Replace utf8 character in a certain position of a string
cataiin replied to filoaman's topic in PHP Coding Help
<?php $text = "Thîs îs ã ütf8 strîng"; $replace = array( 'i' => array('î'), 'a' => array('ã'), 'u' => array('ü') ); foreach ($replace as $changed => $initial) { $text = str_replace($initial, $changed, $text); } echo $text; ?>iconv example: <?php $text = "Thîs îs ã ütf8 strîng"; echo iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text); ?>But this will remove diacritics, and is not what you want. Use first code, sorry. -

count views: mysql_query("UPDATE apps SET views=views+1 WHERE id='".$id."'"); show 5 most viewed: mysql_query("SELECT * FROM apps ORDER BY views DESC LIMIT 0, 5"); Don't forget to add column "views". My code is just an example.

$news_title = mysql_real_escape_string($_POST['news_title']); $publish="INSERT INTO news(news_title,news_subtitle,news_desc,news_post,news_date,hour,news_image,news_image_peq,categoria) VALUES('$news_title','".$_POST["news_subtitle"]."','".$_POST["news_desc"]."','".$_POST["news_post"]."','".$_POST["news_date"]."','".$_POST["hour"]."','".$_POST["news_image"]."','".$_POST["news_image_peq"]."','".$_POST["categoria"]."')"; Ofc, for every value you send to MySQL.

You can store the files on your server temporarily and then use getimagesize.

Counting number of columns with the same number
cataiin replied to therocker's topic in PHP Coding Help
I tried the code on localhost first time and I was wrong when I changed the values. Sorry! He just needs to modify the first count with forums_id in my code. -
I can't edit my post. Try this: <?php $image = "http://forums.phpfreaks.com/uploads/profile/photo-thumb-165140.jpg"; if(@getimagesize($image) !== false) { echo "<img src=".$image." />"; } else { echo "Nop."; } ?>

Link for image?

SELECT count, count(*) as forums_counting FROM forums_comment WHERE forums_id = '$forums_id' GROUP BY forums_id -
You can use $_GET['id]; in item.php page to get item.php?id=1 (content from current item1.php) and then with RewriteRule: RewriteRule ^([0-9]+)$ /item.php?id=$1 Ask if you have more questions.

I want to use RewriteRule two times, first to change /page.php?id=1321 to /1321 and second to change /search.php?text=ab aa&page=2 to /search/ab--aa/2 but I don't know how because it has two queries (text and page). Until now, I have this: RewriteEngine On RewriteRule ^([0-9]+)$ /page.php?id=$1 Also, I want (if it's possible) to allow only letters (uppercase and lowercase) and spaces for text and transform spaces in - or _, and for page I want only numbers. I've tried with: RewriteRule ^(.+)/(\d+)$ /search.php?text=$3&&page=$2 [L] But isn't working and I'm pretty sure it will not accept just what I want..

More than perfect! Thanks!

No idea about fixing with preg_match? Or anything else... Ty!

Don't work. Notice: Trying to get property of non-object in www\index.php on line 10 Probably because the string comes from external URL.

321313-0381","something":"value,"

Hi guys. I have this "sentence": "key":"321313-0381","something":"value," and I want to obtain only 321313-0381. The problem is somethings differs, isn't always the same. I've tried: $start = '"key":"'; $end = '","'; preg_match("/$start(.*)$end/s", $content, $match); $result = $match[1]; echo "$result"; But unsuccessful. For $end = '\/'; too. Can I get a little help?

I have this code: <?php $url = "http://www.example.com/"; $page = fopen($url, 'r'); $content = ""; while( !feof( $page ) ) { $buffer = trim( fgets( $page, 4096 ) ); $content .= $buffer; } $start = "<text1>"; $end = "<\/text2>"; preg_match( "/$start(.*)$end/s", $content, $match); $mytext = $match[1]; echo "$mytext"; ?> Now, I need a way for users to enter $url. I've tried with $_GET and to get current url (something like index.php?url=$url) but unsuccessful.
