PHP - Finding And Removing Numbers (1-25) From A String ...

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?

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.

What I want to do is simple:
The string "this_is_an_example.php"

should return "this_is_an_"

while:
"this_is_an_example_filename.php
should return "this_is_an_example_"

Is there a simple function which can cut off the part after the last _ ?
I have been looking and trying several functions, but can't seem to find the right one for this.

(the last _ being cut off of course wouldn't be a problem I couldn't live with :-) )

Any help will be greatly appreciated!

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])
What i need to have is that the script will automatically "find" that Matching Word for me with ANYwhere of the string of $abs (not just the beginning or the ending)". 

not making it confusing, but the obvious word in this I am looking to find is the word, "words".
😕

Thanks so much for any help.

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

Hello Everyone,

I am working on a project I pull the field names from the database. I am trying to remove the underscore (_) when the field name is displayed. Does anyone know how I would do that?

Here is the code that I am working with
Code: [Select]
$i = 0;
    while ($i < mysql_num_fields($fieldnamesquery_result)) {
        $meta = mysql_fetch_field($fieldnamesquery_result, $i);
        if (!$meta) {
            echo "No information available";
        }

        $meta = str_replace("_", " ", $meta);

        $tablecolumn .= "<p>" . $meta->name . ":<input type='text' name='" . $meta->name . "' id='" . $meta->name . "' /></p>";
        $i++;

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!

Working through some beginner stuff and ive copied some code straight out the textbook, word for word yet it produces:

Parse error: syntax error, unexpected T_ECHO, expecting ',' or ';' in C:\wamp\www\PHP Work\StringtoNumbers.php on line 11

         echo "<li>".($n2 + 2)."</li>";

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?

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.

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>

      <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,

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
