){
// execute code
}
What I suggest you do though, but since I don't have the code to the transfer_row function, is to pass a second variable to that function. The second variable will be a prefix for the variable name, so you can have unique values stored and saved.

Answer 2

Refrain from using the transfor_row function in the second call so your comparison becomes:
if ($myrow['name'] == $row_name)
If you need to use this function, you could do an assignment before the second database call:
$stored_name = $row_name;
...
transfer_row($myrow);

Answer 3

In your first query you are selecting the name field WHERE name='example' , Why are you quering then? You already have what you want.
Your are querying like:
Hey? roll no 21 what is your roll no?
So perform the second query only and use the if condition as :
if ($row_name == 'example'){
// execute code
}
Does it make sense?
Update
//How about using prefix while storing the values in `$GLOBAL` ??
transfer_row($myrow, 'old_'); //for the first query
transfer_row($myrow, 'new_'); //for the second query
function transfer_row($myrow, $prefix) {
global $GLOBALS;
if(is_array($myrow)) {
foreach ($myrow as $key=>$value) {
$key=str_replace(":","",$key);
$GLOBALS["$prefix"."row_$key"] = $value;
}
}
}
//Now compare as
if ($new_row_name == $old_row_name){
// execute code
}
//You'll not need `$stored_name = $row_name;` any more
