PHP - Need Help With Curl And Preg_match
hello there, i want to preg_match someting from curl "keywords"
example <meta content='bla bla bla...' name='description' /> <meta content='bla bla bla...' name='keywords' /> how you can see all start disame with " <meta content=' " how i can make the preg_match to get the last " <meta content=' " and not the first one, i just need the preg_match command i try this command ... $patterns[3] = '/(?:.*)<meta content=\'(.*?)\' name=\'description\' \/>(?:.*)/i'; $replacements[3] = 'Desc=[$1]<br />'; Similar Tutorialsgood day dear community, i am workin on a Curl loop to fetch multiple pages: i have some examples - and a question: Example: If we want to get information from 3 sites with CURL we can do it like so: $list[1] = "http://www.example1.com"; $list[2] = "ftp://example.com"; $list[3] = "http://www.example2.com"; After creating the list of links we should initialize the cURL multi handle and adding the cURL handles. $curlHandle = curl_multi_init(); for ($i = 1;$i <= 3; $i++) $curl[$i] = addHandle($curlHandle,$list[$i]); Now we should execute the cURL multi handle retrive the content from the sub handles that we added to the cURL multi handle. ExecHandle($curlHandle); for ($i = 1;$i <= 3; $i++) { $text[$i] = curl_multi_getcontent ($curl[$i]); echo $text[$i]; } In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle! If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it! Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages: see the some details for this target-server sites - /(I have to create a loop over several hundred sites). * siteone.example/?show_subsite=9009 * siteone.example/?show_subsite=9742 * siteone.example/?show_subsite=9871 .... and so on and so forth Question: How to appy this loop into the array of the curl-multi? <?php /************************************\ * Multi interface in PHP with curl * * Requires PHP 5.0, Apache 2.0 and * * Curl * ************************************* * Writen By Cyborg 19671897 * * Bugfixed by Jeremy Ellman * \***********************************/ $urls = array( "siteone", "sitetwo", "sitethree" ); $mh = curl_multi_init(); foreach ($urls as $i => $url) { $conn[$i]=curl_init($url); curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);//return data as string curl_setopt($conn[$i],CURLOPT_FOLLOWLOCATION,1);//follow redirects curl_setopt($conn[$i],CURLOPT_MAXREDIRS,2);//maximum redirects curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,10);//timeout curl_multi_add_handle ($mh,$conn[$i]); } do { $n=curl_multi_exec($mh,$active); } while ($active); foreach ($urls as $i => $url) { $res[$i]=curl_multi_getcontent($conn[$i]); curl_multi_remove_handle($mh,$conn[$i]); curl_close($conn[$i]); } curl_multi_close($mh); print_r($res); ?> I look forward to your ideas. I need to select an array item based on my preg result. for example: Code: [Select] $content = 'test-1'; $match = preg_replace('|test-([0-9])|', $array['\\1'], $content); is this possible? Hi im trying to do a registration form and i am new to using preg_match. I keep getting the error "( ! ) Warning: preg_match() [function.preg-match]: No ending delimiter '^' found in C:\wamp\www\registration1.php on line 67" and for every other line I use preg_match. this is an example of how i have used it Code: [Select] if ( preg_match('^[[:alnum:]\.\'\-]{4,50}$', stripslashes(trim($_POST['UserName']))) ) { $UserName = mysql_real_escape_string($_POST['UserName']); $query = "SELECT UserName FROM Users WHERE UserName = '$UserName'"; $result = @mysql_query($query); $num = @mysql_num_rows($result); im such a noob at this can someone please help me I would also like to add that I have read the http://www.php.net/manual/en/function.preg-match.php page but i dont really understand it. I know $regex_pattern is wrong but I need a solution to find a content between <body> and </body>. Code: [Select] <?php $content = "<html><head><title>Your IP</title></head><body>Your IP Address: 63.1.142.154</body></html>"; $regex_pattern = "/<body>(.*)<\/body>/"; $preg_match($regex_pattern,htmlspecialchars($content),$matches); print_r( $matches ); ?> Hi,
I don't know much about php. Recently my host updated php version to 5.4 and i function eregi() is deprecated errors, so after some googling, replaced it with preg_match but i am stuck with errors
Code:
preg_match("^ and", "", $mid_str)
Error: Warning: preg_match(): No ending delimiter '^' found
Tried the following method but not working
preg_match("/^ and/", "", $mid_str)
Can you guys help me with correct code?
Thanks for looking.

Hi guys, I have been using this code: preg_match('/<h2>(.*?)<\/h2>/', $data, $matches); which i changed to: $tag1 = 'h2'; $tag2 = 'h2'; preg_match('/$tag1(.*?)$tag2/', $data, $matches); however i need it to work allowing variables (of any character or symbol) within $tag1. I tried $tag1 = 'h(.*?)2'; $tag2 = 'h2'; preg_match('/$tag1(.*?)$tag2/', $data, $matches); but that does not work .... essentiall the whole thing would work like this (example only): firstpartoftag1VARIABLE1lastpartoftag1VARIABLE2tag2 ps the preg_match should only capture the VARIABLE2 data not VARIABLE1 any ideas or help would be much appreciated cheers in advance I've tried alot of different ways, google, but just can't find the correct way to do this.. I'm trying to search for a word in an inputted string.. here's the code <html> <head><title>TESTING</title></head> <body> <form method="GET" action="<?php echo $_SERVER['PHP_SELF']; ?>"/> email: <input type=text name=email value="" /><br/> feedback: <input type=text name=ex value=""/><br/> <input type="submit" value="submit" /><br/> </body> </html> <?php $email = $_GET['email']; $ex = $_GET['ex']; $pattern = '/^[a-zA-Z0-9\-\.]+@[a-zA-Z0-9\-]+\.[a-zA-Z]+$/'; //$pattern1 = '/nprezident/prezident/'; if(!preg_match($pattern, $email)){ echo 'invalid email address<br/>'; } else { echo 'good to go<br/>'; } if(preg_match('/nprezident/,/prezident/', $ex)){ echo 'just something about that sentence is nice'; } else { echo 'no good'; } ?> Ok the one I'm having a problem with is the second preg_match when trying to search for two words i can get one word to print but when i use add a second word it gives an error. How do i add a second word? in my site search some of the results come out still with html. i have used the strip tags function but how would i use the preg_match function to get rid of the "> still left over?

Hi,
I have a "scraped" string and want to use the preg_match() to give me just a pice of it.
The string is from a webpage, but is dynamic....
here´s the typical string format:
<a class="stripped-link lightblue-link profile-page-link" href="/x/xxx+xxx+xxx/xxxx">HER IS THE WANTED TEXT</a>
The orange is static. The green (the xxxx is the dynamic part of the string)
Can I use the preg_match() for this?
thanks (and yes I´m a newbe.... )
Im trying to match this string, but i dont wat to match normal words like "hello world 646" Code: [Select] $string = "2ab055843241f20044af82ae0d5ace04"; //always over 15 chars - without spaces if ( preg_match('~^[0-9\s]+$~D', $string)) { echo 'yes'; } If i can do it with preg_match that would be great Why dosent this work, im trying to match upper case, lower case and numbers only Code: [Select] $id = '3xDJ7@#'; if (!preg_match('/^[a-zA-Z0-9]/', $id)){ echo "ERROR!"; }else{ echo 'ok'; } This always echos "ok" I'm pretty new to this, How exactly could i get the text between the www. and .com? so if i have a url: http://www.facebook.com I want to just return "facebook" I have a DOMDocument which I inspect an HTML page for links (href) That part works however I am not sure how to use preg_match if I only want to display a link in this layout: <tr> <td headers="c1"><a title="Link to entity information." tabindex="1" href="CORPSEARCH.ENTITY_INFORMATION?p_nameid=3236937&p_corpid=3227476&p_entity_name=%41%72%77%65%6E%20%45%71%75%69%74%69%65%73&p_name_type=%41&p_search_type=%42%45%47%49%4E%53&p_srch_results_page=0">ABC LLC</a></td> </tr> I hope someone is really good at preg_match to help me.

I'm not sure how to change preg_match_all to work!! i've tried loads of combinations but can't get any to work, but i'm not really sure on modifiers and patterns or escaping etc, if anyone could help that would be great. Thanks in advance kev. When I use the following code to check for posted characters it allows the insertion of ( ) brackets to be posted. if(!preg_match('/^([-_ a-z0-9]){2,50}$/i', $_POST['title'])) { echo "<script>alert('Please enter a Title 2-50 alphanumeric characters,\\nspaces, hyphens and underscores also accepted!)</script>"; } It should on allow 2-50 alphanumeric characters and spaces, hyphens and underscores! What am I missing? |
