[SOLVED] functions.. frustrating

[spfoonnewb]

I created a function that does a lot, and I need the value of it to be inserted into a mysql database..

 

If I call the function the normal way..

 

echo function_name();

 

It returns the value that I want.

 

 

It wont let me save that value as a variable such as..

 

$var = function_name();

 

If I put the function in the mysql insert statement the output is blank.

 

VALUE('".function_name()."')

What do I do!?

 

The end result of a function has to run a for each that looks like:

 

foreach ($str as $strval) {
	echo $strval;
}

 

So I cant save the stuff the function does as variable either.

what does

<?php
var_dump(function_name());
?>

 

return ?

That returns NULL for some reason..

 

I don't understand .. like I said if I call the function by its name it returns a value..

I changed this from echo to return.. and I get one of the values.. but not all of them from the array.

 

	foreach ($str as $strval) {
	echo $strval;
}

 

	foreach ($str as $strval) {
	return $strval;
}

try something like this:

<?php

$variable = myfunction();

echo $variable;

function myfunction(){
$sum = 2 + 2;
return $sum;
}

?>

sorry didn't see your last post...

 

try something like this:

<?php

$variable = myfunction();

for($i=0, $i<=count($variable), $i++){
echo $variable[$i]."<br />";
}

function myfunction(){
foreach ($str as $strval) {
	$something[] = $strval;
}

return $something;
}

?>

Ok, now that works.. but I need a way to get it to save into the database

 

The following returns the value I need.. but I can't get it in mysql

 

$variable = myfunction();

for ($i=0; $i<=count($variable); $i++) {
echo $variable[$i];
}

 

Heres a non-working way of what I mean..

 

$variable = myfunction();
$test = for ($i=0; $i<=count($variable); $i++) { echo $variable[$i]; }

[spfoonnewb]

Any way to do that?

All you need to do is put a query in where it is echoing it now:

 

mysql_query("UPDATE your_table SET variable = ".$variable[$i]." WHERE something = 'a'");
