PHP - Removing Commas From A String And Keeping It A String?
I have the following function, which takes a string with commas in it and attempts remove those commas. The way I have it here is that I use explode to take out the commas, which makes an array, and then iterate through that array to put a string back together without the commas.
function tags_to_sort_by( $sortMeta ) { $sortByArray = explode(",", $sortMeta); $sortByCount = count($sortByArray); for ($i = 0; $i < $sortByCount; $i++) { $sortByString += $sortByArray[$i]; } return $sortByString; } What does not work is the following line: $sortByString += $sortByArray[$i]; Somehow that outputs a 0, which I don't understand. It should output something like: arrayItem1 arrayItem2 array3 etc. My question is if there either is an easier way to remove the commas from the original string or what I am doing wrong in this line: $sortByString += $sortByArray[$i]; // I am trying to concatenate each part of the array back into the string. Thanks a lot for help with this! Similar TutorialsHi! So what I'm trying to do is split a multi dimensional array of strings ( each containing 3 strings inside of 1 array ) so I can write the results to a file. So say I had a bunch of strings inside 1 array :
class File {
function WriteFile ( $filename, $content ) {
$list = [
$content
];
$delimiters = File :: checkDelimiter (
$content,
true,
false
);
$fp = fopen (
$filename, 'w'
);
foreach ( $list as $fields ) {
$fields = File :: SplitFileByDelimiter (
$fields,
",",
3
);
file_put_contents (
$filename, $fields
);
}
fclose ( $fp );
}
}
$file-> File :: WriteFile ( $filepath . $filename, "TEST!, TEST!, TEST!, " . "TEST!, TEST!, TEST!, " . "TEST!, TEST!, TEST!" ); Instead of writing : TEST!, TEST!, TEST!, TEST!, TEST!, TEST!, TEST! ,TEST!, TEST!, TEST! to the file in a straight line, it should write it like this : TEST!, TEST!, TEST!, TEST!, TEST!, TEST!, TEST!, TEST!, TEST! Any help is ABSOLUTELY appreciated! Edited May 22 by AquariaXI Hi, I am trying to find a way that will allow me to convert information passed via POST into array so I can run foreach on the array. For example if information in $_POST[ids] is 1000, 1001, 1002, 1003 I would like to get it into an array $array = array("1000", "1001", "1002", "1003") Thanks I have some data in a table and some of it is Artist names stored as "Last, First" I need to be able to have the script search weather or not someone types "last, first" or "first last". Any ideas? Here's my code: <html> <head> <title>search script</title> </head> <body> <form name="form" action="search.php" method="get"> <input type="text" name="q" /> <input type="submit" name="Submit" value="Search" /> </form> <?php // Get the search variable from URL $var = @$_GET['q'] ; $trimmed = trim($var); //trim whitespace from the stored variable // rows to return $limit=100; // check for an empty string and display a message. if ($trimmed == "") { echo "<p>Please enter a search...</p>"; exit; } // check for a search parameter if (!isset($var)) { echo "<p>We dont seem to have a search parameter!</p>"; exit; } //connect to your database ** EDIT REQUIRED HERE ** mysql_connect("localhost","username","password"); //(host, username, password) //specify database mysql_select_db("mydb") or die("Unable to select database"); //select which database we're using // Build SQL Query $query = "select * from songs where Title like \"%$trimmed%\" or Artist like \"%$trimmed%\" order by Title"; // EDIT HERE and specify your table and field names for the SQL query $numresults=mysql_query($query); $numrows=mysql_num_rows($numresults); // If we have no results, offer a google search as an alternative if ($numrows == 0) { echo "<h4>Results</h4>"; echo "<p>Sorry, your search: "" . $trimmed . "" returned zero results</p>"; } // next determine if s has been passed to script, if not use 0 if (empty($s)) { $s=0; } // get results $query .= " limit $s,$limit"; $result = mysql_query($query) or die("Couldn't execute query"); // display what the person searched for echo "<p>You searched for: "" . $var . ""</p>"; // begin to show results set echo "Results"; $count = 1 + $s ; // now you can display the results returned echo "<table border=1>"; while ($row= mysql_fetch_array($result)) { $title = $row["Title"]; $artist = $row["Artist"]; $number = $row["Number"]; echo "<tr><td>$count.)</td><td>$title</td><td>$artist</td><td>$number</td></tr>" ; $count++ ; } echo "</table>"; $currPage = (($s/$limit) + 1); //break before paging echo "<br />"; // next we need to do the links to other results if ($s>=1) { // bypass PREV link if s is 0 $prevs=($s-$limit); print " <a href=\"$PHP_SELF?s=$prevs&q=$var\"><< Prev 10</a>  "; } // calculate number of pages needing links $pages=intval($numrows/$limit); // $pages now contains int of pages needed unless there is a remainder from division if ($numrows%$limit) { // has remainder so add one page $pages++; } // check to see if last page if (!((($s+$limit)/$limit)==$pages) && $pages!=1) { // not last page so give NEXT link $news=$s+$limit; echo " <a href=\"$PHP_SELF?s=$news&q=$var\">Next 20 >></a>"; } $a = $s + ($limit) ; if ($a > $numrows) { $a = $numrows ; } $b = $s + 1 ; echo "<p>Showing results $b to $a of $numrows</p>"; ?> </body> </html> 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 im having trouble removing ' from strings
so say
$name = "D'vion";
$newname = str_replace("'","",$name);
but this just returns the same.
thanks matt
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==""){ $aircraft = mysql_query("IGNORE aircraft"); } ?> Thanks in advanced! Hey guys! I found a flush function and it seems to be working well, but sometimes it will cut off characters. It's very strange. Here's my flush function: function out($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 $i++; } echo '</div>'; } else { _e( 'An error has occurred, which probably means the feed is down. Try again later.' ); } } %3$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 $i++; } Ashley This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=321479.0 Hello, I have this XML file I am parsing and I have hit a small formatting issue that I can't seem to get around.
Here is what the the output of the RSS looks like.
<description><![CDATA[<div style='text-align:left;'>Exit ramp closed. <br/><b>Current Status:</b> Open<br/><b>Affected Lanes:</b> Exit Ramp<br/><b>Dates:</b> Wednesday, May 28 - Thursday, May 29<br/><b>Days Closed:</b> <font color='#808080'>S</font><font color='#808080'>M</font><font color='#808080'>T</font><font color='#FF0000'><b>W</b></font><font color='#FF0000'><b>T</b></font><font color='#808080'>F</font><font color='#808080'>S</font> 20:00 PM - 6:00 AM</div>]]></description>Notice at the first is "Exit ramp closed." There is nothing before it but, for some weird reason when I parse it. It is on a new line like so, notice it should be up there with "Incident" but, it is dropped down below it. Incident: Exit ramp closed. Current Status: Open Affected Lanes: Exit Ramp Dates: Wednesday, May 28 - Thursday, May 29 Days Closed: SMTWTFS 20:00 PM - 6:00 AMThis is how it is formated in the td cell.
<td style='{$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?

I have tried to use this which I found on another thread but my version of PHP (5.3) will not allow the /u in the following Code: [Select] echo "<BR>".preg_replace('/[^\u4E00-\u9FFF]+/', '', $string); I have tried using various combinations of /p (these, plus others) Code: [Select] echo "<BR>".preg_replace('/\p{Bopomofo}+/u', '', $string); echo "<BR>".preg_replace('/\p{Hiragana}+/u', '', $string); and the /x{} option tells me the numbers are to large Code: [Select] echo "<BR>".preg_replace('/[^\x{4E00}-\x{9FFF}]+/', '', $string); My string for this example is this but any combination of western and Japanese/Chinese characters are possible in the title. 2011.12.06 19:00-20:00 / ふくいちライブカメラ (Live Fukushima Nuclear Plant Cam) | Uploaded: 06 Dec 2011 Thanks for any help. Hi, I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks: Code: [Select] <?php session_name("MyLogin"); session_start(); $targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder; $targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('m4a','mp3','flac','ogg'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } } echo $targetFolder; ?> I added Code: [Select] echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select] $targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string. Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago!

My issue is that I can't think of a way to edit a XML file using PHP's XML functionality and then assign the edited contents to a string instead of saving the file. Because my issue is that I have to edit the XML file based upon a string brought from a remote location then give it back to that remote location using a string again, to be exact I am doing it via Linux command line utilizing SSH2.

The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible! at the moment i've got Code: [Select] <?php $url = $_SERVER['REQUEST_URI']; $tag = strstr ($url, 'sobi2Id='); echo $tag; ?> but this returns an unexpected T_STRING, expecting ',' or ';' Can anyone debug this? I may well be being really silly! |
