I have very little knowledge about programming and coding and php, but I am tutoring myself on these. I want to write a code that will search for a movie in this website search => http://myandyourface.com/DELETE/imdb-poster.php. NOTE: in searching for the movie, the movie name with more than one word can be type in in combination form by using the + sign. For example, the movie "the vow", typing that into the search box will be so => the+vow. As an example, I got the result as show below: {"Title":"The Vow","Year":"2012","Rated":"PG-13","Released":"10 Feb 2012","Genre":"Drama, Romance","Director":"Michael Sucsy","Writer":"Jason Katims, Abby Kohn","Actors":"Rachel McAdams, Channing Tatum, Sam Neill, Jessica Lange","Plot":"A car accident puts Paige (McAdams) in a coma, and when she wakes up with severe memory loss, her husband Leo (Tatum) works to win her heart again.","Poster":"http://ia.media-imdb.com/images/M/MV5BMjE1OTU5MjU0N15BMl5BanBnXkFtZTcwMzI3OTU5Ng@@._V1_SX320.jpg","Runtime":"N/A","Rating":"N/A","Votes":"N/A","ID":"tt1606389","Response":"True"} So, this is what I wanted to do, I wanted to write a php code expression that will search for a specific movie and provide the result as above,and then using the regex and str_replace, and others, I will be able to remove all the above detail information and have ONLY the image link as in above, which is => http://ia.media-imdb.com/images/M/MV5BMjE1OTU5MjU0N15BMl5BanBnXkFtZTcwMzI3OTU5Ng@@._V1_SX320.jpg I will appreciate any help in creating a code for this Thanks! Hi people,
i need to find 16x150gr in Dried Pomegranate Arils16x150gr but the format can vary from
Mt Ceder Balsamic Vinegar 12x250ml to
Mt Ceder Balsamic Vinegar 2x2ltr to
Dried Kalamata Olives 4x1kg. i guess you got the drift
i tried something like : '/[1-9]+x[1-9]+[a-z]+/' but i am so useless at regex.
Thank you!
Hey I'm pretty new to regular expression, so I might have made a silly mistake. I want to check if there are any symbols/special characters (not letters or numbers) in a string. I have the code below. function validateKeywords($kw) { if (preg_match("/[^A-Za-z0-9]/", $kw)) { echo 'validation of keywords failed<br />'; return false; // String contains symbols (not letters or numbers) - incorrect format! } else { echo 'validation of keywords succeeded<br />'; return true; // Correct format } } // Testing validateKeywords('some random string I wrote for testing purposes'); // should succeed validateKeywords('some random 10 string I wrote for testing purposes 2010'); // should succeed validateKeywords('some random, string, I wrote for 19 testing purposes'); // should fail validateKeywords('some, random, string I wrote, for testing purposes'); // should fail The problem is that all 4 calls return false and print that the validation failed. So, where did I mess up? Thanks! This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=323012.0 Hi; i would like to search for a regular expression to grab all printf occurences including the folowing senarios :
printf("something");
printf("something", variables);
printf("something", variables,
variables);
printf("something);something",
variables, variables);
To simplify the third and fourth cases, the regex should start from printf(" and go intil it find ); with a white space after it. But i didn't realise how to do it. This trick should work also for the first and second case.
Thanks
Edited by Dareros, 26 September 2014 - 01:27 PM. Hi, I've got a form where the user submits a date as a text field (as 12-12-2012 for example) called closing. The form submits fine without my regular expression validation, but whenever I try to validate it, it returns the error message I wrote for if no results turn up. Ive tried: Code: [Select] <?php if (!preg_match ("[0-9]{2}-[0-9]{2}-[0-9]{4}", $_POST["closing"])) { $_SESSION["report"] = "<b>Error:</b> Date is in the wrong format. It must be dd-mm-yyyy<br />"; $_SESSION["reportcount"] = 0; } ?> and Code: [Select] <?php if (!preg_match ("\d{2}-\d{2}-\d{4}", $_POST["closing"])) { $_SESSION["report"] = "<b>Error:</b> Date is in the wrong format. It must be dd-mm-yyyy<br />"; $_SESSION["reportcount"] = 0; } ?> Any ideas? Ok I decided to brush up on some functions and this one was giving me a hard time. Basically the if condition is printing the statement even though its not what the expression was asking for. I'm positive I am just missing something small, but I can't figure it out.

I have a file to display
$file_content = file_get_contents("test.php");
This file is encoded....
In this file there is a specific tag call change_me
<change_me> "<code> <strong>Example Element</strong> </code>" </change_me>I want to use htmlspecialchars_decode function for <change_me> tag only... <change_me> tag is used two times in file.

Can somebody share his scripts? or lead me to the right directions? Hope you can help! Thanks a lot! My boss is gonna kill me soon. This is 1 week overdue already.

About 3 weeks into this. I have this simple expression and some echo in my code. $x1 = $lat_b + $lat_a1; echo "<br>lat b: ".$lat_b; echo "<br>lat a1: ".$lat_a1; echo "<br>x1: ".$x1; $lat_b and $lat_a1 are derived from some xml extractions from a yahoo geocode api (that part works fine). The results of the expression and echos above are as follows: lat b: 40.402866 lat a1: 40.252590 x1: 80 Why is $x1 rounding automatically on me? Later, I substituted the expression above with $x1 = 40.402866 + 40.252590 ; The new result (shown below) makes sense to me. lat b: 40.402866 lat a1: 40.252590 x1: 80.655456 |
