PHP - Preg_match_all Fails If New Line Present

This is rather bothering as I know if you use the delimiter / regex pattern s it should ignore newlines


 preg_match_all("%<p><b>(.*?)</b>%s", $html, $data);


Returns a blank array
the page data is like so

<p>

                        <b>41,910</b><br/>
                        Total Points
                    </p>

Never had a problem before that i can recall but for some reason with this page it's giving me issues. Maybe i'm missing something?

Hello all!  So I am working on screen scraping a site for my son's rec league.  I seem to be having problem with the pre_match_all syntax.  Here is my code

Code: [Select]

<?php

$url = "http://www.mywebsite.com";
$raw = file_get_contents($url);

$newlines = array("\t","\n","\r","\x20\x20","\0","\x0B");
$content = str_replace($newlines, "", html_entity_decode($raw));

$start = strpos($content,'table border="1" cellpadding="1" cellspacing="0"');
$end = strpos($content,'</table>',$start) + 8;

$table = substr($content,$start,$end-$start);

preg_match_all("|<tr(.*)</tr>|U",$table,$rows);
foreach ($rows[0] as $row){

    if ((strpos($row,'<th')===false)){
    
        preg_match_all("|<td(.*)</td>|U",$row,$cells);
        
        $game_date = strip_tags($cells[0][0]);
        
        $game_time = strip_tags($cells[0][1]);
        
        $rink = strip_tags($cells[0][2]);

$home_team = strip_tags($cells[0][3]);

$home_score = strip_tags($cells[0][4]); 

$visiting_team = strip_tags($cells[0][5]);

$visiting_score = strip_tags($cells[0][6]);
           
echo "{$game_date} @ {$game_time} : [{$home_team}] - {$home_score} vs. [{$visiting_team}] - {$visiting_score} <br>\n";

    }

}

?>

My issue is that I am trying to get it to only display the data if the team name = x.  I tried to replace the   preg_match_all("|<td(.*)</td>|U",$row,$cells); with   preg_match_all("|Posse|U",$row,$cells);   (Posse is one of the team names).   No luck. 

Any input/thoughts?!  Thank you!!

Hi there i have this code:
Code: [Select]
$str = "<i><font color="800080"> man </font></i><p><font color="9898989"> hi </font></p><p><font color="1111111"> cheers </font></p>";
$pattern = '/<font .*?>(.*?)<\/font>/';
if(preg_match_all($pattern, addslashes($str), $posts)){
        $i=0;
for($i; $i < count($posts[0]); $i++){
            echo "content: " . $posts[0][$i] . "<br/>";
            echo "colour: " . $posts[1][$i] . "<br/>";
             echo "<br />";
           
           }
}
and it doesn't work apparently because of the addslashes but its really needed as double quotes needs to be escaped, consider that i'm applying this code to a larger html file with hundreds of double quotes to be escaped....

error msg i get is Parse error: syntax error, unexpected T_LNUMBER in
thanks in advance..

I have noticed that if I run the preg_match_all function and use PREG_OFFSET_CAPTURE option to start capture somwhere in the middle of the string the second half of the string will be searched first returning the matching sections along with positions, then it goes up to the top half and returns matches from there too.
Is there way to parse only between start point and end of string?

I am trying to use preg_match_all to find some information on a webpage.

Here is what I am currently using

<?php
$homepage = "http://www.example.com";
$page_contents1 = file_get_contents($homepage);
$names1 = preg_match_all('/<span class="video_date">(.*)</span> - <a class="b" href="/(.*)/">(.*)</a><br/>\/', $page_contents1, $matches1);
echo implode(", ", $matches1[1]);
?>


I am trying to match this piece of html:
<span class="video_date">Oct 21</span> - <a class="b" href="/meanwhilezealand/">   Meanwhile in New Zealand...</a><br/>

Thanks for looking!

Hi,

 

I have made a database linked with php that I use a html form for.

The HTML form requests a particular date to retrieve, and the php form it is linked to then retrieves data from the MySQL database from that date.

 

My question is: I want there to be a restriction so that the retrieval can only be for dates before the present date (and certainly not any date in the future).

 

e.g. if it is 6th July 2020, then the database can only retrieve from the 5th July 2020 and before. (7th July 2020 onwards also is not allowed.)

Is there a way I can do it? Anyone who can guide me to a particular code function or something of that sort - I would be deeply grateful as my searches have not come up fruitful.

Hi, guys.

I want to present different ads to visitors in different countries.  For example, if a visitor is in Australia, I want him/her to see a different ad from, say, a visitor from the UK. Can this kind of thing be done with PHP? If so, will installing such a code slow down my site?

Any help will be appreciated very much.

Hi,

I have the following code in a WordPress theme which displays a companies website, Twitter and Facebook links.

What I am trying to do is display the text "Useful Links:" if one of the links exists, and hide the text if all are not present.

<p>Useful Links:</p>
<?php if ( $website = get_the_company_website() ) : ?>

                            <a class="company-website" href="<?php echo esc_url( $website ); ?>" itemprop="url" target="_blank" rel="nofollow"><?php _e('Website', 'jobseek'); ?></a>

                        <?php endif; ?>

                        <?php if ( get_the_company_twitter() ) : ?>

                            <a class="company-twitter" href="http://twitter.com/<?php echo get_the_company_twitter(); ?>"  target="_blank"><?php _e('Twitter', 'jobseek'); ?></a>

                        <?php endif; ?>

                        <?php
                        $facebook_link = get_post_meta( get_the_ID(), '_facebook_link', true );
                        if ( ! empty($facebook_link) ) : ?>
                            <a class="company-facebook" href="<?php echo $facebook_link; ?>"  target="_blank">Facebook</a>
   <?php endif; ?>

What would be the best way to show/hide the text depending on if the items are present or not?

Thanks

Hi all

I have a MySQL data base that is saving information from a form. One the form a user can add a business name which is text and a logo if they have one.

Now on my web page I want to beabe to display the picture if present if not I would like it to display the business name. How do I do this please. I know how to conect to DB etc just having problems getting my head around this problem.

I have code:
$proname1 = preg_match_all('/<div class=("|\')agentContainer("|\')>(\n\s)<div class="strong">(\n\s)(.*?)(\n\s)<\/div>/', $html, $name1);()
Which is putting everything between these tags into an array, but the info contains new lines and whitespace, thus displaying empty entries in the array. How do I strip the whitespace and newlines prior to getting to the array? The data Im getting looks like...

Code: [Select]
<div class="agentContainer">
<div class="strong">
Blah Blah Company
</div>
And blah blah company isnt showing up in the array, but I know the regex is working.

Hi,

I have the written the following code which scrapes price info from a website:

$url = 'http://www.mydomain.com';
$html = file_get_contents($url);
$pattern = '/<span class="price">(.*?)<\/span>/';
preg_match_all($pattern, $html, $matches);
print_r($matches);

It works well however I need to add in the delivery cost to each array element with a different pattern:
/<span class="delivery">(.*?)<\/span>/';

Any idea how i can do this so each array element has both the price and delivery costs in a two dimensional array?

Thanks for your advice

For example.

I have the following:

Andrew (Age 19)

How would I get the content between the brackets, Age 19 using preg_match_all or a similar function?

Thanks very much
