I have this string :
$msg = 'A:1509 B:54
1.NS:22
2.TR:56
3.MD:547
4.STS:22
5.SR:15 ';
it would show normal horizontal string. but the variable separated by enter key....
how to convert the enter key to space. thanks
You need to replace any \r or \n characters. You can do that like this:
$msg = str_replace(array("\r", "\n", " "), ' ', $msg);
This replaces anything in the array("\r", "\n", " ") with a space and assigns the new value back to $msg. (The last entry is to address the point from the comments that \r\n would result in two spaces.)
You are trying to get all of the contents onto one line? You could try replacing the new line characters
$msg = str_replace(array("\n", "\r"), ' ', $msg);
This is how to handle it:
$msg = str_replace(chr(0x0D), ' ', $msg);
$msg = str_replace(chr(0x0A), ' ', $msg);

I want to replace the first and last words and sentences .
I use this code.
$text = ' this is the test for string. ';
echo $text = str_replace(" ", "", $text);
when i have use replace code .
all space is deleted and repalsed.
any body can help me?!
i want get this:
this is the test for string.
You probably want the trim function here:
$text = ' this is the test for string. ';
echo '***' . trim($text) . '***';
***this is the test for string.***
Just to round out this answer, if you wanted to accomplish the same thing using a replacement, you could do a regex replace as follows:
$out = preg_replace("/^\s*|\s*$/", "", $text);
echo '***' . $out . '***';
***this is the test for string.***
This approach might a good starting point if you wanted to do a regex replacement with perhaps slightly different logic.
My code simply displays a random line from a text file,
But in my text file most of the proxies look like this: "11.15.19.15:80" I need help how to display only the address on the site, and remove the quotation marks.
<?php
$message_array = file("proxies.txt");
$message = array_rand($message_array);
echo "$message_array[$message]";
?>
All you need to do is wrap the string in a trim():
<?php
$message_array = file("proxies.txt");
$message = array_rand($message_array);
echo trim($message_array[$message], "\""); // 11.15.19.15:80
?>
Note that the second argument in trim() is needed, because your string contains the " characters, rather than uses them to denote the string itself. Adding an escaped backslash ("\"") removes the quotation marks from what is inside the string itself.
I've created a simple demonstration of this at 3v4l.org here.
I think you can use a regex like so:
preg_replace('/["]*/g', '', $message);
Use str_replace. Here is an example:
$message = str_replace('"', '',$message);
You can use the trim function if you just need to remove the double quotes:
$message = trim($message, '"');
Also str_replace:
$message = str_replace('"', '', $message);
I have problem in sending message to my client via socket,the string that I would like to send is like this "##w32,12345678,xxx,5*zy\r\n"
$msg = $_POST['comm_input']; //"##w32,12345678,xxx,5*zy\r\n"
if this is posted i get the value of $msg which is "##w32,12345678,xxx,5*zy\r\n"
but my client will not accept this kind of message..but if I manually do like this without posting the comm_input;
$testmsg = "##w32,12345678,xxx,5*zy\r\n";
It works fine,I tried to look at in firebug there is no double quotes and \r\n.and it works fine.
if I post the comm_input.and look at in the firebug there is double quotes and \r\n,how can I remove this.
You can use str_replace function to remove \r\n.
DEMO
<?php
$testmsg = "##w32,12345678,xxx,5*zy\r\n"; <-- $_POST value
$order = "\r\n";
$replace = "";
$newstr = str_replace($order, $replace, $testmsg);
echo $newstr; //outputs ##w32,12345678,xxx,5*zy
?>
using str_replace, you need to escape the \ with and extra \, hence, \r as string becomes \\r
$msg = $_POST['comm_input']; //"##w32,12345678,xxx,5*zy\r\n" ;
$new_msg = str_replace("\\r\\n", "", $msg);
Edit: to remove double quotes
$new_msg = str_replace('"', "", $new_msg);
Consider reading this article : Escape Sequence in PHP
you can use
$msg = "##w32,12345678,xxx,5*zy\r\n";
$str = rtrim($msg);
Refer trim() and rtrim()
I am working on my Wordpress blog and its required to get the title of a post and split it at the "-". Thing is, its not working, because in the source its &ndash and when I look at the result on the website, its a "long minus" (–). Copying and pasting this long minus into some editor makes it a normal minus (-). I cant split at "-" nor at &ndash, but somehow it must be possible. When I created the article, I just typed "-" (minus), but somewhere it gets converted to – automatically.
Any ideas?
Thanks!
I think I found it. I remember that I have meet the similar problem that when I paste code in my post the quote mark transform to an em-quad one when display to readers.
I found that is in /wp-include/formatting.php line 56 (wordpress ver 3.3.1), it defined some characters need to replace
$static_characters = array_merge( array('---', ' -- ', '--', ' - ', 'xn–', '...', '``', '\'\'', ' (tm)'), $cockney );
$static_replacements = array_merge( array($em_dash, ' ' . $em_dash . ' ', $en_dash, ' ' . $en_dash . ' ', 'xn--', '…', $opening_quote, $closing_quote, ' ™'), $cockneyreplace );
and in line 85 it make an replacement
// This is not a tag, nor is the texturization disabled static strings
$curl = str_replace($static_characters, $static_replacements, $curl);
If you want to split a string at the "-" character, basically you must replace "-" with a space.
Try this:
$string_to_be_stripped = "my-word-test";
$chars = array('-');
$new_string = str_replace($chars, ' ', $string_to_be_stripped);
echo $new_string;
These lines splits the string at the "-". For example, if you have my-word-test, it will echo "my word test". I hope it helps.
For more information about the str_replace function click here.
If you want to do this in a WordPress style, try using filters. I suggest placing these lines in your functions.php file:
add_filter('the_title', function($title) {
$string_to_be_stripped = $title;
$chars = array('-');
$new_string = str_replace($chars, ' ', $string_to_be_stripped);
return $new_string;
})
Now, everytime you use the_title in a loop, the title will be escaped.
I get text via api and sometimes the text can be like so:
hello
world!
How are you?
But I do need the text to be like this:
hello world! How are you?
How to do that?
you can replace the newlines in the text by doing:
$newmsg = str_replace("\n",' ',$yourmsg);
Here is the link to the php function documentation:
http://php.net/manual/en/function.str-replace.php
EDIT: I added a space in the code so it does "hello world..." instead of "helloworld"
Use
$str=" test
hello
world" ;
str_replace ( "\n"," " , $str
) ;
If you want number of replaced count pass the fourth argument
str_replace ( "\n"," " , $str , $count ) ;
$str=<<<EOF
hello
world!
How are you?
EOF;
$s = explode("\n",$str);
print_r(implode(" ",$s));
Here is a really ridiculous solution that I would probably use (bear in mind, ocdcoder's answer works just fine), to make sure I accounted for all possible line endings:
$line_ends = array("\r\n", "\r", "\n"); //notice the order is important.
$new_msg = str_replace($line_ends, " ", $orig_msg);
This way, if there are double line ends, it gets rid of them, but if not, it goes back and checks for single line endings.
But if you want to get more complicated, you could replace your possible carriage-returns with line-ends:
$msg_newline_fix = str_replace("\r", "\n", $orig_message);
$msg_double_newline_fix = str_replace("\n\n", "\n", $msg_newline_fix);
$newmsg = str_replace("\n", " ", $msg_double_newline_fix);
But again, I'm a bit wacky like that. Another crazy solution might be:
$msg_newline_fix = str_replace("\r", "\n", $orig_message);
$msg_array_lines = explode("\n", $msg_newline_fix);
foreach($msg_array_lines as $msg_line){
$clean_line = rtrim($msg_line);
if($clean_line !== '') {
$msg_clean_array[] = $clean_line;
}
}
$new_msg = implode(" ", $msg_clean_array);
But if you know your line endings will be new lines (\n) and not carriage returns (\r) then you are probably safe with a simple one line str_replace.
Finally, you might actually want to preserve line endings when it indicates a new paragraph, something like:
Hello
World!
This is a
new paragraph.
In which case, I would suggest normalizing the line-endings first (making it consistently the same thing so we aren't guessing) and then replacing those empty lines with some kind of safe token you can go back and replace with your new line. Something like:
$msg_carriage_fix = str_replace("\r", "\n\n", $orig_message);
$msg_double_carriage_fix = str_replace("\n\n\n", "\n\n", $msg_newline_fix);
Now we are at the point where we know each line, including empty lines, have only one \n at the end. By replacing the potential \r with two \n, and then replacing only three \n in a row with two \n we avoid the risk of removing any line endings if there were no carriage-return \rs in the first place. Then we can finally do:
$msg_hold_true_linebreaks = str_replace("\n\n", "%line-break%", $msg_double_carriage_fix);
$msg_strip_new_lines = str_replace("\n"," ",$msg_hold_true_linebreaks);
and last but not least:
$new_msg = str_replace("%line-break%","\n",$msg_strip_new_lines);
But,that is only if you really want to keep those true line-breaks and if you want to be extra sure you are ready for carriage-returns, line-ends, and the dreaded \r\n.
I would show yet another version that may shorter and involves using implode and explode, but I'm sure that's enough for now.
edit
Here is a slightly simpler version of that last suggestion, which tries to account for both line endings and intentional line breaks:
$msg_rn_fix = str_replace("\r\n", "\n", $orig_msg);
$msg_r_fix = str_replace("\r", "\n", $msg_rn_fix);
We now know each line ends with a single \n, including empty lines...
$msg_array = explode("\n", $msg_r_fix);
Normal lines each get an array value, but we also know that if the array value is nothing, that it was an intentional hard return...
foreach($msg_array as $msg_line) {
$clean_msg_lines[] = ($msg_line == '') ? "\n" : $msg_line;
}
then we put it all back together:
$new_msg = implode(" ", $clean_msg_lines);
The only flaw is that there will be an extra space before and after each line end. This is easily fixed:
$new_msg = str_replace(" \n ", "\n", $new_msg);
I like this last solution so much, I'm going to copy it below without commentary.
My favorite version
$msg_rn_fix = str_replace("\r\n", "\n", $orig_msg);
$msg_r_fix = str_replace("\r", "\n", $msg_rn_fix);
$msg_array = explode("\n", $msg_r_fix);
foreach($msg_array as $msg_line) {
$clean_msg_lines[] = ($msg_line == '') ? "\n" : $msg_line;
}
$new_msg = implode(" ", $clean_msg_lines);
$new_msg = str_replace(" \n ", "\n", $new_msg);
