PHP - Using Implode() In Array To String Conversions
This is my code for displaying images from a folder:
function generate_img ($imagepointer, $imageornot){
if($imageornot == 1){ $var = getcwd(); $dirlocation = $var."\\imageuploads\\".$imagepointer; $files = array_diff(scandir($dirlocation), array('..', '.')); foreach ($files as $image){ $data[] = array('label' => '<img src="/imageuploads/'.$imagepointer.'/'.$image.'" alt="thumbnail"> <br/>'); }; return $data; } else { return FALSE; } } I'm using it with print_r: <p><?php print_r(generate_img($imagepointer, $imageornot)); ?></p> Working ok, but obviously not good for a live site. Is implode() a good idea in this situation? And how would I use it? Appreciated. Similar TutorialsCode: [Select] while($row=mysql_fetch_assoc($query)) { $id = $row['id']; $col1 = $row['name1']; $col2= $row['name2']; $col3= $row['name3']; ${"$id"} = array("$col1","$col2","$col3"); ${"$s".$i}[] = ${"$id"}; } This is just a brief example of what i'm trying to accomplish,$i is incremented somewhere else. I'm trying to implode the arrays in the array. So below i have imploded the main array but how do i implode the other arrays? Code: [Select] for($i=0;$i<11;$i++) { $array = ${"s" . $i}; $outcomes = implode("",$array); //implodes main array } I came accross a problem where im not sure how to add the word "and" inbetween my variables. I'm only displaying one $field below but i have 6 of them. If I add and as the seperator in the implode it will repeat it and and. Also it will put it at the end Code: [Select] <?php $field1 = "Farms to " . $_POST['farms_population']; $a = array("$field1", "$field2", "$field3", "$field4", "$field5", "$field6"); $_SESSION['changed'] = "You have changed " . implode(" ",$a); echo $_SESSION['changed']; ?> wanting it to echo something like You have changed Farms to 30 and Larva Pools to 10 and Homes to 10 This topic has been moved to Third Party PHP Scripts. http://www.phpfreaks.com/forums/index.php?topic=319071.0 I get this error on my homepage : Warning: implode() [function.implode]: Invalid arguments passed in /home/shqip1/peqini.com/wp-content/themes/sportpress/functions/wpzoom-widgets.php on line 1469 This is the code to modify http://pastebin.com/RiBsyG3c Thanks This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=308349.0 I am getting this error in the header.php of my wordpress theme...

Can anyone help me complete this script I can get it working with using an implode function, but for the purpose of knowledge I want to not use it. I just want it to echo back the corresponding checkboxes, but I can't get the echoing correct, it echoes back array not the value? Code: [Select] <html> <title>What do you want on your Tombstone?</title> <body> <?php $Output_form = true; if (isset($_POST['submit'])) { if (empty($_POST['toppings'])) { echo '<b>You forgot the toppings for your Tombstone.</b>'; echo '<br>'; echo '<br>'; } else { echo '<p><b>This is what you are getting on your Tombstone: '; (array)$_POST['toppings']; echo $toppings; echo '!'; echo '</p></b>'; $Output_form = false; } } if ($Output_form) { ?> <form action="ProcessToppings.php" method="post"> <p><i><h2>What do you want on your Tombstone?</h2></i></p> <p> <input type="checkbox" name="toppings[]" value="pepperoni" /> Pepperoni<br /> <input type="checkbox" name="toppings[]" value="sausage" /> Sausage<br /> <input type="checkbox" name="toppings[]" value="mushrooms" /> Mushrooms<br /> <input type="checkbox" name="toppings[]" value="cheese" /> Cheese<br /> <input type="checkbox" name="toppings[]" value="olives" /> Olives</p> <p> <input type="submit" value="Make that Peet-Za!" name="submit" /></p> </form> <?php } ?> </body> </html> Hi, I am a little bit new to php, and I am learning about array functions. I just wanted to know the difference between implode and explode in arrays, and how each of them would be used? Thank you! I have a script that takes a 2 or 3 page pdf, uploads it and hashes the file name to something that isn't guessable. We now want to add an image of each of the PDF for users who don't have Adobe Reader. Some pdf's will be 2 and some 3 pages. Should I: A) Let convert name the different pages "*-0.jpg, *-1.jpg..." and then use a recursion function (it's already written for another reason) to crawl the folder, B) Use a PHP/PDF library to determine the number of pages, then add the value to the database's corresponding row. C) Use a hybrid of both D) Any better ideas??? Thanks Let's say there is an application where a user would like to use English and Metric systems to enter values. For example, to handle customer orders where customers give data in this or that system, (but not both).
From the user-view, all the user cares about is if they can select English or Metric system, enter their values, click submit, and have their data added to the page in their choice of system, and have their values (and choice of system) stay the same.
The back end however is set up to do "compute" operations with English system in mind only. So inside back end, before the compute module, all the values should be converted to English. Some things like precomputed constants, that exist in computations are in English unit of measurements.
So I have attached an image of what I am thinking ..
* first (top) way is one where the front-end takes care of conversions. Back-end is not aware of another system (which makes it difficult sometimes, when trying to display a page back to the user saying "We know you chose system X"), and being aware of chosen system is something that I think is beneficial.
* the second (bottom) way is where front end is merely a passing device to back end, and bac-end takes care of conversions. Back-end is also aware of the two systems
My question is -- is there a preferred way to design an application when it comes to considerations above? Have a system-aware back-end, or try to localize system to front end only?

How can I take a string full of comma separated hex values such as : <?php $myStr = ( "00ffff", "00cccc", "009999", "007777", "004444", "001111", "01ffff", "01cccc", "019999" ); ?> & turn it into 3 separated arrays like : <?php $myNewArrs = [ Array1 ( 3 ), Array2 ( 3 ), Array3 ( 3 ), ]; ?> which REALLY looks like :
<?php
$myNewArrs = [
Array ( "00ffff", "00cccc", "009999" ),
Array ( "007777", "004444", "001111" ),
Array ( "01ffff", "01cccc", "019999" ),
];
?>
? Thank you & have a great afternoon!
Edited May 27 by AquariaXI OK so here is what I want to do. I have a bunch of strings stored in a table. The strings are like this grandparent.parent.child. some are just parent.child What I want to do is Select all and then put them into an array. soooo x.y.z would become $Var['x']['y']['z'] and a.b would become $Var['a']['b'] It has to be dynamic because some strings are just 2 levels, and it goes all the way up to 6 levels. I have different plans for setting the variably to something but I can handle that. Any ideas? Hi I need to know how to arrange this thing looking something like an array to be able to find values from it. The problem is, I don't really even know what I am dealing with here. Wonder if you could help me out. I have the following mess stored in a $messages variable: {"messages":[{"message_id":2314446,"from":"441234568790","timestamp":1280703181,"text":"first text"},{"message_id":2315147,"from":"123456789014","timestamp":1280755014,"text":"another text"}],"unread":0} and I don't know how to do the following: I need is to get only the message text from any message that matches my wanted phone number. For example: I want to get the text value from message which from is 123456789014. /Henry Hi all, Im so stuck on this! Cant figure out a solution... $precip_array[0] has a value of "80" in it as a string. I need to compare it to an integer. echo (int)$precip_array[0] returns a "0". Ive also tried adding a 0 but that results in the same. I did a var_dump on $precip_array[0] which returns string(17) "80" I think 17 signifies the length of the string, but I only see 2 digits when I echo this. Any help is much appreciated. If I wanted to print a string that contains a variable that also contains an array, how would I do so? I want to put the resulting echo into a log file. Example: “These are the books: $userArray and these are the pages: $pagesArray”; With just an array, I can use print_r($array, true) to get an array formatted for use in a string (which works well for my purposes) but this doesn’t work with two arrays unless I do this manually. (Such as setting the $user_array = print_r($userArray). But I want to write a function that will take a string, potentially containing arrays (as variables), and interpolate/make them legible for humans. (Some of the arrays are also multidimensional.) But it looks like I can't even concatenate a string and an array. $string = $string . $array. gives an error, array to string conversion. I don’t understand PHP very well so please explain what is going on here. and the best way to record something like the Example above. |
