Say I have a form field where I input any text(numbers,text,symbols, or mixed). I want to encrypt that input into 16 characters long encryption string that includes at least one uppercase letter, one lowercase letter, one number and one special character? How can that be done? Also I want to decrypt it back to original input as well. Can that be one?

I am trying to write post variables to a csv file but it writes everything in one line separated by comma <?php $list= array($_POST['purchases']); $file = fopen("purchases.csv", "w"); foreach ($list as $line) { fputcsv($file, $line); } fclose($file); ?> Result in purchases.csv file Marilyn,Nancy,Johan,Carol,Juanic,Shirley But I want every string value on separated line Marilyn Nancy Johan Carol Juanic Shirley

I have a DB of data: article-id, section-id, subsection-id, article-text. When a row is fetched I am displaying article, section, subsection as <h3>, <h4>, <h5> and then text in a <p>. Before outputting the text I want to scan it for other articles, sections, or subsections it may reference then turn that reference into a hyperlink. I read the PHP documentation but I can't find anything that translates to the basic commands of instring, indexof, and left/mid/right. Example: 1. Article Name 100. Article 1, section 1 100.a article 1, section 1, subsection a Text blah blah blah 105.f blah blah blah I want to find that 105.f and turn it into a link. All my articles, sections, and subsections are in the DB so I know I can use an array of the number values as my items to look for, but I can't figure out how to look.

For right or wrong, I've been using XML to define my Doctrine entities. When the XML changes, my entities need to change. I've automated the process with a simple PHP script which allows me to swap some text to modify one of the auto-generated methods, add methods, etc. Kind of clunky but it works well enough. Now, I recently had the need to remove a given method in its entirety from a given class. I "could" just add the entire string which represents the method name, earlier comments, and script for the method to my parsing script to my parsing script and remove it, but would like to be a little more concise. For instance, say I have $script as follows: $script = <<<'EOT' class SomeEntityClass { //... more stuff above public function getSomething() { return $this->something; } /** * Get foos. * * @return \Doctrine\Common\Collections\Collection */ public function getFoos() { return $this->foos; } /** * Get somethingElse. * */ //... more stuff below } EOT; How would you recommend creating the function: removeFunction($script, 'getFoos') which would remove the given function along with its comments from the $script string and result with? $script = <<<'EOT' class SomeEntityClass { //... more stuff above public function getSomething() { return $this->something; } /** * Get somethingElse. * */ //... more stuff below } EOT; Assuming regex is the way to go, I was thinking of something like the following, but could use some help with the regex expression. function removeFunction($script, $method) { $method="public function $method("; //regex to remove script with which starts after pattern "{\n" OR "**/", contains $method, and is located before pattern "\n{" OR "\n /**" return $script; } Thanks
