PHP - Help Finding A Matching Word Within A Phrase Of Text. Using A String.
Hi, and thanks for any help with this.
I have this but of php i have been trying relentlessly to get working.. for over a month.
<?php
$abs="one two three four words";
$mT = "testing for matching words";
$words=explode(' ', $abs);
//$sf=($words);
if (preg_match($words, $mT))
{
echo "the url $mT contains a Word";
}
else
{
echo "the url $mT does Not contain a Word";
echo "$words[4]";
}
?>
You see, I get a responce only using the last line "$words[4]", (obviously, because I am pointing it the Matching word, (ie: with [4]) Edited June 9, 2020 by x1705 better description. Similar TutorialsFolks, I want to find a Word in a string. If the word is found, i want to retrun TRUE else FALSE. $string: Sol 3 Drawer Chests Antique Pine Bedside Chest $word to be found: Chest Now the tricky part is: In the $string the $word occurs twice once its CHESTS (i mean the first occurance) then CHEST. If its found, i want to return TRUE else FALSE. I tried using strpos() but it just checks for CHEST and not CHESTS. How can it be achieved? Cheers Natasha for example, i want to search for an the string "example@example.com" and erase it. thanks in advance !
Hi, simply put;
$abs="Bob Rob Sue";
how can I put into code, when "Bob1:2" is used, it finds a match of "Bob", and assigns the complete string of "Bob1:2" ?
<?php
$abs="Bob Rob Sue";
$abby="sometext Bob1:2 is Sue3:4 where Rob2:1 etc";
$nums = preg_replace('/[a-zA-Z]/', ' ', $abby);
$lets = preg_replace('/[0-9]:?[^0-9]/', ' ', $abby);
//$lets1=array_intersect($abs, $lets);
$absArr = explode(' ', $abs);
$abbyArr = explode(' ', $lets);
$letsx=array_intersect($absArr, $abbyArr);
//echo $letsx[0] . "</br>";
//#############################################
$nums1='/(\d+\:\d+)/s';
preg_match_all($nums1, $nums, $nums2);
foreach($nums2 as $numsx){
}
$abi0="$letsx[0]+$numsx[0]";
$abi1="$letsx[1]+$numsx[1]";
$abi2="$letsx[2]+$numsx[2]";
$answer=$abi0."</br>".$abi1."</br>".$abi2."</br>";
echo $answer;
?>
current results: Here we go, I need to use a query where it uses a posted time value to compare if there are the same times on the posted date value. I want it so the user cant book the same time on the same day as someone before bascially.

Hello All, I've been knocking my head against the wall for several hours trying to figure out what's going on with a simple string replace. For the most part it is working beautifully, but if a string contains a similar but not exact match it still replaces the non match. I was under the impression that str_replace always looks for an exact match. I have custom tags that are in strings of text that are structured like: [A_CUSTOM_HEADER] [A_CUSTOM_TITLE] and so on. They always start with "[A_CUSTOM" and end with a " ] ". In between the start and end can be just about anything. So my problem is if I have [A_CUSTOM] and [A_CUSTOM_TAG] in the same text str_replace seems to incorrectly replace all the [A_CUSTOM_TAG] with the [A_CUSTOM] content and the match never happens for the [A_CUSTOM_TAG] content. For example:
$content = 'Here is some text and [A_CUSTOM]. Here is more text and [A_CUSTOM_TAG]'.
$content = str_replace('[A_CUSTOM]','I have a and custom',$content);
$content = str_replace('[A_CUSTOM_TAG]','I have a, custom and tag',$content);
So running that code The [A_CUSTOM_TAG] content never gets replaced correctly, it is replaced on the first pass with the [A_CUSTOM] replacement content. I hope this make sense I'm trying to explain it the best I can. I tried using preg_replace() with \b to match the whole word but didn't get anything close to the respected results...haha I'm sure I'm missing something simple...or at least I hope I am. Thanks in advance! Edited by Twitch, 22 May 2014 - 11:52 AM. I am looking for a date within larger string, lets say the date is December 4, 2010. To find it I use pattern and function below: $Pattern='/[(January|February|March|April|May|June|July|August|September|October|November|December)] \d, \d\d\d\d/i'; preg_match_all($Pattern, $String, $Matches, PREG_OFFSET_CAPTURE, $NumberPosition); The function finds the dates within the string but to my supprise the result I get in $Matches is: r 4, 2010 What I would like to get is: December 4, 2010 but don't know how it should be fixed. I thought that with the pattern I am using but obviously that is not the case. I need to know if a string exists within a string. I've tried using STRIPOS() but it returns zero or false if what I'm looking for is the first part of the string. I don't care what function I use, but I need to get a "true" when the needle string is present anywhere in the haystack string, even at location zero. Is there some way to set up the STRIPOS() statement? I've tried: if ((stripos($title, 'needle') > 0 ) if ((stripos($title, 'needle') = true ) and even if ((stripos($title, 'needle') >= 0 ) which returns true for everything, even when the needle string is NOT present. Any help appreciated. thanks, Tom I have a web server which contains a public site and a private site. I want to be able to test for public or private using the page title and return the appropriate header which contains a different banner, css etc. Firstly - the syntax below seems to be incorrect because it doesnt work correctly. More importantly how do I add all the values to an array and than iterate through it to check for a matching page title? Code: [Select] public function publicSite() { if ($this->getTitle()== 'Home' || 'About Us'||'Registration' || 'Sitemap' || 'Contact Us' || 'Useful Links' || 'Feedback') { return true; } return false; } Then later on I would have: Code: [Select] if ($this->publicSite()) { require($ROOT.'interface/pages/publicheader.php'); } else { require($ROOT.'interface/pages/privateheader.php'); } Thanks heaps! I am trying to find a character in the follwing string $string = ' Mumbai Mast Kallander - 02 - Mumbai Mast Kallander'; the character i want to find is '-' and the find how many times does it occur in the string.. can anyone help? This topic has been moved quickly to PHP Regex because I need to go to work instead of lurking phpfreaks. http://www.phpfreaks.com/forums/index.php?topic=359460.0 %3$s displays a string of text that always begins with a number followed by a colon (from 1-25 only). 1: 2: 3: etc... Is there a way to remove the number and the colon entirely and leave the rest of the string intact? Code: [Select] function wp_rss( $url, $num_items = -1 ) { if ( $rss = fetch_rss( $url ) ) { if ( $num_items !== -1 ) { $rss->items = array_slice( $rss->items, 0, $num_items ); } //start count $i = 1; foreach ( (array) $rss->items as $item ) { printf( '<div title="%2$s"><strong>'.$i.'</strong></div><div>%3$s</div>', esc_url( $item['link'] ), esc_attr( strip_tags( $item['description'] ) ), htmlentities( $item['title'] ) ); //increment $i++; } Ashley I have a DB of data: article-id, section-id, subsection-id, article-text. When a row is fetched I am displaying article, section, subsection as <h3>, <h4>, <h5> and then text in a <p>. Before outputting the text I want to scan it for other articles, sections, or subsections it may reference then turn that reference into a hyperlink. I read the PHP documentation but I can't find anything that translates to the basic commands of instring, indexof, and left/mid/right. Example: 1. Article Name 100. Article 1, section 1 100.a article 1, section 1, subsection a Text blah blah blah 105.f blah blah blah
I want to find that 105.f and turn it into a link. All my articles, sections, and subsections are in the DB so I know I can use an array of the number values as my items to look for, but I can't figure out how to look. I want to catch the first word of a string in which the words are separated by "-" (e.g. "first-word-second-one-more"). I used this code: $string = explode('-', $string); echo $string[0]; The problem is that when the string contains only one word, it returns null Whats the quickest way to find a word in a string and wrap <b> tags around it? Code: [Select] $search = "php web"; $striing = "PHP is the web scripting language of choice"; Basically im looking for the output to be : "<b>PHP</b> is the <b>web</b> scripting language of choice" There are many ways to delete everything after a character in a string. I am looking for a simple way to delete everything after a given word. I have been becoming more and more familiar with PHP over the past few months, but this problem stumps me. How can I take a string of words separated by spaces taken from an XML feed (example: word1 word2 word3 word4) and turn it into something like this: <a href="word1">word1</a> <a href="word2">word2</a> ... and so on. This has to be done on the fly, since it is taking the words from the XML feed, they change depending on the page. I want them to be in a vertical column, and be able to link each one to the search page for that word, so each link has to be different. An even more in-depth problem, how can I sort it then so that there are multiple columns if necessary, say one page only has 3 words, but another has 50. How can I split them up into multiple vertical columns, say with 10 words in each? Have I confused anyone yet? How could I split a string in half but not in the middle of a word? $information = "This is the string of text, however at some point in the sentence a word may get split in half."; $cut = round(strlen($information)/2); ///where to cut (50%) $split1 = substr($information, 0, $cut); //first half $split2 = substr($information, $cut); // second half i am making a search engine to search my site and the code is going well but i don't know how to find your search within the results and put it in bold (like google does). I use a thing called http://simplehtmldom.sourceforge.net/ for getting the html of my website. Code: [Select] <?php include('simple_html_dom.php'); ?> <?php $s = $_GET["s"]; if ($s == null) echo "you have not searched for anything"; else echo "you searched for $s<hr>"; $urls[0] = 'http://url.com/'; $urls[1] = 'http://url2.com'; foreach ($urls as $url) { $html = file_get_html($url); strip_tags($html); preg_match("/<body>(.*)<\/body>/s", $html, $body); $htmls_split = split('<', $body[1]); foreach ($htmls_split as $line) { if (preg_match("/$s.*/", $line, $matches)) { echo "<p>$matches[0]"; } } } ?> |
