If string too long then trim it
$MyString = strlen($MyString) > 500 ? substr($MyString,0,500) : $MyString;
$MyString = strlen($MyString) > 500 ? substr($MyString,0,497) . "..." : $MyString;
Remove last # characters
if (strlen($MyString >= 3))
$MyString_Modified = substr($MyString, 0, (strlen($MyString) - 3) );
else
$MyString_Modified = "";
Remove middle characters of a filename
//***********************************************
//***********************************************
//********** CROP FILENAME IF TOO LONG **********
//***********************************************
//***********************************************

$left = ceil($keep / 2);
$right = floor($keep / 2);
$FileName = substr($FileName, 0, $left) . "___" . substr($FileName, -$right);
}
return($FileName);

Limit URL length
//******************************************
//******************************************

//******************************************
//******************************************
//First any "https://" is removed if too long, then any arguments if still too long
