PHP - Php - Splitting A Piece Of Text?
Hello,
I have a variable that holds a piece of text that looks something like this: "world,blue,big". Is there anyway to split the text into the separate words as an array, and remove the commas? Code: [Select] $text_to_split = "world,blue,big"; $splitArray = array(); //Do some kind of php function that splits text\\ echo splitArray[0]; // world echo splitArray[1]; //blue echo splitArray[2]; //big Would appreciate it, thanks Similar TutorialsI’m trying to construct a button that simply writes an "aleph" character into a text area, see below.
My code does not work, can anyone tell me why ? How should I fix it ?
<!DOCTYPE html>
<html>
<meta charset="UTF-8">
<head>
<title>Example</title>
<script type="text/javascript">
//JavaScript code goes here
function insertAtEnd(text)
{
var theArea = document.getElementById("thisArea");
theArea.value += '' + text + '';;
}
</script>
</head>
<body>
<input type="button" id="aleph" name="aleph" value="Write an aleph"
onClick="javascript:insertAtEnd(\'<span>א</span>\');return(false)" />
<textarea id="thisArea"> </textarea>
</body>

I have a text field that contains the following (example text used): 1 2 3 4 5 6 As you can see the first few are split by a single space, with the last few numbers split by a double space. My aim is to put each of these numbers into a table in a MYSQL database. But I'm having trouble breaking them up. Hi Guys, does anyone know how split a text into groups depending on how many words are in the text e.g $text = "If you are new to PHP and want to get some idea of how it works, try the introductory tutorial. "; I want a maximium of 5 words in each group, so the above text will be split as such $text1 = 'If you are new to'; $text2 = 'PHP and want to get'; $text3 = 'some idea of how it '; $text4 = 'works, try the introductory tutorial.'; But if I want a maximium of 10 words in each group, so the above text will then be split like this $text1 = 'If you are new to PHP and want to get'; $text2 = 'some idea of how it works, try the introductory tutorial.'; $text3 = ''; $text4 = ''; Is this possible? Please any help will be much appreciated thanks hi, how is everybody doing? i hope well, i have a problem with some php code. i am trying to split some text in two parts once they have been split, they are display, but sometimes the php code break the source code of the page such as images and instead of the image i get the source code like this Quote add-plugins-paintnet-1.2-800x800 3857cff9733e6a.jpg" style="border-width: 1px; border-color: #000000; border-style: solid; margin: 4px auto 5px; display: block;" /> i have tried for about 2 days now to fix it and i haven't been able to, so any help or guidence would be greatly appreciated. this is the code that i am currently using, i have tried to change the variable in the $findTag but nothing seems to work Code: [Select] <? php $article =$this->article_>text; $countchars=strlen($article); $divide=$countchars/2; $firstpart=substr($article,0,$divide); $secondpart=substr($article,$divide); //i keep changing the <p /> variable to <img /> and $image and many others but nothing seems to work $findTag = strpos($secondpart, "<p /> "); $var = $divide + $findTag $firstpart = substr($article, 0, $var); $secondpart = substr($article, $var); ?> thanks Hello, I have a long list of webpage addresses like this which extends below the fold / the bottom of a user's screen: Webpage 1 Webpage 2 Webpage 3 Webpage 4 Webpage 5 Webpage 6 Webpage 7 Webpage 8 Webpage 9 Webpage 10 Webpage 11 etc... I want to take this long list of words and split them into columns so that the reader never has to scroll down. Please can you tell me the best way of going about this? (should I just design for a specific screen resolution? - if so which screen resolution should I design for?). Many thanks, Stu Hello,
I'm working on a project that requires me to have stock / fake demo files that will be replaced with real files provided by users... I need something to take space and then when people actually start using the site and inputting data, then I can replace each file with new, unique files.
I have some idea of how this would work.
I would need incremented or non-matching identifiers and then a script that probably works on an if statement
like
If new data, take first list of data, delete, replace with new data. Something like that.

Can anyone help me out with this!? :'( BR Vixus Hi there, Sorry if this is the wrong forum to post this in, If it is please feel free to move it to the correct one. I have a php page and I am trying to get a couple of lines to only be run if Javascript is disabled on the visitors browsers. Code: [Select] $returnpage = 'myphppage.php'; include('anotherphppage.php'); It is something probably simple but I can't see it... I have tried: Code: [Select] <noscript> <?php $returnpage = 'myphppage.php'; include('anotherphppage.php'); ?> </noscript> but that does not seem to work and I was hoping someone here would have an idea... Many thanks in advance Ross
Hi there, i have an code <?php $a = [ 0 => 10, ]; $i = 0; $a[$i++] = $i;
and question "Explain what the problem is and what you could do to fix it"
Please help! Hi guys, I apologize for the number of posts regarding this particular class that I am writing (really, at this point, you've probably done more in it), but I have another issue. I've decided to re-write the pieces that were giving me trouble, and instead of using a for loop, I went to a foreach loop. Here's what it in the database for the particular query: Here's what I get when I dump the array with print_r(): Array ( => Array ( [0] => 4 [id] => 4 [1] => Test [label] => Test [2] => ?r=test [link] => ?r=test [3] => [relation] => [4] => 0 [parent] => 0 [5] => 5 [sort] => 5 [6] => 1 [active] => 1 ) [1] => Array ( => 2 [id] => 2 [1] => About Us [label] => About Us [2] => ?r=about [link] => ?r=about [3] => [relation] => [4] => 0 [parent] => 0 [5] => 10 [sort] => 10 [6] => 0 [active] => 0 ) [2] => Array ( => 3 [id] => 3 [1] => Fleet [label] => Fleet [2] => ?r=about/fleet [link] => ?r=about/fleet [3] => [relation] => [4] => 2 [parent] => 2 [5] => 0 [sort] => 0 [6] => 0 [active] => 0 ) ) And the SQL statement: SELECT * FROM `menu` ORDER BY `parent` ASC, `sort` ASC With the corresponding PHP code (The issue starts in formatMenuItems()): Code: [Select] <?php /** * Menu Class * * This file is used to create a dynamic menu based on the user's permissions and status * @author Max Udaskin <max.udaskin@gmail.com> * @version 1.0 * @package navigation */ /** * @ignore */ if(!defined('ALLOW_ACCESS')) { // Do not allow the file to be accessed by itself die('Restricted File.'); } require_once("Database.php"); class Menu { protected $login; protected $all_rows; protected $menu_items; protected $html = NULL; /** * The constructor * @param Login $login */ function _construct() { } /** * Get All Items * Retrieves all database menu items */ private function getAllItems() { $sql = 'SELECT * FROM `menu` ORDER BY `parent` ASC, `sort` ASC'; $database = new Database('default'); $database->connect(); $database->fetchArray($sql); $query = $database->getLastQuery(); $i = 0; while($row = mysql_fetch_array($query)) { $this->all_rows[$i] = $row; $i++; } print_r($this->all_rows); } /* * Selects the menu items that are appropriate for the user */ private function chooseMenuItems() { $this->menu_items = $this->all_rows; } /** * Formats the menu items for the HTML output */ private function formatMenuItems() { $menu = array(); $menu_imploded = ''; foreach($this->menu_items as $item) { if($item['parent'] == 0) { $menu[] = $this->parseItem($item); } } $menu_imploded = $this->combineMultiArray('', $menu); echo '<div id="menu">'; echo $menu_imploded; echo '</div>'; } /** * Searches an array and it's sub arrays for a defined value ($for) * @param array $array * @param mixed $for */ private function search(array $array, $for) { foreach ($array as $key => $value) { if ($value === $for) { return ($key); } else if (is_array($value)) { $found = $this->search($value, $for); if (is_array($found)) { array_unshift($found, $key); return $found; } } } return false; } /** * Gets the array item and returns it * @param array $arr * @param string $string */ function variableArray($arr, $string) { preg_match_all('/\[([^\]]*)\]/', $string, $arr_matches, PREG_PATTERN_ORDER); $return = $arr; foreach($arr_matches[1] as $dimension) { $return = $return[$dimension]; } return $return; } /** * Parses HTML for the item, as an array * @param array $item */ private function parseItem($item) { if($item['parent'] == 0) { $h2_s = '<h2>'; $h2_e = '</h2>'; } else { $h2_s = ''; $h2_e = ''; } $return[0] = '<ul><li>' . $h2_s .

This piece of code he $query .= " limit $s,$limit"; $result = mysql_query($query) or die("Couldn't execute query"); is part of my search results page with paged indexes (next, previous 10, etc.). However with this code i get the die message but if i take the first line off ($query), the page executes but then the page doesn't operate correctly i.e. shows 15 results when the $limit(limit for rows) =10. Is it not written correctly or am I missing somethingwith the top line? if the entire script is needed let me know and i will paste it? Thanks in advance for any help!

For example, the following examples of passing by reference are invalid: <?php function foo(&$var) { $var++; } function bar() // Note the missing & { $a = 5; return $a; } foo(bar()); // Produces fatal error since PHP 5.0.5 foo($a = 5); // Expression, not variable foo(5); // Produces fatal error ?> So, i decided to try it out myself like i always do, and i noticed that i'm not getting an error when i do foo(bar()); i.e calling bar() without the & in the function declaration. Infact it works perfectly fine and returns an incremented $a after its passed to foo(). Likewise foo($a = 5); also works great and returns an incremented $a after being passed to foo(). Is this a mistake in the manual or am i missing something? Running PHP 5.3.2-1ubuntu4.5 Heya guys! What's up? OK here's my problem: I got a variable, $var1, which is to have values like "groan,100,200,350,50" I need to know how to split this $var1 into $split1, $split2, $split3, $split4, $split5, where $split1 = "groan"; $split2 = "100"; $split3 = "200"; $split4 = "350"; $split5 = "50"; Thanks in advance people! P.S. In my case I am going to use some of the values for calculations. So I don't think that its easy with arrays, which are difficult for me to understand . P.S.S. When I am retrieving data from the database, many variables like $var1 that need to be split are being extracted. I hope that you understand. Thanks and Regards, Thauwa http://mobsters-fb-apache-dynamic-lb.playdom.com/mob_fb/get_hit_list?user_id=100000952273457&target_id=100000556624340&level=300&auth_key=cb07c7575b38df48d82dd53619385faa884db5a2 When going to this URL, it gives entries between <entry> and </entry>, what I am trying to do, is collect the <user_id> ONLY if the <amount> is over a certain value. Any ideas to how I could do this (I am a complete PHP noob). All help is appreciated Hi, I am trying to translate a page in PHP using Google API. There is 5000 chars limit on data that you can send to Google at a time. So I am trying to break the page into pieces of 5000 chars. But as you know while doing this we have to keep in mind the HTML formatting that it should not be disturbed otherwise you will not get desired results. For example you have to send this: <a href="#" class="myclass">Link</a> Instead of this: <a href="#" class="myclas I am able to solve it somehow (although not perfectly I guess) by checking if "<" sign is coming after ">" sign or not. If "<" sign is coming after ">" then I go back to the point where I found ">" and cut string from there. Anyway the point is I am still having some problems regarding HTML formatting and want to know how to do it efficiently. Is there any parser available that will solve this problem!? Thanks |
