PHP - Find String In Text

I need to find first digit (any number 0 - 9) in a string.
I thing I should be able to use:
$NumberPosition = strpos($Source, "/[0-9]/", $NumberPosition+1);
but it does not work, wonder what I am doing wrong?

Is there an easy way to find a numeric value in a string if I don't know what the string will contain?
For example I want '52' out of: mystring52

Hopefully there is already a simple function to do this? I'm thinking there may not be as the string having more than one group of numbers may confuse matters. I'm just dealing with abcdef123 or similar in this case though.

if i want find included a word in the a range how can i do it?

example : Quote

array("problem is an obstacle, impediment, difficulty or challenge, or any situation that invites resolution; the resolution of which is recognized as a solutionquestion raised for inquiry, consideration, or solution proposition in mathematics or physics stating something to be done");



how can i find only start 20 charecter and my found word after 20 character by end

example :if my word be inquiry

i want find :...soluti

Quote

onquestion raised for inquiryconsideration, or solution proposition...

I have another question related to string searches.
What I have is a string of couple thousand characters of all types but the date format is allways the same: dd-mth-year (two digits for day-three letters for month-four digits for year). Can I use the format alone to determine where the date is located which in turn would make it very easy to store that date into variables for inserting into database, etc.
Is there anyway to tell php the format to look for or do I have to have actual numbers/letters to perform the search?

Hello everyone,

I am trying to select and return any rows that have a specific string in it.
Let's say I have a column name "item_id" and in every row of that column I have values like so:

row A: (11,22,44,34)
row B: (12,56,78,98)

If the user picks the number '22', I use the following SQL line to get the row in which the number '22' is contained.

SELECT * FROM Persons WHERE City LIKE '%22%'
and row A gets returned, just like it is suppose to.

The problem is, if the user selects a single digit number like '2', both row A and row B gets returned because they both have values that contain the number '2' in it.
Instance, row A has the number '22' and row B has the number '12' so both rows get returned when the number '2' is requested. I don't want that, I only want the row that has the exact number '2' or '34' or whatever number I request, to be returned.

So to get around this problem, I am wrapping my numbers in letters like so:

row A: (a11a,a22a,a44a,a34a)
row B: (a12a,a56a,a78a,a98a,a2a)

and requesting it like so:

SELECT * FROM Persons WHERE City LIKE '%a22a%'
My question is: Is there a better way to work out this logic?

Is it pasible to find all occurrences of strings "North" and "North-East" in some txt file and save number of occurrences in some variables??

Hi I have a MySql database and wondered if there is a code to search a table field with a given string and display the number of unique occurrences. The table is asterisk_cdr and would like to know how many calls received daily on a perticular channel.   Thanks shmideo  

Hello,

I have a few strings that contain dates along with some other text.
The string looks like this:

Code: [Select]
Hi, could you please add these dates to the database?<br />
 <br />
<br />
2-September-2011<br />
6-September-2011<br />
7-September-2011<br />
8-September-2011<br />
9-September-2011<br />
 <br />
Thank you.

Dates are always the same format. Sometimes there's a single date, most times there are multiple.
Does anyone know how can I get the dates from this string to add them to my sql database?

Thank you!

Hi All,

I'm new at php and I need your help.

I'm trying to find a string in a website. I want my website to get a string on another website(I have full access) without really opening it on a browser. For example the string is "MyID=123456", i want to find "MyID=123456"(the MyID number is random and always changing but always 6 random numbers) on another website and output only "123456" on my website. Is this possible?

Please help. Thanks

thank you

Hi, Everyone!

I have an issue and I'm not even sure if it can be done with PHP, but even this info would help me (to stop looking for an answer).

I need to populate a (MySQL) database with stuff which is now written in a (HTML formatted) file. Here are my options:
1. Copy/paste each single field via PHPMyAdmin .
2. Write a little script to extract the necessary parts of text from these files to create a CSV-like content which I would then easily INSERT into the db.

Example
The files look like this:

Code: [Select]
<!-- SEPARATOR (same throughout the file(s) -->

<tr><td>

<div style="something"><img src="img/what_i_need_to_extract_1.png"></div>

</td><td>

<div style="something else"><b>What I need to extract 2</b></div>
<div style="something else">What I need to extract 3</div>

</td></tr>

<!-- SEPARATOR (same throughout the file(s) -->
etc ...
and it goes like... 100 times in each file in the same standard pattern with the "What I need to extract" parts being completely different each time.

Since it's possible to tell when each part required for extraction begins and ends, I would expect the script to look for these key-points (according to the example, it would be: img/ to  "></d then "><b> to </b>< and else"> to </div>) and return a result like this (acc. to the example): ('what_i_need_to_extract_1.png', 'What I need to extract 2', 'What I need to extract 3'), (and so on...).

Is it possible? Is there a function/option/way to look for a start/end-point like this and fetch the part between these two set points? If so - how? Any help would be appreciated, I'm not expecting a full code, obviously, just a point to the right direction or where to look at would be nice. Thanks in advance.

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]";
      }
   }
}

?>
