Simpale PHP and HTML coding

Thanks, so I ended up with this code: <?php # A collection of functions that will be included in Greeting_tree.php function html_begin ($title, $header) { print ("<HTML>\n"); print ("<HEAD>\n"); if ($title) print ("<TITLE>$title</TITLE>\n"); print ("</HEAD>\n"); if ($header) print ("<H2>$header</H2>\n"); } function html_end () { print ("</BODY></HTML>\n"); } { function str_split($string, $length = 1) { $return = array(); $count = 0; for($i = 0; $i < strlen($string); $i++) { if($i % $length == 0) { $count++; continue; } $return[$count] .= $string{$i}; } return $return; } } function GenerateTree($size) { $tree = ""; if ($size < 9 || $size > 17) $size = 9; for ($x = 0; $x < $size; $x++) { $spacer = str_repeat("0", ($size - $x)); $stars = str_repeat("*", ($x*2)+1); $tree .= $spacer . $stars . $spacer . "\n"; } $spacer = str_repeat("0", ceil($size/2)-1); $tree .= $spacer . "*" . $spacer . "\n"; $tree .= $spacer . "*" . $spacer . "\n"; $tree .= $spacer . "*" . $spacer . "\n"; return $tree; } function DisplayChar ($type, $char) //display leave color when $char = "*" and background color when $char = "0" //according to the tree type { $colors = array("red", "gold"); if ($type === "Holiday") $colors = array("red", "green"); if ($type === "SacState") $colors = array("gold", "green"); //if ($type === "surprise") if ($char != 0 && $char != "*") return $char; if ($char == 0) return '0'; if ($char == '*') return '*'; } //find DisplayChar function body outline from PHP notes in SacCT and put the completed version here if($type=="Holiday") { if($char=="0") {echo("$char");} else {echo("$char");}; } else if($type=="SacState") { if($char=="0") {echo("$char");} else {echo("$char");}; } else if($type=="Surprise") { if($char=="0") {echo("$char");} else {echo("$char");}; } //display greeting of the given tree type function DisplayGreeting($type, $size = 9) { $tree = GenerateTree($size); $coloredTree = ""; foreach (str_split($tree) as $char) { $coloredTree .= DisplayChar($type, $char); } return $coloredTree; } //find DisplayGreeting function body from PHP notes in SacCT and put it here { If($type=="Holiday") { $message="Happy Holidays!!!"; } else if($type=="SacState") { $message="Go Sac Hornets!!!"; } else if($type=="Surprise") { $message="Cake is a lie!!"; } echo("$message "); } ?> I still cant get the tree or the message to show up. This is my website for it: http://athena.ecs.csus.edu/~cs010415/Greeting_tree.php This is how it should be: http://athena.ecs.csus.edu/~cs010134/Greeting_tree.php Any suggestions?

So I worked on the functions a little more and this is what I got: <?php # A collection of functions that will be included in Greeting_tree.php function html_begin ($title, $header) { print ("<HTML>\n"); print ("<HEAD>\n"); if ($title) print ("<TITLE>$title</TITLE>\n"); print ("</HEAD>\n"); if ($header) print ("<H2>$header</H2>\n"); } function html_end () { print ("</BODY></HTML>\n"); } function GenerateTree($size) { $tree = ""; if ($size < 9 || $size > 17) $size = 9; for ($x = 0; $x < $size; $x++) { $spacer = str_repeat("0", ($size - $x)); $stars = str_repeat("*", ($x*2)+1); $tree .= $spacer . $stars . $spacer . "\n"; } $spacer = str_repeat("0", ceil($size/2)-1); $tree .= $spacer . "*" . $spacer . "\n"; $tree .= $spacer . "*" . $spacer . "\n"; $tree .= $spacer . "*" . $spacer . "\n"; return $tree; } function DisplayChar ($type, $char) //display leave color when $char = "*" and background color when $char = "0" //according to the tree type { $colors = array("red", "gold"); if ($type === "Holiday") $colors = array("red", "green"); if ($type === "SacState") $colors = array("gold", "green"); //if ($type === "surprise") if ($char != 0 && $char != "*") return $char; if ($char == 0) return '0'; if ($char == '*') return '*'; } //find DisplayChar function body outline from PHP notes in SacCT and put the completed version here if($type=="Holiday") { if($char=="0") {echo("$char");} else {echo("$char");}; } else if($type=="SacState") { if($char=="0") {echo("$char");} else {echo("$char");}; } else if($type=="Surprise") { if($char=="0") {echo("$char");} else {echo("$char");}; } //display greeting of the given tree type function DisplayGreeting($type, $size = 9) { $tree = GenerateTree($size); $coloredTree = ""; foreach (str_split($tree) as $char) { $coloredTree .= DisplayChar($type, $char); } return $coloredTree; } //find DisplayGreeting function body from PHP notes in SacCT and put it here { If($type=="Holiday") { $message="Happy Holidays!!!"; } else if($type=="SacState") { $message="Go Sac Hornets!!!"; } else if($type=="Surprise") { $message="Cake is a lie!!"; } echo("$message "); } ?> But now I am getting a fatal error: Fatal error: Call to undefined function: str_split() in /gaia/class/cs0104/cs010415/html/gt_functions.php on line 85 This is my first time using the str_split and I think I missused it, anyone know how I can fix it?

The help I need is to set up the tree, so the function DisplayChar ($type, $char) I don't know the coding to color in the tree.

Hi guys, I just started programming and I need some help. For my class I need to create a christmass tree generator but I really don't know how. Here is the instructions: Input: user's choice of greeting tree type. You are required to provide the following three type options: Holiday, Sac State, Surprise. You may implement them using Radio Buttons which are used when you want the user to select one of a limited number of choices. Refer to your on-line calculator for use of radio buttons in the program examples. Output: display the greeting tree pattern and a greeting message based on the user's request. For example, for choice of "holiday greeting tree", the generator display the following pattern with two major colors: red (for 0) and green (for *). 00000000000 00000000000 00000*00000 0000***0000 000*****000 00*******00 0*********0 00000*00000 00000*00000 00000*00000 00000000000 Happy Holidays! For choice of "Sac State", the two major colors are: gold (for 0) and green (for *); and for choice of "surprise", the two major colors can be any two of your favorite colors. Here is an example of greeting tree generator. For choice of color, you may find this site helpful to you. You can pick the color and use its corresponding hexadecimal color code in your ! Extra Credit (30%): collect one more input from the user: size of the greeting tree, an odd integer between 9 and 17 (or other range you can display in full in one screen). This improved one should be able to generate the three different greeting trees in different sizes. Programming Requirements You may use two PHP files as you did in time-table generator: (a) an include file contains all of the functions, called gt_functions.php; and (b) a main program, called Greeting_tree.php. First, edit the two files based on the outline given below and then load them to your web space. Second, make a link to Greeting_tree.php from your home page, index.html. Third, debugging your program -- always remember to test each file incrementally -- make one change at a time and then check from your home page to see if it is working. Repeat this debugging process until the application is working. Here is the coding I have so far: Greeting_tree.php <?php /* Your brief description of this program which may include input, output, requirements, and your design highlights */ include_once("gt_functions.php"); # MAIN-PROGRAM $title = "The Greeting Trees"; html_begin ($title, $title); if ($submit) { if (!$type) { // your user input validation error message goes here to remind the user to select a tree type // you can reuse the input validation code in calc.php here } else { //set up the data in a 2-dimensional array to mark the background $A =array(array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0"), array("0","0","0","0","0","0","0","0","0","0","0")); //this array A is 11x11, therefore the center of a row is 5 $N = 11; $center = 5; //mark tree leaves for ($i=0; $i < 5; $i++) { for($j= ($center - $i); $j<= ($center + $i); $j++) { $A[$i+2][$j]= "*"; } } //mark tree trunk for ($i = 7; $i < 10; $i++) { $A[$i][$center] = "*"; } //display elements of the array in colors of the tree type for ($i=0; $i< $N; $i++) { for($j=0; $j< $N; $j++) { DisplayChar ($type, $A[$i][$j]); } echo " "; } DisplayGreeting($type); } } //Form to collect user input: one of the 3 greeting tree types ?> <FORM METHOD="post" ACTION="Greeting_tree.php"> Please select a tree type: <input TYPE="radio" NAME="type" >Holiday <input TYPE="radio" NAME="type" >SacState <input TYPE="radio" NAME="type" >Surprise <INPUT TYPE="submit" NAME="submit" VALUE="Display the tree"> </FORM> <? html_end () ?> gt_functions.php <?php # A collection of functions that will be included in Greeting_tree.php function html_begin ($title, $header) { print ("<HTML>\n"); print ("<HEAD>\n"); if ($title) print ("<TITLE>$title</TITLE>\n"); print ("</HEAD>\n"); if ($header) print ("<H2>$header</H2>\n"); } function html_end () { print ("</BODY></HTML>\n"); } function DisplayChar ($type, $char) //display leave color when $char = "*" and background color when $char = "0" //according to the tree type { //find DisplayChar function body outline from PHP notes in SacCT and put the completed version here $colors = array('red', 'gold'); if ($type === 'holiday greeting tree') $colors = array('red', 'green'); if ($type === 'Sac State') $colors = array('gold', 'green'); //if ($type === 'surprise') if ($char != 0 && $char != '*') return $char; if ($char == 0) return '0'; if ($char == '*') return '*'; } function DisplayGreeting ($type) //display greeting of the given tree type { //find DisplayGreeting function body from PHP notes in SacCT and put it here If($type=="Holiday") { $message="Happy Holidays!!!"; } else if($type=="SacState") { $message="Go Sac Hornets!!!"; } else if($type=="Surprise") { $message="Cake is a lie!!"; } echo("$message "); } ?>
