Can someone please tell me why neither one of these are working: $content = str_replace(array("\r", "\n"), '', $row['content']); $content = preg_replace( "/\r|\n/", '', $row['content']); I've tried each one of the to replace $content = $row['content']; and for some ungodly reason neither one of them are working. This is simply pulling content from a database but it keeps displaying \r\n when displayed in a page. Why?

I am new to PHP, ereg_replace is deprecated so need to convert ereg_replace to preg_replace, I can't figure out how to put "delimiters and escape character" on $TEST_FILE below, can someone help me on this. function KernelBase(){ $i=0; $TEST_FILE="fdKernel/Init.php"; $TEST=$TEST_FILE; while(!file_exists($TEST)){ $TEST="../".$TEST; if($i>15) break; $i++; } return trim(ereg_replace($TEST_FILE,NULL,$TEST))."fdKernel/"; }

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, '');

The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it. For example: <?php $str = 'some blob ~abc~ followed by ~def~'; $arr_orig = array( '~abc~', '~def~' ); $arr_new = array( 'value~def~', 'blah' ); echo str_replace( $arr_orig, $arr_new, $str ); ?> This will echo: some blob valueblah followed by blah But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need. I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!)

I'm trying to search a string for all occurences of a pattern, then append text after that pattern. The example is: SUM("foo") as "bar" and have it display as: SUM("foo") over() as "bar" The "SUM" could be any SQL aggregate and be case insensitive. So For bonus points, let's say the valid aggregates are array('SUM', 'MAX', 'MIN', 'AVG'). My plan right now is to figure it out for SUM, then loop it replacing the aggregate. This is what I have so far... and it is not working. $l= 'SUM("foo") as "bar"'; $l=preg_replace('/([^"]+")/','\0 over()',$l); Thanks, Ryan
