To prevent yourself with sql injection, use mysql_real_escape_string

/* Quote variable to make safe
* Added on Aug 10, 2007 */
function quote_smart($value)
{
// Stripslashes because our get_magic_quotes_gpc is on
if(get_magic_quotes_gpc()) {
$value = stripslashes(trim($value));
} else {
$value = trim($value);
}

// Replaces empty string to NULL - what is the benefit of putting NULL value?
//if($value == '') $value = 'NULL';
// Real_escape_string
$value = "'" . mysql_real_escape_string($value) . "'";
return $value;
}

/* Quote Variable to make it safe - array */
function quote_smart_arr ($arr) {
foreach( $arr as $key => $list ) {
$list = & $arr[$key]; // Re-assign the variable
$this->quote_smart($list);
unset($list); // Break the link to the object so that foreach doesn't copy the next one on top of it.
}
}

Small if/else statements - ternary operator

echo "You have $i ". ($i==1 ? "message" : "messages"). " in your mailbox.\n";

How to use references in foreach safely and sanely in PHP 4

Reference Found: July 30, 2007

There are two really really important points to remember about foreach and references:
1. foreach makes a copy
2. references (and unset!) work by directly manipulating the symbol table

In practice, this means that if you have an array of objects (or arrays) and you need to work on them *in-place* in a foreach loop, you have to do this:

foreach( $object_list as $id => $the_object ) {
$the_object = & $object_list[$id]; // Re-assign the variable to point to the real object
....
unset($the_object); // Break the link to the object so that foreach doesn't copy the next one on top of it.
}

This really works. I have used it in dozens of places. Yes, you need it all, including the unset(). You will get extremely hard-to-find bugs if you leave out the unset().

- It was in my note, but I don't know where I found them.
