str_replace(replacewhat, withwhat, infield)
strlen(field)
STRPOS:
strpos(inwhat, findwhat)
NOTE: this returns a 0 if it is the first character, not a 1.
You typically have to use a complex formula to check for null values:
if (strpos($row['Departments'],"Photo") !== false and strpos($row['Departments'],"Photo")>=0)
{
echo " checked ";
}
The reason you have to be careful is because doing a strpos(inwhat,findwhat)>=0 doesn't work, because if it doesn't find the value, it returns a 0, but if that value is in position 1 of the string, it also returns a zero.
Another way of doing it:
if (stripos($mynote, "sq")>0 or stripos($mynote,"sq")===0 )
TO make a folder:
$myfolder=$_SERVER['DOCUMENT_ROOT']."/uploads/James/";
if (!file_exists($myfolder)) {
mkdir($myfolder, 0777, true);
}
Referencing file locations:
include $_SERVER['DOCUMENT_ROOT']."/uploads/orderid.php";
