PHP - Remove All Alpha Characters From A String
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 Similar TutorialsAm looking forward to removing all the numeric characters upto and including the leading "/" in 90/_featuredarticles/2011/12 Regards 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 I have a form with some dropdownlist that get populated dynamically(depends on what the user chooses) with jquery and an xml file. In the form I have a button that takes the info and populates another form with the values of the ddl. I have coded script which populates the second form with jquery and the name of each input get dynamically added like so: Code: [Select] <input type="text" value="'+model+'" name="Model_'+model+'" id="'+model+'" readonly size="'+model.length+'" /> <input type="text" value="'+model+'" name="Model'+model+'" id="'+model+'" readonly size="'+model.length+'" />> <input type="text" value="'+color+'" name="Color'+color+'" id="'+color+'" readonly size="'+color.length+'" /> <input type="text" value="'+part+'" name="Part'+part+'" id="'+part+'" readonly size="'+part.length+'" /> <input type="text" value="$'+price+'" name="Price'+price+'" id="'+price+'" readonly size="'+price.length+'" /> <input type="text" value="'+qty+'" name="Quantity'+qty+'" id="'+qty+'" readonly size="'+qty.length+'" /> <input type="text" value="'+total+'" name="Total'+total+'" id="'+total+'" readonly size="'+total.length+'" /> What I want to do is grab the name of the element and remove the underscore and everything else form rileft to right so I am left with just the word before the underscore. I tried using substr($key,0,-28) but that wont work since everything after the underscore will have a different length. I was wondering if there is a way i can keep everything before the underscore and remove the underscore and everything after that. Thanks in advance for any input I get. In my .htaccess, I have the following to enter a domain name then a store number such as www.domain.com/c111
The page storeNumber.php displays perfectly call the correct variables through the _GET.
The help I got and has been set up works for an Alpha and thre rest numbers.
What would be rewriterule be to use any random string of Alpha Numberic characters? Such as C123, 12CF, cf15, C2f5...

Thanks for any help in advance,

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);} ?> How I can explode by a series of characters (not one single character)?

"' /></p>"; $i++; This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=320682.0 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. 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.' ); } } 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? 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 Megalos (paul) Please can someone advise how I remove the | characters from a string? I tried the following but get errors that... Warning: preg_replace() [function.preg-replace]: No ending delimiter '|' Code: [Select] $value = preg_replace("|", "", $value); 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:
It is supposed to look like this: 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 a variable called $content and I want it to stop execution at 25 characters... How can this be accomplished? Thanks in advance. |
