PHP - Turn Php Function Text Into Links
Say I have a chunk of code that looks like this (contains imagesx):
Code: [Select] <span style="color: #0000BB">$width </span><span style="color: #007700">= </span><span style="color: #0000BB">imagesx</span><span style="color: #007700">(</span><span style="color: #0000BB">$img</span><span style="color: #007700">); <br /> within the code I would like to make all the php functions link to php.net I thought that the following code would work, but it does not, well because there is no spaces around the above word public function phpLinks($string){ $words = explode(" ", $string); $str = array(); foreach($words as $word){ if(function_exists($word)){ $str[] = preg_replace("/$word/i", '<a href="//php.net/'.strtolower($word).'">'.$word.'</a>', $word); }else{ $str[] = $word; } } return implode(" ", $str); } I now can not think of a good way to do this, so I am asking does anyone have any suggestions? Similar TutorialsHello All, I'm trying to put a lot of what I do into function calls now to make my code a bit tidier and consise. Take this simple if statement: if ($_GET['thedate'] =='') { $var = date('l, jS F, Y',time()); } else { $var = date('l, jS F, Y', strtotime($_GET['thedate'])); } How could I put this into a function and in some kind of switch statement? Thanks I'm trying to crawl for links in a specific website and show them at the end. The problem i'm facing is that it only show the links from the specific page not the whole pages in the website. I tried several loops with no success please give some advise. Here is the code: <?php if (isset($_POST['Submit'])) { function getLinks($link) { /*** return array ***/ $ret = array(); /*** a new dom object ***/ $dom = new domDocument; /*** get the HTML (suppress errors) ***/ @$dom->loadHTML(file_get_contents($link)); /*** remove silly white space ***/ $dom->preserveWhiteSpace = false; /*** get the links from the HTML ***/ $links = $dom->getElementsByTagName('a'); /*** loop over the links ***/ foreach ($links as $tag) { $ret[$tag->getAttribute('href')] = $tag->childNodes->item(0)->nodeValue; } return $ret; } /*** a link to search ***/ $link = $_POST['address']; /*** get the links ***/ $urls = getLinks($link); /*** check for results ***/ if(sizeof($urls) > 0) { foreach($urls as $key=>$value) { if (preg_match('/^(http|https):\/\/([a-z0-9-]\.+)*/i',$key)) { echo '<span style="color:RED;">' . $key .' - external</span><br >'; } else { echo '<span style="color:BLUE;">' . $link . $key . ' - internal</span><br >'; } } } else { echo "No links found at $link"; } } ?> <br /><br /> <form action="" method="post" enctype="multipart/form-data" name="link"> <input name="address" type="text" value="" /> <input name="Submit" type="Submit" /> </form> I am trying to use the php mail function and want to include links to a dynamic page, so I need to know how to do this... Something like: Code: [Select] $id=$_POST['id']; $mailto="email@address.com"; $mailsub="Subject"; $mailhead="From: other@address.com"; $mailbody="Your comment has been posted. You may view it by <a href='domain.com/page.php?id=".$id."'>clicking here</a>."; mail($mailto, $mailsub, $mailbody, $mailhead); I know this is not correct but I'm trying to figure out the actual way to do this... Looking for help writing a function that does the following: Look for http:// or https:// in a string and replaces it with an <a href> tag. For example: Here is my link http://www.mydomain.com some further text here. Becomes: Here is my link <a href="http://www.mydomain.com">http://www.mydomain.com</a> some further text here. The Issue (note: sorry for double post in the regex forum.) My users can post comments. I want to turn the hidden links within those comments into clickable URLs. I have the following function to do this: Code: [Select] if (!function_exists('create_link')) { function create_link($url) { $pattern = "#((http|https|ftp)://(\S*?\.\S*?))(\s|\;|\)|\]|\[|\{|\}|,|\"|'|:|\<|$|\.\s)#ie"; $link_title = character_limiter(preg_replace($pattern, "$3", $url), 50); $link = preg_replace($pattern, "'<a href=\"$1\" target=\"_blank\">{LINK_TITLE}</a>$4'", $url); if ($link == $url) { $url = 'http://' . $url; $link = preg_replace($pattern, "'<a href=\"$1\" target=\"_blank\">{LINK_TITLE}</a>$4'", $url); } if ($link != $url) { $result = str_replace('{LINK_TITLE}', $link_title, $link); } else { $result = FALSE; } return $result; } } I know that the regex is pretty bad. It kind of works, but makes every single thing with a period into a link, and messes up sometimes with target= portion where it will actually display that. I've tried a bunch of other regex's but every single one gives me problems, typically like "php unknown modifier ]" or ")" or something. here's how I call this function when users hit submit in the comment field: Code: [Select] $words = preg_split("/[\s,]+/", $comment); foreach ($words as $word) { if ($link = create_link($word)) { $comment = str_replace($word, $link, $comment); I just want to convert the right links into links. is something like: ^(((ht|f)tp(s?))\://)?(www.|[a-zA-Z].)[a-zA-Z0-9\-\.]+\.(com|edu|gov|mil|net|org|biz|info|name|museum|us|ca|uk)(\:[0-9]+)*(/($|[a-zA-Z0-9\.\,\;\?\'\\\+&%\$#\=~_\-]+))*$ any better? I don't know, nothing seems to work. I'm trying to make my text and images into clickable links. The images and text are in a database so its getting really tricky for me since I'm new to PHP. I've tried many different ways without success. Here is a snippet of the code I'm working with. As you can see, I'm also working with an image re-sizer. I would really like to make those images and text clickable links(i.e. Title). Any help is appreciated! if ($res) { while ($newArray = mysqli_fetch_array($res, MYSQLI_ASSOC)) { $detail = $newArray['id']; $photo = $newArray['photo']; $id = $newArray['title']; $price = $newArray['price']; list($width) = getimagesize($photo); // set the maximum width of the image here $maxWidth = 100; if ($width > $maxWidth) echo "<p><img alt=\"Image\" width=\"$maxWidth\" src=\"$photo\" />"; echo "Title:".$id."

Thanks - and again, sorry for my lack of php knowledge. I've tried to use this http://www.bambalam.se/bamcompile/ .. but I cant get curl to work using the option to set the extension.. I need it to be able to sign into myspace or facebook with curl when it is in an exe.. everything else works fine with bambalam, everything but curl and connecting to an mysql db, I dont need to have mysql support, only curl.. what would be the easiest way to make this happen? btw the exe should just open a CLI and run the script, thanks Hi. I have a problem with output buffering. I'm using wamp. I've tried setting the php.ini file to output_buffering = 0 and off I've tried using flush() and ob_flush(), separetly and together. I've tried turning on implicit_flush. Nothing works. Any ideas? I'm using the flowing code to test right now: Code: [Select] echo 'starting...<br/>'; for($i = 0; $i < 5; $i++) { print "$i<br/>"; flush(); sleep(2); } print 'DONE!<br/>'; Hi, How would I do this, I'm trying to create a function to turn the octal (not sure whats its called exactly) input into its numberic representation, like so: <?php function octal_to_number($input) { //do something... return $number; } //would turn 0x17c into 380... echo octal_to_number('0x17c'); ?> How do I turn a checkbox on or off programatically? My form has several checkboxes that are grouped together and I want them to be turned on initially when the user first sees the form.I can do that very easily by just including "checked" in the HTML for the checkbox. But if the user turns off the checkbox before he presses Submit, I want to make sure I show the ones that are off as off when I redisplay the form as a result of errors in other fields, like textareas. How do I turn the checkbox off or on within my PHP code?

How do you turn off a php form after a set number of submissions? My form is not hooked up to a mysql database. Theoretically I think I would need to set something up that increments a number with each successful form submission. Then when the form hits a certain limit number like 300 it shuts off or hides the div that contains the form. Has anyone done something like this before? Any help or even just pointing me in the right direction is greately appreciated! This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=347224.0 Hello Everyone, I have a quick question for you all, I think its fairly simple... I have created a database and I am using PHP to grab the data: $usera = $_SESSION['username']; $query2 = "SELECT * FROM tracker WHERE id = '$usera', hidden = yes"; mysql_query($query2) or die('Error, query failed : ' . mysql_error()); This hopefully will return multiple rows which look like this in the database. id username date reps hidden 1 supremebeing 2011-01-02 30 yes 4 supremebeing 2011-04-02 46 yes How would i turn each result into a variable eg: $date1 = 2011-01-02; $date2 = 2011-04-02; $reps1 = 30; $reps2 = 46; I think i have explained that well enough for you to understand, please reply if not though and i will provide more information. Thanks in Advance This topic has been moved to Apache HTTP Server. http://www.phpfreaks.com/forums/index.php?topic=320065.0 I think my eyes are going to fall out from all the searches ive made to find a solution for this that works on a shared host.
I tried this... but it doesnt work.
RewriteEngine on CheckSpelling onThe only Rough solution i got is to do the case manually with an internal redirect. Like this. RewriteEngine on RewriteBase /~quux/ RewriteRule ^foo\.html$ bar.htmlIs there absolutely no way to mention [a-z] and [A-Z] into a RewriteRule to get this done? I find it terribly stupid from Apache not to provide a simple solution for this. |
