I looked to generate random bytes and then encode in base64 but base64 contains = + /. The below seems to do it but not sure if bin2hex can return non alpha numeric? bin2hex(openssl_random_pseudo_bytes(18)); Edited December 18, 2018 by mds1256 Jelly Bellys. So there are "recipes" of ones you can eat at the same time. The most well-known one is probably mixing a couple peanut butter jelly beans with a couple grapes. I have to say it's pretty good because they actually do taste like peanut butter and grapes, but I have one issue: the peanut butter flavor is too weak compared to the grape. Instead of a 1-1 ratio it takes more like 3-1. Weird thing, this has got to be the most famous recipe so why isn't it listed on their site? I see candy apple, tiramisu, and lemon meringue pie, but nothing about peanut butter and jelly sandwiches. Are they just not popular anymore? Personally I prefer peanut butter and chocolate (Nutella, specifically) but whatever. Which can't be that weird because Reese's is popular... Mind you peanut butter + Nutella sandwiches don't really taste like Reese's candies, but that could just be because of the type of chocolate. Like they use milk or dark chocolate while Nutella is based on hazelnut. Which reminds me, I have a jar of it in the cupboard, but it's been so long since I've used it that it might have turned into an oily mess by now. I know it's just the various oils and such separating but it looks like someone poured a teaspoon or two of water right into it and that just kinda puts me off the whole thing. Same for peanut butter for that matter except the "water" isn't clear. Dirty water. And mixing everything back together isn't so bad but it gets the knife dirty on the handle, which really bothers me because then my fingers get dirty and I have to stop what I'm doing and go wash my hands. I already do that enough each day, I don't want to make more reasons for me to do so. But beyond the oily mess there's also stuff getting stale. Stale Nutella is a pain because it's stiff and hard to deal with, and the kind of bread I like most is very soft and easily rips apart so spreading it on can be a real labor. Best method I've found is to spread a little bit on at a time but it takes so long to cover the whole face. Fine, it's a good sandwich, but in that same time I could have done something else. Maybe there's something in the freezer I could quickly heat up, or maybe there's some leftovers in the fridge I could eat. And if not there's pretty good odds that I need to go to the grocery store anyways. Ah, sorry. Forgot why I'm here.

Please can you help me with any ideas on how to get this going? Been reading so much and its all confused me too badly. Regards, Chris I have sen this function before but can not remember what it is or how to code it. It allows you remove only defined characters from the end of the string. I am not looking to replace any occurrence anywhere in the phrase, just the end. For example lets say I want to remove"ld!" from phrase "Hello World!" That function would return "Hello Wor" Thanks I have a form with some dropdownlist that get populated dynamically(depends on what the user chooses) with jquery and an xml file. In the form I have a button that takes the info and populates another form with the values of the ddl. I have coded script which populates the second form with jquery and the name of each input get dynamically added like so: Code: [Select] <input type="text" value="'+model+'" name="Model_'+model+'" id="'+model+'" readonly size="'+model.length+'" /> <input type="text" value="'+model+'" name="Model'+model+'" id="'+model+'" readonly size="'+model.length+'" />> <input type="text" value="'+color+'" name="Color'+color+'" id="'+color+'" readonly size="'+color.length+'" /> <input type="text" value="'+part+'" name="Part'+part+'" id="'+part+'" readonly size="'+part.length+'" /> <input type="text" value="$'+price+'" name="Price'+price+'" id="'+price+'" readonly size="'+price.length+'" /> <input type="text" value="'+qty+'" name="Quantity'+qty+'" id="'+qty+'" readonly size="'+qty.length+'" /> <input type="text" value="'+total+'" name="Total'+total+'" id="'+total+'" readonly size="'+total.length+'" /> What I want to do is grab the name of the element and remove the underscore and everything else form rileft to right so I am left with just the word before the underscore. I tried using substr($key,0,-28) but that wont work since everything after the underscore will have a different length. I was wondering if there is a way i can keep everything before the underscore and remove the underscore and everything after that. Thanks in advance for any input I get. Hi all!

I encountered this Crazy but cool Method below, Code: [Select] public function extra_where() { $where =& func_get_args(); $this->_extra_where = count($where) == 1 ? $where[0] : array($where[0] => $where[1]); } The only thing that made me baffled here is the underscore infront of extra_where, here below, Code: [Select] $this->_extra_where I know I already known this before, but for some reason I forgot the purpose of this underscore. Perhaps I have alzhemer's? XD Anyone familiar? This topic has been moved to mod_rewrite. http://www.phpfreaks.com/forums/index.php?topic=307587.0 |
