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 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.

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/"; }

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

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.
