papaface Posted February 22, 2007 Share Posted February 22, 2007 Hello, I need to know how to access the array so i can find a certain key and its value e.g. $array[4]; The code i have is: example.php <?php /* GRADIENT CLASS EXAMPLE */ require "class.gradient.php"; $fade_from = "#FFffff"; // HEX-Color to fade from $fade_to = "#000000"; // HEX-Color to fade to $steps = 15; // number of steps creating the gradient $gradient = new gradient($fade_from,$fade_to,$steps); // define the class echo "Gradient from <b>".$gradient->color1."</b> to <b>".$gradient->color2."</b></p><pre>"; print_r($gradient->createArray()); // outputs the array to see the values echo "</pre><table width='300' border='0'>"; // creates the table with colors foreach($gradient->createArray() AS $color){ echo "<tr><td bgcolor=$color> </td><td>$color</td></tr>"; }; echo "</table>"; ?> class.gradient.php <?php class gradient { var $color1 ; var $color2 ; var $n = 10; var $c1codes; var $c2codes; /* constructor */ function gradient($color1,$color2,$n){ $this->color1 = $color1; $this->color2 = $color2; $this->n = $n; $this->c1codes=$this->getHexValues($this->color1); $this->c2codes=$this->getHexValues($this->color2); } /* internal: do not call */ function getHexValues($color) { $color = substr($color, 1); return array(hexdec(substr($color,0,2)),hexdec(substr($color,2,2)),hexdec(substr($color,4,2))); } function createArray(){ $red=($this->c2codes[0]-$this->c1codes[0])/($this->n-1); $green=($this->c2codes[1]-$this->c1codes[1])/($this->n-1); $blue=($this->c2codes[2]-$this->c1codes[2])/($this->n-1); for($i=0;$i<$this->n;$i++){ $newred=dechex($this->c1codes[0]+round($i*$red)); if(strlen($newred)<2) $newred="0".$newred; $newgreen=dechex($this->c1codes[1]+round($i*$green)); if(strlen($newgreen)<2) $newgreen="0".$newgreen; $newblue=dechex($this->c1codes[2]+round($i*$blue)); if(strlen($newblue)<2) $newblue="0".$newblue; $return[$i]="#".$newred.$newgreen.$newblue; } return $return; } } ?> In example.php you will see $gradient->createArray()) How do get a hold of that array that it creates so i can get a value depending on the key i want? Any help would be appreciated. Link to comment https://forums.phpfreaks.com/topic/39664-how-do-i-access-this-array/ Share on other sites More sharing options...
