PHP - Removing Search String

hi im having trouble removing ' from strings    so say  $name = "D'vion";   $newname = str_replace("'","",$name);   but this just returns the same.   thanks matt

Hey guys! I found a flush function and it seems to be working well, but sometimes it will cut off characters. It's very strange.

Here's my flush function: function out($str) {
echo $str."<br />\n";
vbflush();
}

function vbflush() {
if (ob_get_length()){           
@ob_flush();
@flush();
@ob_end_flush();
}   
@ob_start();
}And I'm calling it like this:out('Waiting 30 seconds until execution');And this is my output: Code: [Select]
Waiting 30 seconds until executioAnyone know why?

%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++;
}

In <div id="chart_rt">%3$s</div> below, it is populated with a string that always begins with a number followed by a colon (from 1: to 25:). I see that ltrim removes characters from the beginning of a string but I don't see how to compensate for the extra character in 10: through 25:


function wp_rss( $url, $num_items = -1 ) {
    if ( $rss = fetch_rss( $url ) ) {
        echo '<div id="charts">';

        if ( $num_items !== -1 ) {
            $rss->items = array_slice( $rss->items, 0, $num_items );
        }
//start count
$i = 1;
        foreach ( (array) $rss->items as $item ) {
            printf(
                '<div id="chart_lt">'.$i.'</div><div id="chart_rt">%3$s</div>',
                esc_url( $item['link'] ),
                esc_attr( strip_tags( $item['description'] ) ),
                htmlentities( $item['title'] )
            );
//increment
$i++;
        }

        echo '</div>';
    } else {
        _e( 'An error has occurred, which probably means the feed is down. Try again later.' );
    }
}

Hello,

Any help would be great. I'm filtering and rss feed and to create a new feed with some <item>'s removed. Here is a snippet from the source file.

<item>
   <title><h1>Indians, Pacers and Colts attendance is only part of story</h1></title>
   <link>http://www.newsweek.com/the-score/2010/07/29/indians-pacers-and-colts-draw-similar-sized-crowds/PARAMS/post/21385</link>
   <description></description>
</item>   

<item>
   <title><h1>Declining attendance forcing Speedway to make changes</h1></title>

   <link>http://www.newsweek.com/declining-attendance-forcing-speedway-to-make-changes/PARAMS/article/21369</link>

<item>
   <title><h1>Three issues that could derail Indy's 2012 Super Bowl</h1></title>
   <link>http://www.newsweek.com/the-score/2010/07/27/three-issues-that-could-derail-indys-2012-super-bowl/PARAMS/post/21341</link>
   <description></description>
</item>   


I'm wanting to use the link tag to detect the item that need to be removed for the new rss feed. All <item>with <link> that contain http://www.newsweek.com/the-score/ as the beginning of the link need to be filtered out.

Here is my code so far.

<?php echo '<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:media = "http://search.yahoo.com/mrss">
   <channel>
      <title>CLE Calendar</title>
      <description>CLE Calendar</description>
      <language>en-us</language>
      <pubDate>June 14, 2010</pubDate>
      <lastBuildDate>June 14, 2010</lastBuildDate>
      <ttl>15</ttl>'; ?>


<?php $rss = new SimpleXMLElement('http://www.newsweek.com/mobile-app/rss/feed?rssId=18&premium=false', null, true); ?>

<?php foreach ($rss->channel->item as $items): ?>

<item>
   <title><?php echo '<h1>' . $items->title . '</h1>'; ?></title>
   <link><?php echo $items->link; ?></link>
   </item>   
<?php endforeach; ?>
</channel>
</rss>

Thanks in advance,
MK

Hello, I have this XML file I am parsing and I have hit a small formatting issue that I can't seem to get around.    Here is what the the output of the RSS looks like. 

<description><![CDATA[<div style='text-align:left;'>Exit ramp closed. <br/><b>Current Status:</b> Open<br/><b>Affected Lanes:</b> Exit Ramp<br/><b>Dates:</b> Wednesday, May 28 - Thursday, May 29<br/><b>Days Closed:</b> <font color='#808080'>S</font><font color='#808080'>M</font><font color='#808080'>T</font><font color='#FF0000'><b>W</b></font><font color='#FF0000'><b>T</b></font><font color='#808080'>F</font><font color='#808080'>S</font>&nbsp;&nbsp;&nbsp;20:00 PM - 6:00 AM</div>]]></description>

Notice at the first is "Exit ramp closed." There is nothing before it but, for some weird reason when I parse it. It is on a new line like so, notice it should be up there with "Incident" but, it is dropped down below it. 

Incident:
Exit ramp closed. 
Current Status: Open
Affected Lanes: Exit Ramp
Dates: Wednesday, May 28 - Thursday, May 29
Days Closed: SMTWTFS   20:00 PM - 6:00 AM

This is how it is formated in the td cell. 

<td style='{$td2Style}'><strong>Incident:</strong> {$incident_data_desc}</td>\n";

So as you can see above, there is nothing before it that would cause it to break to a new line both in the table or in the RSS.    So how can I remove that first return only is that is on the same line with it and not below it.    I have tried this and a couple of other things like trim with no luck.   

$description         = $item->description;
    $incident_data_desc  = str_replace("\r", '', $description );

Note, I only need that first one removed, the others are fine. I can do it but it will remove all the breaks and I only want to remove that first one that is causing the line to be on a new line.    Any suggestions?   -Thanks

I have a string of mixed Japanese or Chinese and Western characters and I would really like to leave the western characters and remove the others. Is there any way to detect which UTF-8 characters are Japanese/Chinese and to remove them?

I have tried to use this which I found on another thread but my version of PHP (5.3) will not allow the /u in the following
Code: [Select]
echo "<BR>".preg_replace('/[^\u4E00-\u9FFF]+/', '', $string);
I have tried using various combinations of /p (these, plus others)
Code: [Select]
echo "<BR>".preg_replace('/\p{Bopomofo}+/u', '', $string);
echo "<BR>".preg_replace('/\p{Hiragana}+/u', '', $string);
and the /x{} option tells me the numbers are to large
Code: [Select]
echo "<BR>".preg_replace('/[^\x{4E00}-\x{9FFF}]+/', '', $string);
My string for this example is this but any combination of western and Japanese/Chinese characters are possible in the title.

Alright, so I have a textarea where users can put in text. Everytime they put [ani] and click submit, I want the output to change [ani] into an html code: <img src="mypic.gif">

Is this possible?

Hello,

Im trying to have my search on my site so the URL goes to

index.php?page=search&string=WhatEverWasTyped

How is this possible?

Somewhat new with PHP but I think I'm on the right track. I'm trying to search for a serial number on a sql table. I want a response of the serial # and what column its in. There is 4 columns if that helps (id, 30, 32, 31). (serials 002062008002220 002062008002222 002062008002233 are in the table) When I enter in a serial # 002062008002220 (all serials are 16 digits long). I get a blank page to show up...  my form

<form action="search.php" method="get">
<input id="serials" type="text" name="serials" />
<input type="submit" />
</form>

my php

<?php

$con=mysqli_connect("localhost", "xxx", "xxx", "nsmserials");

if (mysqli_connect_errno ()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$search = mysql_real_escape_string($_REQUEST['serials']);
$query = "SELECT 30, 32, 31 FROM nsmtable WHERE 30 LIKE '%$search%' OR 32 LIKE '%$search%' OR 31 LIKE '%$search%'";

$result = mysql_query($query);

while ($row = mysql_fetch_array($result)){
    echo "<li><span class='name'><b>{$row['serials']}</b></span></li>";
}

mysqli_close($con);

?>

Hello
I am facing a problem which i can not handle. I appreciate for any help.

My Database is:
Code: [Select]
CREATE TABLE IF NOT EXISTS `shops` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `options` text,
  `user_name` varchar(250) NOT NULL ,
  PRIMARY KEY (`id`),
  UNIQUE KEY `user_name` (`user_name`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COMMENT='user data stored' AUTO_INCREMENT=1 ;
And some sample data as below:
Code: [Select]
INSERT INTO `users` (`id`, `options`, `user_name`) VALUES
(1, 'apple-orange-grape-bmw-toyota-fig-', 'user1'),
(4, 'apple-tomato-pc-notebook-yellow-', 'user2'),
(5, 'blue-green-orange-cdrom-', 'user3'),
(6, 'orange-yellow-blue-pink-bread-', 'user4');
How can i display how many apples or green or any item selected by user?
So far i tried in_array, array_count_values but seems no one is working.

Regards

Hey all,
I have a quick question and I know the answer is probably pretty easy but i've been working on it a while now and can't figure out how to get this done.
SOO the situation is. I am looping through an RSS feed and with each entry I want to search for a brand name within the title, and add a company logo beside the entry.  I was playing with something like this but it doesn't work real well..

// Find Kokatat
$find = "Kokatat";
if(strstr($string, $find)) {
$icon = "koksm.jpg";
} else {
$icon = "";
}

I appreciate any input!

Hi, I am trying to search a string for a string of characters in this order ../ and carry out relevant if statements but it returns the same result every time. On echoing my $pos, $pos2, $pos3 and $pos4 variables the first two come back 0 and they are the strings that do contain ../ but the if statements perform the same? I don't understand, any ideas? Thanks...

Code: [Select]
<?php $logo = $info ['logo'];
$pos = strpos($logo, "../");//check if image contains ../
if ($pos == 0) {}
else {
$logo = substr($logo, 3);}

$image1 = $info ['image1'];
$pos1 = strpos($image1, "../");//check if image contains ../
if ($pos1 == 0) {}
else {
$image1 = substr($image1, 3);}

$image2 = $info ['image2'];
$pos2 = strpos($image2, "../");//check if image contains ../
if ($pos2 == 0) {}
else {
$image2 = substr($image2, 3);}

$image3 = $info ['image3'];
$pos3 = strpos($image3, "../"); //check if image contains ../
if ($pos3 == 0) {}
else {
$image3 = substr($image3, 3);}

?>

Hello,

Okay for some reason i cannot do this, when i open a file in php and search for string, it doesn't seem to work, some codes i tried:

Code: [Select]
$filename = 'example.txt';
$searchfor = 'hello';
$fh = fopen($filename, 'r');
$olddata = fread($fh, filesize($filename));
if(strpos($olddata, $searchfor)) {
           //fount it
}
else {
          //can't find it
}
fclose($fh);
(above it just sample text, i was hoping you could give me sample code that will work)

I tried many others like strstr, stristr, preg_replace etc etc, doesn't seem to find it.. this is my text file:

Code: [Select]
sdfsdfsdfsdfsdf[b]hello[/b]sdvsdf
dfadfsdfsdfsddfsdf
sdfsdfsdfs
sdffffffffffffffffffffdv
vsvdsdsf

I don't want to find it by line, i want to simply open the text file and find the string..

thanks..
