I have the following array which builds a concatenation of the items in tree-like form. $arrayT = array(); $arrayT[0] = "a"; $arrayT[1] = "b"; $arrayT[2] = "c"; $arrayT[3] = "d"; $arrayT[4] = "e"; $arrayT[5] = "f"; $arrayT[6] = "g"; $arrayT[7] = "h"; $arrayT = buildTree($arrayT); print_r($arrayT); function buildTree($array) { $arrayTree = $array; $start = 0; $end = count($arrayTree); $i = 0; while ($start != $end - 1) { if ($i % 2 == 1) { $arrayTree[count($arrayTree) - 1].=$arrayTree[$start + $i]; } else $arrayTree[] .= $arrayTree[$start + $i]; $i++; if (($start + $i) == $end) { $i = 0; $start = $end; $end = count($arrayTree); } } return $arrayTree; } Example output is I would like the values to be hashed using sha1. e.g value at [8] ab would be the hash of [0]a and [1] b, value [12]abcd would be the hash of the values at [8]ab and [9]cd. I modified it myself in the next code snippet but I still don't feel it's doing what it's meant function buildTree($array) { $arrayTree = $array; $start = 0; $end = count($arrayTree); $i = 0; while ($start != $end - 1) { if ($i % 2 == 1) { $arrayTree[count($arrayTree) - 1].=$arrayTree[$start + $i]; sha1($arrayTree[count($arrayTree)-1].=$arrayTree[$start + $i]); } else $arrayTree[] .= sha1($arrayTree[$start + $i]); $i++; if (($start + $i) == $end) { $i = 0; $start = $end; $end = count($arrayTree); } } return $arrayTree; } $val1 = sha1($arrayT[0]); $val2 = sha1($arrayT[1]); $val3 = sha1($val1.$val2); $val4 = sha1("ab"); echo "VAL1 ".$val1; echo "<br/>"; echo "VAL2 ".$val2; echo "<br/>"; echo "VAL3 ".$val3; echo "<br/>"; echo "VAL4 ".$val4; Anyone any ideas? Thankyou.

Thanks! I realised this yesterday after posting but forgot to come back and edit Thank you.

I am including my test.php for other to run. I have a very large array of concatenated hash values. I have another array that contains the first 8 hash values of the other array. I have a function to locate them in the larger array. Depending on their index value I then choose the index of the value before or behind them for adding to something else later. This 'computeWalk' method works for small arrays but for larger arrays I notice duplicates or errors with larger ones. For example. The first array returns: Array ( [0] => 1 [1] => 18 [2] => 18 [3] => 35 [4] => 33 [5] => 33 ) The values for i's to get each of these values are I = 0 I = 19 I = 29 I = 34 I = 37 I = 39 Walking through the method by hand, 0%2 = 0 So the first element of the array will be 1. CORRECT. 19%2 = 1 So the next element will be 18. CORRECT. 29%2 = 1 The next element should be 28. It returns 18. 34%2 = 0 The next element will be 35. Correct. 37%2 = 1 The next element should be 36. It returns 33. 39%2 = 1 The next element should be 38. It returns 33. I am not sure why it's doing the above. I also tried array_search and it computed it the same way. Would appreciate any help. <?php $arrayTree = array(); $arrayTree[0] = "9d027b1c4068d81287c9170f4b291387f8327eb7"; $arrayTree[1] = "4c8fabdc24c2d8205db916a22e9459195833a272"; $arrayTree[2] = "209526afab9e85b54e1832a820a7f578b7760af0";

I am using TCPDF & FPDI together to create and merge PDF's. I create a PDF with a link embedded in html and then merge it with another PDF. After merging, the link is only clickable if I pass in the link as // Set some content to print $html = <<<EOD <A HREF="http://www.helloworld.com">http://www.helloworld.com</A> EOD; $pdf->writeHTML($html, true, 0, true, 0); It is no longer clickable if I pass in the link as $html = <<<EOD <A HREF="http://www.helloworld.com">Visit Link</A> EOD; $pdf->writeHTML($html, true, 0, true, 0); I would like to pass it in the above way as the actual link I'm using is very long/tedious looking. Can anyone help here?

Thanks, checking those out now

I have a bunch of pdf's and I want to extract text from the last page of every pdf. I have a function to count the number of pages in each pdf. Does anyone know of a way that I could extract file from a specified file and page number. example: getData('example.pdf', 54);

i also have this problem
