PHP - How Can I Concat Two String Removing Newline Characters From Mddle Of The 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 all,

I'm using the form 'method="get" action="results.php"' on my search form...
Say someone uses my 'Photo search' to search my database for aircraft, and leaves all fields blank. In this case, the only field of the search is 'aircraft'.


This will take the user to 'results.php?aircraft='.

Is there anyway to remove the sting if there is no search value? So it would just read 'results.php'?

This is the code i have so far:


Code: [Select]
<?php

if(isset($_GET['aircraft'])){
$aircraft = $_GET['aircraft'];
}

if($aircraft==""){
$aircraft = mysql_query("IGNORE aircraft");
}

?>
Thanks in advanced!

Hello guys,

I want to remove part of a string and convert it to a var instead of echoing it out.. How would I do it..

$string = "temp_photo/testing.jpg";

I want to remove temp_photo

so the out put should be
$filename2 = testing.jpg

Please advise..

Thanks, Dan

Does anybody know of a function or a way of letting me get the string between whatever characters? Say I had [SOMEWORD] text [SOMEWORD] then how could I go about getting the value "text", please note I'm not trying to make bbcode or similar.

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++;
}

How I can explode by a series of characters (not one single character)? For example, divide the string to an array by any of these characters "," and ";" and "."

$string = "this, that;some.word;second";

I want to put all of these words into an array.

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);}

?>

Am looking forward to removing all the numeric characters upto and including the leading "/" in

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

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>

   <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,

Hi

I am trying to replace characters in a string with images so character 'a' will be replaced with a.jpg etc  I have tried the following code but that doesn't result in the desired effect as the updated string gets it's characters replaced as the script works through it so the 'img' in the first updated string gets replaced with with images and it all ends up quite a mess.  Is there a simpler way to do this?

$content = "abc" ;
$content = str_replace("a", "<img src=images/a.jpg >", $content);
$content = str_replace("b", "<img src=images/b.jpg >", $content);
$content = str_replace("c", "<img src=images/c.jpg >", $content);
$content = str_replace("d", "<img src=images/d.jpg >", $content);
$content = str_replace("e", "<img src=images/e.jpg >", $content);
$content = str_replace("f", "<img src=images/f.jpg >", $content);
$content = str_replace("g", "<img src=images/g.jpg >", $content);
$content = str_replace("h", "<img src=images/h.jpg >", $content);
$content = str_replace("i", "<img src=images/i.jpg >", $content);
$content = str_replace("j", "<img src=images/j.jpg >", $content);
$content = str_replace("k", "<img src=images/k.jpg >", $content);
$content = str_replace("l", "<img src=images/l.jpg >", $content);
$content = str_replace("m", "<img src=images/m.jpg >", $content);
$content = str_replace("n", "<img src=images/n.jpg >", $content);
$content = str_replace("o", "<img src=images/o.jpg >", $content);
$content = str_replace("p", "<img src=images/p.jpg >", $content);
$content = str_replace("q", "<img src=images/q.jpg >", $content);
$content = str_replace("r", "<img src=images/r.jpg >", $content);
$content = str_replace("s", "<img src=images/s.jpg >", $content);
$content = str_replace("t", "<img src=images/t.jpg >", $content);
$content = str_replace("u", "<img src=images/u.jpg >", $content);
$content = str_replace("v", "<img src=images/v.jpg >", $content);
$content = str_replace("w", "<img src=images/w.jpg >", $content);
$content = str_replace("x", "<img src=images/x.jpg >", $content);
$content = str_replace("y", "<img src=images/y.jpg >", $content);
$content = str_replace("z", "<img src=images/z.jpg >", $content);


echo $content ;

Any help would be gratefully appreciated.

Thanks

I want to allow Alphabetical strings, Numeric strings, and Alphanumeric strings. For example "Bob", "1234", "bob1234" are all valid.

I want to check if the string has invalid characters, return true if it does (or false, which ever method works).

How can I do it?
