PHP - Geting The Regular Expression From Both The Url And The Script.

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!

Can anyone help me. 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!

Code: [Select]
<pre>
<pre class="brush:cpp">
<pre class="brush:javascript">
Those can be cpp,javascript,python ... etc.

I need to change/replace these into:

Code: [Select]
<pre>
<pre class="brush:cpp">
<pre class="brush:javascript">
Those can be cpp,javascript,python ... etc.

I need a generic regular expression for this? Can anyone provide the generic regular expression for this to replace?

Trying=>

$abc = str_replace(array($generic-regular-expression),'<pre> or <pre class="brush:cpp"> or <pre class="brush:javascript"> ..... ',$str);

Hello everyone,   example string

<?php

$string = "";
$string  .= "<textarea id='convert'> 'AA' </textarea>";
$string  .= "<textarea id='convert'> 'BB' </textarea>";
$string  .= "<textarea id='not_convert'> 'AA' </textarea>";
$string  .= "<textarea id='not_convert'> 'DD' </textarea>";

?>

I want to change 'AA' to 'ZZ' which is inside textarea with the id convert only.   How is it possible with the help of regular expression?

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!
