I've got the following issue with PHP and PostgreSQL.
In a table I added the following value, mark the spaces.
Things: 10 POLI
When I read this out with PHP it will become
Things 10 POLI
My simpified code (for an ideal world without errors) is:
$query = "SELECT stuff, thing, planets FROM 42 WHERE answer = '-'";
$result = pg_query($connection, $query);
$resultTable = pg_fetch_all($result);
Then with
echo "Things: $result[stuff]";
My question is, which step eliminates all the white spaces? And how to get these spaces back? I know that most people want to remove them, I want to keep them.
that is not a PHP issue, but a HTML issue, becauyse if you output with echo, you do in fact generate HTML code.
The HTML specification defines, that multiple consecutive spaces get rendered as only one space.
If you want to avoid this, wrap a <pre> tag around the string:
echo "<pre>Things: $result[stuff]</pre>";
That's because browser does not recognize more than one space, you can use this code to convert consective spaces to (space understood by browser)
$str = str_replace(' ', ' ', $origText);
Or alternatively wrap your text in <pre> tag if that suites your requirements as suggested in comments below.

I have a string I want to process which looks like this:
HHHHHHHHHHHHHHGGGHHHHHHHHHHHHHHH GGGGGG TTTTT SHHHHHH HHHHHHHHHHHHHHHH
Note how there are multiple spaces between characters. The number of spaces is important, and thus I don't want them to be discarded. When I read this line from a file using php, it prints the following:
HHHHHHHHHHHHHHGGGHHHHHHHHHHHHHHH GGGGGG TTTTT SHHHHHH HHHHHHHHHHHHHHHH
Maintaining only a single space where there were several before. How can I stop PHP from doing this?
Ultimately I want to substring the entire thing into an array of individual characters but I need the array position to be preserved.
Thank you!
EDIT: Example of what I'm talking about:
Replace it with the html entity for a non breaking space to view it rendered in browser's html
<?php
$str = ' HHHHHHHHHHHHHHGGGHHHHHHHHHHHHHHH GGGGGG TTTTT SHHHHHH HHHHHHHHHHHHHHHH';
$str = str_replace(' ',' ',$str);
echo $str;
If you're viewing it with a browser you could use HTML to keep the formatting intact. For instance:
echo '<pre> HHHHHHHHHHHHHHGGGHHHHHHHHHHHHHHH GGGGGG TTTTT SHHHHHH HHHHHHHHHHHHHHHH</pre>';

I think <code> might also work.
Here is the line of code from a PHP file, specifically it is from zstore.php which is a file include as part of the "Zazzle Store Builder" toolset from Zazzle.com
The set of files allows someone like me, who has products for sale on Zazzle and massage that data into a nicer "storefront" which I can set up my way instead of being confined by the CMS structure of Zazzle.com where they understandably want to keep the monkeys (uhmmm... users like myself) from causing too much mayhem.
So... here is the code:
$keywords = str_replace(" ",",",str_replace(",","",$keywords));
Two questions:
Am I understanding what it does and
Is there an extra single or double quote in the string that does not need to be there?
Here is what I think the line of code is saying:
Take the string of characters that the user inputs (dance diva) and assign it to the variable called
$keywords
then run the following function on that character string
= str_replace
(" ","," <<< look for spaces. If you find a space, replace it with a comma
,str_replace(",","" <<< this is the bit I don't understand or which may have a typo
I THINK that it is saying " if you find commas, leave them alone, but I'm not certain.
,$keywords)); <<< then put the edited string of characters backing to the variable called $keywords.
What lead me to look at this was that I was inputting the following:
dance,diva which is what I THOUGHT the script was wanting from me based on the commented text in the README.txt file:
// Search terms. Comma separated keywords you can use to select products for your store
So..
Am I understanding what this line of code is supposed to do?
which, assuming I am correct, and I'm pretty sure that the first half is supposed to work as I've described, now brings me to my second question:
Why isn't the second bit working? Is there a typo?
To review:
dance diva produces results
dance,diva does not
Both, SHOULD work.
Thanks in advance for your help. I have a lot of HTML experience and computer experience but PHP is new to me.
$keywords = str_replace(" ",",",str_replace(",","",$keywords));
You can split into
$temp = str_replace(",","",$keywords);
$keywords = str_replace(" ",",",$temp);
First it replaces all comas with empty string, it is removes all comas. Then replaces all spaces with comas.
For "dance diva" there are no comas so first does nothing, then it replaces space and result is "dance,diva"
For "dance,diva" it removes coma, you get "dancediva" and there in no space to replace next so it is Your result.
Let's say I have a variable $foo:
$foo = " a a blablabla a a";
But when I do var_dump($foo) the following gets outputted:
string(57) " a a blablabla a a"
It's like the length (57 in this case) it's correct and it counts the spaces, but it doesn't display them.
How can I display the full string, including the multiple spaces in between the other characters?
If you use <pre> tag the text appears in the brower as you typed it. Couple of links:

You could also replace spaces with non breaking space .
Web browsers ignore a lot white space in the code which is nice. Otherwise we wouldn't be able to intend our source code or use newlines much...
Are you by any chance doing this in a browser. If so you need to do this.
<pre>
<?php echo var_dump($foo); ?>
</pre>
Because I just tried in command line and I get the output with spaces. Browsers don't handle multiple spaces and they trim them down. If you want a browser to handle multiple spaces you have to use the output inside a <pre> tag or use instead of spaces.
something like echo str_replace(' ', ' ',$test);
I'm pulling articles from specific URLs for conversion to sentences, but the text body has a random behavior of eliminating whitespace between some sentences resulting in:
Jane went to the store.She bought a dog. The dog was very friendly.It had no teeth.
Some of my text is stock symbols (AZ.GAN) etc. So I can't simply insert a space between all periods which have no adjacent whitespace.
Jane bought several shares of (TY.JPN). She lost all her cash money."Arg!" She cried.
The above example would destroy the stock symbol variable.
Curious if anyone knows the cause of this. I have tried several HTML and DOM. I use Simple_DOM to grab the plaintext. Although, I get the same result if I do it manually, or with any other parsing engine.
Unfortunately I don't have an approach for your specific question, but is it possible that the missing space between sentences is actually a linebreak (e.g. \n) that your text viewer (whatever it is) isn't showing you?
Perhaps try something like this just to make sure
var articleContent = ... // get content
articleContent = articleContent.replace(/\n/g, ' NEW LINE ');
Try doing:
$str = trim(preg_replace('~([(].+?[.])\s(.+?[)])~', '$1$2', str_replace('.', '. ', $str)));
I've got some data that needs to be cleaned up into a fixed length format. I'm using PHP to grab the data out, covert it, and put it back in, but it's not working as planned. There is a certain point in each piece in the middle of the data where there should be spaces to increase the length to the proper amount of characters. The code I'm using to do this is:
while ($row = mysql_fetch_array($databasetable)) {
$key = $row['KEY'];
$strlength = strlen($key);
while ($strlength < 33) {
$array = explode(' TA',$key);
$key = $array[0] . ' TA' . $array[1];
$strlength++;
}
}
It's taking a ' TA' and adding two spaces before it, rinse and repeat until the total length is 33, however when I output the value, it just returns a single space. Funny part is that even though it is displaying a single space, it returns a strlen of 33 even if it's not displaying 33 characters.
Any help in figuring this out would be greatly appreciated.
HTML will have extra spaces filtered out.
To force extra spaces to be shown, use ' ' rather than ' '.
#TVK- is correct, HTML ignores multiple-space whitespace - it'll turn it into one space.
In addition to his solution, you can use the CSS instruction white-space: pre to preserve spaces.
Remember that, when doing an output to a webbrowser, it'll interpret it as HTML ; and, in HTML, several blank spaces are displayed as one.
A possibility would be to use the var_dump() function, especially if coupled with the Xdebug extension, to get a better idea of your data -- or to display it as text, sending a text-related content-type.
BTW : if you want to make sure a string contains a certain amount of characters, you'll probably want to take a look at str_pad()
Easiest options for you I think are
Wrap your output in <pre> tags
replace each space with
If you're rendering HTML, consecutive spaces will be ignored. If you want to force rendering of these, try using
Generally using multiple non breakable spaces one after another is a bad idea and might not bring a desired result unless you're using a monospaced font. If you want to move some piece of text to a certain position on your page, consider using margins
You can tell the browser that the text is preformatted
this text will be displayed as it is formatted
spaces should all appear.
new lines will also be apparent
Have you looked into str_pad? something like :
str_pad ( 'mystring' , 33 , ' TA' , STR_PAD_LEFT );
I thing you can use str_repeat
echo str_repeat(" ", 15);
