The solution is broken because of:
1) you have missed spaces after comma in two places. It should be like this:
$cc = trim($cc,, ); // - here space after comma in the second argument
$result = preg_replace('/(\s?)(,)(\s?)/i', ', ', $cc); // -- the same, here 
space after comma in replacement string.

2) it doesn't work with address lines like this:

To: Some   strange ,, person name strper...@example.com

[Shiplu Mokaddim]

 If you are looking for a one liner reg ex, it may take some time. This may 
lead wasting your development time. Better you do the following,

1. replace the string with tokens in address.
2. Split using comma.
3. Apply common email regex.
4. Replace tokens with actual strings.
5. Rebuild/join the string with , 

With this approach you can validate individual emails too.

I just mocked this up now, and only tested it twice.  It's not the
most elegant solution, and probably shouldn't be used in high-demand

?php

$str = '%ECARBME%TIPLUP%%%E%%';
$chars = 'abcdefghijklmnopqrstuvwxyz';

echo multi_replace($str,'%',$chars).PHP_EOL; // Case-sensitive,
random, straight replace
echo multi_replace($str,'%',$chars,0,1,1).PHP_EOL; //
Case-insensitive, random, randomg casing

function 
multi_replace($str,$targ,$chars,$sens=true,$random=true,$caserand=false)
{

// Loop through while $targ is still found in $str
while (strstr($str,$targ) !== false) {

// If we're randomizing, pick the character; else the
first (or only)
if ($random == true  !is_null($random)) {
$replace = $chars[mt_rand(0,(strlen($chars) - 1))];
} else {
$replace = substr($chars,0,1);
}

// If we want random casing, do that; else make no change
if ($caserand == true  !is_null($caserand)) {
if (mt_rand(0,1) === 0) {
$replace = strtolower($replace);
} else {
$replace = strtoupper($replace);
}
}

// If we don't want case sensitivity, set the regexp modifier
$mod = $sens == false || is_null($sens) ? 'i' : '';

// Perform the match and replace only one character now
$str = preg_replace('/'.$targ.'/U'.$mod,$replace,$str,1);

} // End of loop

// Return the modified string
return $str;
}

Quick guess trying to be fairly performant:

function fill_puzzle($puzzle, $puzzle_filler) {
$puzzle_length = strlen($puzzle);
$puzzle_filler_length = strlen($puzzle_filler);
 for ($i = 0; $i  $puzzle_length; $i++) {
if ($puzzle[$i] == '%') {
$puzzle[$i] = $puzzle_filler[mt_rand(0, ($puzzle_filler_length - 1))];
}
}
 return $puzzle;
}

echo fill_puzzle($puzzle = %ECARBME%TIPLUP%%%E%%, $puzzle_filler =
ABCDEFGHIJKLMNOPQRSTUVWXYZ);

Happy Easter :)

well david actually $var = str_replace(chr(13),\n,$value) will replace

u need to put

$var = str_replace(chr(13),br/,$value) in order to got the required

Hello;
I have the following  code:

$prps = str_replace(\n, ' ', $input[3]);


Are you sure $input[3] doesn't have two newlines at the end?

Why not use trim() to be sure?


  $request = str_replace(// var purpose = {} ;\n, var purpose =
'$prps';\n, $request);

In the first line $input[3] is a string formatted with new lines at the
end of each line.
It is to be used to initialize a javascript variable (in the second
line above), in an html file
template.
When the html file is generated from the template, the javascript
written to it fails
with unterminated string literal error message.
When opening a view source window, the 'var purpose...' line does have
the string
broken up with extra spaces at the beginning of each line. This
indicates that
the new line was not replaced with the space. The space was merely
added after
the new line.
How do you replace a new line with php in a case like this?


Why do you want to replace it, you just said you wanted to remove it above?


Testing this is very tedious.


Do you use Firebug?  It's a Firefox extension.  Makes debugging
Javascript very easy.

Also you might try the 'view rendered source' extension.  Lets you
view the live DOM, not just the possibly outdated version of your html
the view source option gives.


Each time I have to go through and undo
file modifications that this function performs in addition to the above.
So it is not just a case of making a change and reloading the file
and rerunning it.

$out = str_replace(\n, '\n', $in);

This will actually have a \n show in the javascript, so when it is

Right?


I think that was my mistake- not differentiating between the two.
Symbols and such I wanted to replace as substrings, yet noise words I
wanted to replace as words. Now that I've created two arrays, one with
symbols and one with noise words, things are on track.


Try something like this:

$string = The quick sly fox jumped over a fence and ran away;
$words = array('the', 'a', 'and');

function make_regex($str) {
  return '/\b' . $str . '\b/i';
}

$search = array_map('make_regex', $words);
$string = preg_replace($search, '', $string);
print $string . \n;


I was completely unaware of the array_map function. Thank you- that is
exactly what I needed.


What you really need to do that is to match word boundaries, NOT string
boundaries.  So you take your list of words and mutate *each one* (that's
what the array_map() is about) into a regex pattern that finds that word,
case-insensitively.  Then you use preg_replace() to replace all matches of
any of those patterns with an empty string.


Yep.


You were close.  What you were missing was the array_map(), because you needed
to concatenate stuff to each element of the array rather than trying to
concatenate a string to an array, which as others have said will absolutely
not work.


Yep.


I can't guarantee that the above code is the best performant method, but it
works. :-)


It certainly does. Of course I'm not using it exactly how you pasted
it, but you got me on track. Thank you very much.

it's string replacement not regexp replacement, therefore the '^' and '$' are

the first argument to the str_replace() call is the string literal:

'^Array$'

... you can't concatenate strings and arrays like that (and get the result you

instead, your function call should look like this:

$searchQuery = str_replace($noiseArray, ' ', $searchQuery);

I need to remove the noise words from a search string.

Yes, that's a literal Array in the string. You cannot, and you should
remember this, you cannot concatenate strings and arrays. What would you
expect it to do?

Now, the answer is this...

$searchQuery = str_replace($noiseArray, ' ', $searchQuery);

However, what you seem to be doing is putting regex syntax where it
would have no effect even if $noiseArray was not an array. If your
intention is to replace the words rather than just the strings then you
need to look at preg_replace (http://php.net/preg_replace) and you'll
need to decorate the strings in $noiseArray with the appropriate
characters to make them the search pattern you need - full details on
the preg_replace manual page.

You sure?  This is what they said originally:

Nothing else is relevant, but $searchQuery will get passed to the

Try something like this:

I need to remove the noise words from a search string.


Yes, that is also part of the aim.


How come?  Not trying to be facetious here.  I'm just wondering if  
you see a benefit that I don't.  For example, say the hacker injects  
some sql and you use mysql_real_escape_string.  You end up with  
something like this... actually, I'll do one step further and just  
use the quote_smart function described in the  
mysql_real_escape_string page of the php manual:


$query = sprintf(SELECT * FROM users WHERE user=%s AND password=%s,
quote_smart($_POST['username']),
quote_smart($_POST['password']) );

Say the user tried to inject sql in $_POST['username'] and it looked  
something like:   root';drop all;


Having used quote_smart, the value of $query ends up

SELECT * FROM users WHERE user='root\'\;drop all\;' AND  
password='something'


The sql injection fails.  The data is seen as a literal.  The  
database is going to think there's no user with that name.  That  
means that even if the user did include extra words, they're just  
part of the value that is checked against user names - rather than  
being see as potential commands.


I'm not sure if I'm describing this well, so let me know what you  
think and I'll go from there.

Can you explain what you are trying to do with the ^ and $?  What is a

The purpose of the ^ and the $ is to define the beginning and the end of a word:

No, actually, ^ and $ define the beginnning  end of the entire 
expression being searched, not the boundaries of a single 
word.  Therefore searching for ^mouse$ will locate mouse only if 
it's the only word in the entire string, which I gather is not what you want.


I suspect what you want is either this:

(^| )WORD( |$)

(the word bounded by either the start/end of string or a space)

or perhaps better yet this:

\bWORD\b

(the word bounded by word boundaries).

See [PCRE regex] Pattern Syntax
http://il2.php.net/manual/en/reference.pcre.pattern.syntax.php



Further to your problem, I believe this is incorrect:

$noiseArray = array(1, ...
...
$searchQuery=str_replace( ^.$noiseArray.$,  , $searchQuery);

Since $noiseArray is your entire array, it doesn't make sense to 
enclose it in word boundaries of any kind.  Instead, I imagine each 
member of the array needs to be bounded individually.


If you go this route, perhaps you could enclose each member of your 
original array in \b word boundary sequences using an array_walk 
routine so that you don't have to muddy your original array 
declaration statement.

Re: [PHP] str_replace on words with an array

[Myron Turner]

I never use this function, since I always use regular expressions, but
according to the manual:
 If you don't need fancy replacing rules (like regular
 expressions), you should always use this function instead of
 ereg_replace() or preg_replace().

So, I assume your problem initially was that you were using regular
expression syntax and this function doesn't accept regular expressions.

Is your aim to get rid strings of all the items in the $noiseArray? Your
 $noiseArray includes the entire alpahabet, so it's no wonder that you
end up with empty strings!

IIRC str_replace() does not interpret or understand regular expression

Ok, this is what the compiler will see...

$searchQuery=str_replace(^Array$,  , $searchQuery);

Yes, that's a literal Array in the string. You cannot, and you should
remember this, you cannot concatenate strings and arrays. What would you
expect it to do?

Now, the answer is this...

$searchQuery = str_replace($noiseArray, ' ', $searchQuery);

However, what you seem to be doing is putting regex syntax where it
would have no effect even if $noiseArray was not an array. If your
intention is to replace the words rather than just the strings then you
need to look at preg_replace (http://php.net/preg_replace) and you'll
need to decorate the strings in $noiseArray with the appropriate
characters to make them the search pattern you need - full details on
the preg_replace manual page.

Hope that made sense.

will, with, would, you, your);

Do any of the characters in there need escaping (other than the $
which is already escaped)?

How does on go about looping through the array, matching only whole
words? This didn't quite do it:
$searchQuery=str_replace( ^.$noiseArray.$,  , $searchQuery);

And neither did this:
$searchQuery=str_replace( /^.$noiseArray.$/,  , $searchQuery);

You're absolutely right -- I was focusing so much on the regexp 
syntax that I failed to broaden my gaze...


When the OP corrects his PHP to use preg_replace() instead of 
str_replace(), I believe he'll still need to provide word boundaries 
around each member of his noise-word array, otherwise the function 
will simply remove all letters and digits from the words in the 
search-string he considers meaningful and he'll end up searching thin air.


Aside, without knowing the context of his search, it seems a bit 
extreme to remove all single characters from the search string.  It's 
not hard to think of examples of them occurring as part of valid 
entity names in our universe -- she got an A, Plan B From Outer 
Space, Vitamin C, etc.


An alternative strategy might be to trust the user to enter a valid 
search string and simply warn them that the quality of the answer 
they get will depend on the quality of their input.

Paul

Thanks all for the heads up with the str_replace not working with
regexes. Duh! I've switched to preg_replace, but still no luck. (nor
skill, on my part)

I'm trying to use array_walk to go through the array and deliminate
each item with /b so that the preg_replace function will know to only
operate on whole words, but I just can't seem to get it. I am of
course Ring TFM and Sing THW but with no luck. A push (link to TFA or

IMHO, unless you're going to be doing a lot with each element of the
array it's easier to do it without using array_walk.

foreach ($arr as $key = $val)
$arr[$key] = \\b.$val.\\b;

Wrok (ISBN 1-86100-835-X) in 2003.


I've looked for the download support files they claim to have, but found 
none.


http://support.apress.com/books.asp?bID=186100835xs=0Go=Select+Book

I've contacted one of the authors, let's see if he provides the code. If 
he does, I'll send it to you.


hth's.

PHP list,

This may be a simple matter. Please feel free to tell me to RTFM if 
you can direct me to exactly where in the FM to R. Or, alternately, 
please use simple explanations, as I'm not an experienced PHP coder.


I'm building a simple content management system, where users can 
enter text into a web form. The text is stored in a MySQL database. 
The text should be plain text.


When the text is retrieved from the database for display, I want to 
add some HTML tags so I can control the format with an external CSS.


I'm assuming the best way to do this is with str_replace(). But 
there are some complications which make me unsure of its usage.


Dave:

RTFM -- yeah, unfortunately, there's a lot of that going around -- 
most justified, some not.


In any event, I think this is where you're going wrong -- don't use 
str_replace() to alter the *content* at all !


If you know css, then keep the content separate from presentation. 
Content comes from your mysql and you should be able to place it 
within html markup where its presentation is controlled by css.


For example, if I have a text paragraph ($my_paragraph) that's been 
pulled from mysql and I want to show that paragraph in html, then I 
would do something like this:


div=content
p
?php echo($my_paragraph); ?
/p
/div

That way I use use css to control how that paragraph will look with 
those div and p tags and, at the same time, make the content easy 
to handle.


If you want to allow users to enter html tags themselves, then you're 
asking for a bit of trouble IMO because you are relying upon them to 
do the mark-up correctly.


For example, if someone entered h1This is what I want to say/h1 
-- how would you handle it? Also note that if that was entered 
as-is your page would not longer be well formed and would probably 
cause problems with the rest of your page, not to mention not 
validating.


If you think you can write code to fix their mistakes, then I think 
that's a mistake for users can screw up code even more than 
programmers can. :-)


Additionally, if you don't handle the input right, then there's a 
security concern, such as mysql injection.


If you want to give your users the option of having headlines and 
body of work, then provide a Headline box and Body of Work box and 
then manage those entries in your markup.


I think you get the idea.

I'm sure there are other ways to do this, but this is the way I've done it.

Re: [PHP] str_replace(), and correctly positioned HTML tags

[Dave M G]

Tedd, Adam,

Thank you for your advice. While I'm very grateful for your advice, 
unfortunately, it seems that the core of what you suggest do not fit my 
situation.


First, with Adam's suggestion that I use br / instead of p. The 
output I am generating is akin to what csszengarden.com generates, so 
that I can have complete CSS control over page layout and style. br / 
tags are limited in their scope of design control as compared to p 
tags, so they are insufficient.


Second, with Tedd's advice that I place the variable without formatting 
within the HTML code. I apologize if I was unclear, as I seem to have 
given you the wrong impression. I am absolutely trying to separate 
content from design, which is why everything the user stores is in plain 
text, and all the formatting happens when it is displayed. None of the 
modifications which add HTML to the variable get put back into the database.


The only small formatting consideration that does get stored in the 
database are the simulated tags (eg: --++ for h3). I'm not totally 
thrilled about letting users create some formatting with simulated tags, 
but the trade off is for giving the users more flexibility. I'm 
following the same model as WikiMedia, SMF Forums, and other PHP based 
user input interfaces. And I am trying to be more strict and less 
expansive than they are.


I really am grateful for your advice, but it seems that I really do need 
to find a way to create p tags around the text when it is displayed.


But I definitely thank you for giving me something to think about, and 
also the tips on how to make my code more efficient.


It's my hope that someone can still steer me towards the ability to get 
p tags surrounding paragraphs, and to be able to separate h3 and 
other tags from within those p tags.

Instead of using br / I would use p/p tags.  That's just me though. :)

 the return is converted to br /\r (leaving the return). AND then when
 converted back for for the textarea both are stripped out, that is, there
 is nothing in front of the first character. When resubmitted for UPDATE:
 
  mysql SELECT jbs_jobDesA FROM jobs WHERE jbs_ID=77 \G

 jbs_jobDesA: Lesequam coreet la feum nulla feu facil iriure faccummolut

 Q. Why is that first return treated differently? All other returns are
 treated as expected.

You really shouldnt convert the data to br's into the database,
just do it at the time at displaying it in html, and keep the raw
data in the database.

// add to database (prepare avoiding sql injection)
$field = mysql_real_escape_string($_POST['textarea']);
$sql = update jobs  set jbs_jobDesA = '$field'  WHERE jbs_ID=77;

// output to html, removing xxs ablity and add html br's
$field_from_db = $row['jbs_jobDesA'];
echo div . nl2br(htmlentities($field_from_db)) . /div;

// output to a textarea, removing xxs ability
$field_from_db = $row['jbs_jobDesA'];
echo textarea . htmlentities($field_from_db) . /textarea;

This would work much nicer. No need to do any two-way convertion of
your data.

I'm not completely sure, but I think they're talking shite. If curl is

You could try replacing every letter in the word curl with it's #xxx;

 Why ?

You should know that, unless you tell php to limit the number of replaces, it 
will keep on replacing until it doesn't find a match anymore. 

Here is what happens:

 ?php
 $texte = 'cd' ;
 $original = array('a', 'b', 'c', 'd', 'e', 'f', 'g');
 $modif = array ('c', 'd', 'e', 'f', 'g', 'h', 'i');
 $texte = str_replace($original, $modif, $texte) ;
#after first replacement
$texte='ef'
#after 2nd replacement
$texte='gh'
#after third replacement
$texte='ih';

If you want to prevent this, tell the function that you only want 2 
replacements.  Like this:
$limite=2;
$texte=str_replace($original,$modif,$texte,$limite);

Hope this helps

With kind regards

Hi Duncan,
that in fact was the key and only way to get a proper result.
I found this script on the preg_replace page of php.net:
// Function highlights $words in $str
function highlight_words($str, $words) {
  if(is_array($words)) {
   foreach($words as $k = $word) {
 $pattern[$k] = /\b($word)\b/is;
 $replace[$k] = 'b\\1/b';
   }
  }
  else {
   $pattern = /\b($words)\b/is;
   $replace = 'b\\1/b';
  }
  return preg_replace($pattern,$replace,$str);
}
Which works excellent!

You should look into using a regular expression as these can recognise word
boundaries when matching (preg_match, preg_replace, etc).

I think this solution will apply to your other post as well.

I think that's a bad example you read. It doesn't describe how to  
search on a word it describes how to search on a string, which is  
what you ended up doing.
For things like this I use arrays. Assuming your words are separated  
by spaces, you can get an array of all the words by doing:
$word_list = explode(' ', $text);

Then you can cycle through each element of the array (there are a  
number of ways to do this), testing if it equals your word and replace  
it if it does.
Then put it all back together with:
$text = implode(' ', $word_list);

Re: [PHP] str_replace on words?

[tg-php]

As mentioned in the making words bold thread, works aren't always separated 
by spaces.  Sometimes they end a sentence so are followed by a period or other 
punctuation.  Sometimes you have strings like and/or where they're separated 
by the forward slash, etc.

You really have to do some kind of regex expression to get this right when 
substituting whole words and not just any substring.

A thought in the exact right direction, just need to follow through with the 
rest of the thought.

 http://www.totallyphp.co.uk/code/ 
 find_and_replace_words_in_a_text_string_using_str_replace.htm

 Unfortunatelly it does not work the way I want, because if I want to  
 replace the word in all passages containing the characters in are  
 replaced. For example Singapore.

 Does anybody know how to do this on just words?

 Thank you for any hint,

 Merlin

Re: [PHP] str_replace on words?

[AC]

I whipped this together, it should work ok. You'll want to clean it up, 
but you get the gist.

?php
/* AC Was here */
$str=I'm going to the store to buy some stuff.;
$bold=array(store,some,stuff);
function boldWord($str,$bold) {
  if(isset($str)) {
  foreach($bold as $b) {
echo $b should be b$b/b\n;
  $str = eregi_replace($b,b$b/b,$str);
  }
  $string=$str;
  return $string;
  } else {
  $string='The inputed variable $str was empty.';
  return $string;
  }
} // End function bracket

// Example usage
if(isset($str)) {
$string=boldWord($str,$bold);
echo Original: $str \n;
echo New: $string\n;
} else {
echo Variable str not set.;
}

What is that you are actually expecting?
This is what I am using.

nl2br() [http://php.libero.it/manual/en/function.nl2br.php]

This is what is showing on the web page.
?lt;gt;prelt;gt;? print_r($ArrayName); ?lt;gt;/prelt;gt;?
This is what you are asking PHP to do.
Actually - to achieve this - it would be better to use the 'htmlspecialchars()' function 
[http://php.libero.it/manual/en/function.htmlspecialchars.php]

Anyway, probably I didn't understand what you want from your code...

Ok, first off there are builtin functions to do this kind of thing:

  http://www.php.net/htmlspecialchars 
  http://www.php.net/nl2br

Secondly, think about what your code is doing, and the order that it's
doing the replacements.

The first thing you're doing is replacing the newlines with br tags.

The second and third things you're doing will disable all the tags
including the br tags you've just inserted, by replacing '' with
lt; and ' with gt html entities;

The fourth thing you're doing is disabling the html entities by
replacing '' with amp; including the entities you've just inserted
as steps two and three.

 Hi all,
 
 I have found a problem using the str_replace() function in PHP5. Over this 
 past weekend we switched our production server to php5.0.0 running on 
 apache 1.3.31 on SUSE9.1. Our development environment is identical. I have 
 an application that runs a series of str_replace calls to drop in some 
 document title and link information into an html string before sending it 
 to the browser.
 
 Code example:
 $html_string[0] = lia 
 href=\read_docs.php?file=@@FISCAL_YEAR@@/@@month@@/393_@@TYPE@@.pdftype=pdfaction=read\GEP
 
  HIP Balances (GLC393)/a/li ;
 
 $html_output_1 .= $html_string[0];
 
 $output = str_replace(@@FISCAL_YEAR@@, $this_year, $html_output_1 );
 
 (I call it three times to do the replacements in the string).
 
 This basically produces a list of documents with links to there location 
 from a database call.
 
 On our development box this little application runs fine. In production 
 where our server is getting around 1 million hits a day (but the processor 
 is rarely above 1% usage) this function completely fails. The page just 
 doesn't get shown. If I comment out the calls to str_replace the html goes 
 over perfectly with the @@TOKEN@@ instead of the necessary information. If 
 I change the str_replace to say YEAR or FISCAL etc it makes no difference.
 
 I dropped the production server to php 4.3.8 and the str_replace() function 
 works exactly as expected and there are no problems loading the page. Bump 
 back to php5.0.0 and it coughs again.
 
 Has anyone else seen anything like this or does anyone have an explanation? 
 I can recode the series of str_replace calls but now I'm somewhat worried 
 that other solutions will also fail.
 
 It seems to me like there's maybe a load tolerance bug in php5 when running 
 str_replace() since I can't see this on our development box nor in 4.3.8.
 
 The only difference in the functions between php4 and 5 is the addition of 
 the count option, could that be the issue?
 
 Any help or comments would be greatly appreciated.

Yup, i understand not in php 5, there was some large OO changes in php
5, which is why i asked about $this-year. Ive been using php 5 for the
last year, and havent had a problem with str_replace, and have used it a
fair amount for loading email templates.   
So when you look at the source, the @@FISCAL_YERAR@@ is still in the
html lines?  str_replace did not do anything at all?

I'd wager that your script is dying because your probably running
out of memory that php is allowed to use:

 - Check the local value of php.ini:memory_limit
 - set error_reporting = E_ALL
 - ensure log_errors is on and check the logs
   or turn display_errors on

Sounds like a threading issue to me. PHP and Apache 2 don't always get
along unless you're using Apache2 in prefork mode. These things
usually don't show up except under heavy load (which it seems you
have). Check out the link below for more info:

better it most likely will be.

If I read that correctly, you want to replace $$ with /, yes?
In which case a str_replace will do that just fine. Ignore the final
letter of the string and just search for $$ and replace with a /.

Re: [PHP] Str_Replace Command

[Christopher J. Crane]

Ok I got around it by the following, but now I have a new problem. I can not
get the two dimensional array working. I want to later be able to output a
variable like this $TickerData[IKN] and it will output the associated
$Price.

  $StockURL =
http://finance.yahoo.com/d/quotes.txt?s=xrx,ikn,dankyf=sl1e=.txt;;
  $StockResults = implode('', file($StockURL));
  $Rows = split(\n, $StockResults);
  foreach($Rows as $Row) {
list($Symbol, $Price) = split(,, $Row);
   $Symbol = str_replace('', , $Symbol);
   $TickerData = array($Symbol=$Ticker);
}
  print_r($TickerData);
  echo $TickerData[IKN].br\n;

So what does the above show? If it isn't what you expect, figure out *why*. 
Like how is $TickerData being assigned.

Re: [PHP] Str_Replace Command

[Christopher J. Crane]

Well this is it and it is really got me...
Echoing out the $Symbol and $Price works just fine one row about the
$TickerData array assignment. Yet it outputs nothing.
Array ( [] = ) is what I get. If I change the line to
$TickerData = array ($Symbol = $Price); I get nothing, or the same
result. If I change the line to
$TickerData = array ('$Symbo'l = '$Price'); I get the following
Array ( [$Symbol] = $Price ) which tells me the assignment works, but it
seems like the $Symbol and $Price variable are blank when assigning to the
array. I know that they are not blank since they echoed out just fine one
line above.GRR



  $StockURL =
http://finance.yahoo.com/d/quotes.txt?s=xrx,ikn,dankyf=sl1e=.txt;;
  $StockResults = implode('', file($StockURL));
  $Rows = split(\n, $StockResults);
  foreach($Rows as $Row) {
list($Symbol, $Price) = split(,, $Row);
 $Symbol = str_replace('', , $Symbol);
echo $Symbol. - .$Price.br\n;
$TickerData = array ($Symbol = $Price);
}
  print_r($TickerData);

Are you sure that the line: echo $Symbol ...
is displaying something sensible for each $Row?

You're overwriting $TickerData at each iteration of the foreach-loop thus if 
your last $Row doesn't contain something sensible neither would $TickerData.

You probably want to use this assignment instead:

  $TickerData[$Symbol] = $Price;

why not replace:
$TickerData = array ($Symbol = $Price);

that line reassigns $TickerData to a array with one element in it
everytime you call it.  The last time through your loop, $Symbol = ''
and $Price = '', so you get Array ( [] = ) when you print_r

with this:
$TickerData[$Symbol] = $Price;

RE: [PHP] Str_Replace Command

[Crane, Christopher]

Matt:
This worked perfect. Thank you. I didn't realize it was reassigning, I
thought it would work similar to array_push and add to the existing data. I
get it now, thanks to you.

Thanks again. I had been so frustrated I was losing my objectivity.

Re: [PHP] str_replace and TABS

I'm using the following to replace certain characters but am having
troubles
with TABS. How do I find them?

$replacement = array(\, ,, ., !, ?,;, :,),(,\n);

Thanks

I think \t .  Double check with google.
