PHP - Explode An String By Some Characters

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.

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

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 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++;

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.

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?

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.' );
    }
}

Hi,

Im looking at using a statement like this to remove all text characters from a string.

  $outgoing = substr_replace($incoming,"",-1); 

The string is a currency that has a currency symbol in the beginning of the string, like "R500.00"

I would like to remove the R, so it is just a numeric value...

Please can you help me with any ideas on how to get this going? Been reading so much and its all confused me too badly.

Regards,
Chris

I have a large amount of text, (text can be different at any time), I count the number of characters in the string,and divide it by 2 so that half of the text will be in one variable, the other half in the other, however I am not sure how to get the split function, or whichever function to split it by the number of characters.

example:


$text = "lorem ispum dolar sit amet, consecterur adiscing elit. Donec dictum placerat sapien, in eliefend liber";
$cut = strlen($text)/2;
//(here's where i cannot get it to work/do not know which function to use and how to use it)
//but what I want it to do is to split it half way.

I have a variable called $content and I want it to stop execution at 25 characters... How can this be accomplished? Thanks in advance.

Hi.. I am relatively new. 

I am trying to show an image link in my code below:

$image = "<img src=<imgpg/" . $part_no . ".JPG />";

<td  class = "guide_body" width = "66%"></td><td align = "center"><?php echo $image;?>

There is more code but these are the problem lines I believe.  Both are within the php environment.

This is producing:
http://localhost/%3Cimgpg/AF00016B.JPG

It is supposed to look like this:
http://localhost/imgpg/AF00016B.JPG

So it is adding %3C for some reason between localhost and imgpg directory.  I have no idea why this is happening.

Is there something I can do to prevent this from happening?  Or is there something I can do to erase the extra characters.  (I'm not sure if they might be different though at some point.  I have the same problem both on my local computer and the remote server.)

Thanks very much for any help!!

I have sen this function before but can not remember what it is or how to code it. It allows you remove only defined characters from the end of the string. I am not looking to replace any occurrence anywhere in the phrase, just the end.

For example lets say I want to remove"ld!" from phrase "Hello World!" That function would return "Hello Wor"

Thanks

How could I split a string in half but not in the middle of a word?


$information = "This is the string of text, however at some point in the sentence a word may get split in half.";
$cut = round(strlen($information)/2); ///where to cut (50%)
$split1 = substr($information, 0, $cut); //first half
$split2 = substr($information, $cut); // second half

Hi Guys

I'm returning to programming after 5 years, almost a newbie.

I have a field(column) in a MySQL database table that has strings of characters separated by a delimiter (||).

For example: (TOM||PAUL||HARRIS)

I would like to separate the strings into an array.

Something like this:
ARRAY[0] = 'TOM';
ARRAY[1]='PAUL';
ARRAY[3]='HARRIS';

Can some one tell me how to do this?

TIA.
