  1. I have problems with a script. The error log says I should change the preg_replace to preg_replace_callback I dont know how to do it, so please help. function __unserialize($string) { $unserialized = stripslashes($string); $unserialized = preg_replace('!s:(\d+):"(.*?)";!e', "'s:'.strlen('$2').':\"$2\";'", $unserialized ); return unserialize($unserialized); } Edit: I did try to do it. so if you want to see what I tried I ofcourse can show. But it reutned a blank screen
  2. I have a file in the same location as my PHP file, say test.txt, and in multiple locations it has content like: - href="http://www.domain.com/entry.php/256/1/this-is-the-title" or href="http://www.domain.com/entry.php/123/2/another-title" which I need replaced within the file to: - href="{EntryNumber=256.link}" and href="{EntryNumber=123.link}" Only the first number is needed for the replacement, it will be between 1 and 999. Everything between the 5th / and the 2nd " can be safely ignored and removed. This is not the only content in the line, and sometimes there may be more than one occurrence per line. I've got this so far: - $buffer = ""; $fp = file($file); foreach($fp as $line){ $buffer .= preg_replace(***struggling with this bit***); } fclose($fp); echo $buffer; file_put_contents($file, $buffer); Am I along the right lines generally? And I have no idea what the preg_replace should be as my regex is a bit trial and error, more error in this case... As always, any help greatly appreciated! EDIT: If it matters, the largest file I need to edit is 39Kb, and includes 175 occurrences of the replacements.
  3. I need to create a SEO friendly string only from alphanumeric and characters of my native language. It is sinhala. My expected string should be something like this: $myString = "this-is-a-දහසක්-බාධක-දුක්-කම්කටොලු-මැදින්-ලෝකය-දිනන්නට-වෙර-දරන"; I am using a function to create the string like this. And that function is as follow: function seoUrl($string) { //Lower case everything $string = strtolower($string); //Make alphanumeric (removes all other characters) $string = preg_replace("/[^a-z0-9_\s-]/", "", $string); //Clean up multiple dashes or whitespaces $string = preg_replace("/[\s-]+/", " ", $string); //Convert whitespaces and underscore to dash $string = preg_replace("/[\s_]/", "-", $string); return $string; } This function only works for English characters and output of above string as below: $title = seoUrl("this-is-a-දහසක්-බාධක-දුක්-කම්කටොලු-මැදින්-ලෝකය-දිනන්නට-වෙර-දරන"); echo $title; // this-is-a- I modified this function using `mb_ereg_replace` as below: function seoUrl($string) { //Lower case everything //$string = strtolower($string); //Make alphanumeric (removes all other characters) $string = mb_ereg_replace("/[^a-z0-9_\s-]/", "", $string); //Clean up multiple dashes or whitespaces $string = mb_ereg_replace("/[\s-]+/", " ", $string); //Convert whitespaces and underscore to dash $string = mb_ereg_replace("/[\s_]/", "-", $string); return $string; } But is not working for me. Can anybody tell me how to modify above function to get all my characters (including my native language characters) Hope somebody may help me out. Thank you.
  4. Hi, I'm using TCPDF to create a PDF from a webpage. This works great but I have the following problem: I'm building in WordPress and as you may know WP saves images on different sizes. (e.g. 150x150, 300x300 and 1024x1024) The thing I'm trying to create is that users can download a PDF ready for printing. So High Resolution images. I use a preg_match_all function to match the image source and remove the additional image size from the filename so the original high resolution image is loaded. e.g. image-150x150.jpg will be replaced by image.jpg. So now the original image that has a image size of 6024x6024px and 300 DPI is loaded. Then TCPDF uses a resize function that resizes the image back to 150x150 px but sets the DPI to 300 so it can be printed on a good quality. This all works but now the problem comes: If I do the preg_match_all function the image gets "pulled" from the rest of the content and looses it's position. So my thought to fix this was. Get a preg_replace function and replace the image tag with a function that executes the whole image change like described above. This doesn't work...... So i'm stuck here. Hope anyone can assist me with this. Here is what I have done so far. function execute(){ preg_match_all("/<img[^>]+src=(?:\"|\')\K(.[^\">]+?)(?=\"|\')/",$content,$matches,PREG_PATTERN_ORDER); for( $i=0; isset($matches[1]) && $i < count($matches[1]); $i++ ) { $search = array('-'.$s1.'x'.$s2.'', '-'.$s3.'x'.$s4.'', '-'.$s5.'x'.$s6.''); $replace = array('', '', ''); $a = $matches[1][$i]; if (strpos($a,'-'.$s1.'x'.$s2.'') !== false) { $w = $s1; $w = $pdf->pixelsToUnits($w); $h = $s2; $h = $pdf->pixelsToUnits($h); $l = '57'; $l = $pdf->pixelsToUnits($l); $t = '170'; $t = $pdf->pixelsToUnits($t); }elseif (strpos($a,'-'.$s3.'x'.$s4.'') !== false) { $w = $s3; $w = $pdf->pixelsToUnits($w); $h = $s4; $h = $pdf->pixelsToUnits($h); $l = '217'; $l = $pdf->pixelsToUnits($l); $t = '20'; $t = $pdf->pixelsToUnits($t); }elseif (strpos($a,'-'.$s5.'x'.$s6.'') !== false) { $w = $s5; $w = $pdf->pixelsToUnits($w); $h = $s6; $h = $pdf->pixelsToUnits($h); $l = '57'; $l = $pdf->pixelsToUnits($l); $t = '310'; $t = $pdf->pixelsToUnits($t); } $content .= $pdf->Image(str_replace($search,$replace,$matches[1][$i]), $l, $t, $w, $h, 'JPG', '', '', true, 300, '', false, false, 0, false, false, false); } }; global $post; $id = $_GET['id']; $content_post = get_post($id);// get the content $content = $content_post->post_content; $content = apply_filters('the_content', $content); $content = str_replace(']]>', ']]>', $content); $content = preg_replace('/<img[^>]+./e',execute(), $content); // replace the image tag with the new image // EXPORT IT ALL $pdf->writeHTML($content, true, false, true, false, '');
