Hi - newbie to php - I need to search a string and possibly replace part of it.  This is how I would do it in perl:

Code: [Select]
if ($homepage) {
if ($homepage !~ /http/i) {
$homepage = "http:\/\/" . $homepage;
}
}

I have a homepage field in the database but sometimes people put the http in, and sometimes they leave it out.  In perl I can figure it out and format accordingly but it doesn't work in PHP.  I'm not sure if the first line even works in PHP.  Maybe if to say something like:

if $homepage is not equal to nothing. I'm not sure.

Any help would be appreciated.

Thanks.

I have  string like this (without the spaces)

[ QUOTE="Adrock"]This is a test message[/QUOTE ]

How do i get just what is between the double quotes taking into account in the message there could be double quotes?

I've tried this but it doesn't echo anything unless i put the square brackets in but i want the username

$origauth = html_entity_decode($message);

$b = substr($origauth, strpos($origauth, '&#034') + 1); 

$c = substr($b, 0, strpos($b, '&#034')); 

echo $c;

Let's say I have a variable called $big_paragraph

I want to display the variable IF it contains the word "hello".  The word may or may not be there AND it could be anywhere in that paragraph (separated by a space before and after it to signify that it is a word).  So I can't use substr since it assumes I know the position.

Thanks.

hi php freaks,

any help would be great

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!

Hey there.
Thinking this should be an easy one but I can only seem to find info on the string replace function.
What I'm trying to do is strip everything after the @ from an email variable.

So for example $mail variable comes in as
me@gmail.com

How would I strip the variable to only contain me and remove the @gmail.com

I'll keep searching for the answer myself but if anyone can throw me a bone it's be appreciated.

Cheers

Hey guys I'm having an issue trying to get my PHP to display the first url of my exploded string and non of the others. The SQL table column contains strings like this:

http://www.imgurl.com/image.jpg,http://www.imgurl.com/image2.jpg,http://www.imgurl.com/image3.jpg,http://www.imgurl.com/image4.jpg

I have the following DOM document ( this is a sample document and is "as is", it's 100% intended to look like this ):

<everything>
 <cars>
     <car>ladia</car>
     <car>ferrari</car>
     <garage>big blue building</garage>
      i also have a McLaren F1 but i wont brag about it
 </cars>
 <houses>
   <house>Big Red House</house>
 </houses>
</everything>

This is all being put into a
$newdoc = new DOMDocument();

$myString = ................. ; // ????? I only want the content of <cars> in here, and without having the <cars> tag


How can I make this "$myString look like the following:

$myString = '
     <car>ladia</car>
     <car>ferrari</car>
     <garage>big blue building</garage>
      i also have a McLaren F1 but i wont brag about it
';



Preferably without any looping.

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.' );
    }
}

%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++;
}

Hello,

I have several job categories on a recruitment website:

$job_category[0]="accountant";
$job_category[1]="php programming";
$job_category[2]="baseball";

these job categories are contained within the urls imediately after the recruiting company's name and before the word "jobs", so we could have the following urls:

www.url.com/company_name_accountant_jobs
www.url.com/another_company_name_baseball_jobs
www.url.com/yet_another_company_name_php programming_jobs

Using the array $job_categories and the page path after the foward slash (e.g. yet_another_company_name_php programming_jobs) please could you tell me how to strip out the job category and the company name? (I'll extract the page path using a mod_rewrite)

Thanks

Hi all, first time here as I am a bit stuck. I am by no means a programmer and I was hoping that someone out there may have a simple solution to my problem?... So here goes"

I have a voucher/offers site up-and-running. The site content is generated from an external feed. I want to create other sites and I want to track what sales/clicks have come from where.

An example of the feed: (http://www.awin1.com/awclick.php?mid=251&id=28971&clickref=[URL_REFERENCE]&p=http://www.247electrical.co.uk)

As you will see, I have [URL_REFERENCE] in each link. I want to automatically change that part of the string in the database. Does anyone have any thoughts?
