[PHP] ereg_replace to preg_replace translation

[m a r k u s]

Hi all,

I see that from PHP 5.3.0 ereg_replace() function is deprecated and throws a 
warning.
I would like to use the preg_replace() function as an alternative of ereg_replace() function but... 
can't undestand the \n#[^\n]*\n expression.


$sql = ereg_replace(\n#[^\n]*\n, , $sql);

Any help for tranlation or alternative ?
Thanks

Here's a good regex tutorial:  http://www.regular-expressions.info/

But to answer your question, \n#[^\n]*\n means the match must:

start with a newline(\n) followed by a pound sign (#) followed by 0 or
more characters (*) that are not a newline(^\n) all the way up to
another newline (\n).

To translate to preg I think all you need to do is give it delimiters,
but that may not be necessary, not sure. |\n#[^\n]*\n|

 $sql = ereg_replace(\n#[^\n]*\n, , $sql);

Generally the only change you need to make for transition from ereg to preg 
(for simple expressions, anyway) is the addition of pattern delimiters. So the 
above becomes, for example:

  $sql = preg_replace(|\n#[^\n]*\n|, , $sql);

Although I would argue that those \ characters should be escaped (and should 
have been even for ereg), so the more correct version of this is:

  $sql = preg_replace(|\\n#[^\\n]*\\n|, , $sql);


Cheers!

If the time covers only the conversion then it's quite terrible.

Looking at the convertTextString() function below there's a few
obvious optimizations waiting to be done, and... turning the foreach
into a single preg_replace_callback() is the one that begs
implementing the most (the code below's been tested and works):

class convertor

const SI_to_Imperial = 0;
const Imperial_to_SI = 1;

function convert($amount, $unit, $direction)
{
return sprintf(
whatever '%s' of '%s' is in the Imperial system
  , $amount
  , $unit
);
}
}
function callbackSI2IS(array $SIspec)
{
return convertor::convert(
$SIspec[1]
  , $SIspec[2]
  , convertor::SI_to_Imperial
);
}

$p = '~

 # this function takes a text string, searches for numbers to

Re: [PHP] ereg_replace with user defined function?

[Frank Arensmeier]

Thanks again for your suggestions.

Actually, - believe it or not - I have never written a class (I am  
still learning PHP after three years working with that language). So  
I am not quite sure of the benefits of your class. One thing I do  
realise is the benefit of replacing the foreach loop with a single  
preg_replace_callbak. Let me try to sum up:


With a preg_replace_callback I am able to look for a pattern like: a  
number ( float or integer ) followed by whitespace followed by one,  
two, three or more characters, followed by a closing character.


e.g.: ((\d{1,10}[,|.]*\d{0,10})*(\s)(\D{1,3})([$|\s|.|,|\)|/]+|  
$)) (untested)


If preg finds a match, it will pass an array to the specified  
function. In that function I evaluate the unit, see if it is in my  
array containing the conversion table. If that is the case,  
calculate the new value and return everything. Right?


I will get back with this new approach.

BTW, 0.32/0.34 seconds includes: calling the original html page from  
an outside server, loading this page into the DOM parser, walking  
through every table and every text string on that page. Convert  
everything necessary (the converter array contains about 14 metric -  
imperial converters) replace all converted DOM nodes and output  
everything. The metric / imperial calculations / replacements take  
between 0.00054 and 0.005 seconds per table cell / text string.

[PHP] ereg_replace with unser defined function?

[Frank Arensmeier]

Hello all.

Is it possible to have a user defined function for the replacement  
within an ereg_replace (like preg_replace_callback)? I am working on  
a script that converts html pages with metric data into imperial  
data. My script takes text strings containing one or more instances  
of e.g. 123 mm, 321 mm, 123 kg, 123 cm2 and so on. The script  
searches the string with a pattern like:

([[:digit:]]+|[[:digit:]]+\.[[:digit:]]+)([[:blank:]]?)(mm)

When the script finds an instance, it stores the matches into an  
array - ereg ( $pattern, $textstring, $matches )


The replacement (for mm) looks like:
round ( ( $matches[1] * 0.039370079 ), 1 ) . $matches[2]  . in

Everything is working great accept when the string contains more than  
one instance for example of the metric unit mm. In that case, all  
instances of xy mm will be replaced with the first occurrence.


So, a text like:

The product is 230 mm tall, 120 mm thick and 340 mm wide will  
output as The product is 9.1 in tall, 9.1 in thick and 9.1 in wide  
- because the replacement string is based / calculated on the first  
occurrence 230 mm.


Alternatively, is there a way to limit ereg_replace to only replace  
one instance at a time?


Hopefully I am not too confusing...

regards,

/frank

ps. of course I have searched the manual and asked Google - no luck ds.

Re: [PHP] ereg_replace with unser defined function?

[Ilaria De Marinis]

Hi Frank,
I think preg_replace_callback is a good solution for you.

If you don't want to use it, you can construct two arrays defining 
matches and replacements.


For example:
$matches
[230]
[120]
[340]

$replacements
[9.1]
[replace2]
[replace3]



After you stored matches in $matches using regular expression like 
yours,/preg_match_all 
http://it.php.net/manual/en/function.preg-split.php/ 
(([[:digit:]]+|[[:digit:]]+\.[[:digit:]]+)([[:blank:]]?)(mm), $string, 
$matches, PREG_SET_ORDER)


you can define $replacements by this way:
for(int =0; icount($matches); i++){
   $replacements[$i]=round((substr($matches[$i][0], 0, 
3))*0.039370079),1); //take the last part of match with no digits, I 
don't know if there are sure 3 digits

}

for(int i=0; icount($matches); i++){
   preg_replace($string, $matches[$i][0], $replacement[$i].in);
}

hope to help you

Re: [PHP] ereg_replace with user defined function?

[Frank Arensmeier]

Thank you Ilaria and Roman for your input. I did not know that preg  
is able to deal with PCRE patterns. As a matter of fact I came up  
with the following solution (if someone is interested):


the function takes a text and an array with converters like:

$converters[] = array (	metric = mm, imperial = in, ratio  
= 0.039370079, round = 1 );
$converters[] = array (	metric = m, imperial = ft, ratio  
= 3.280839895, round = 1 );



function convertTextString ( $text, $convertTable )
{
	# this function takes a text string, searches for numbers to  
convert, convert those numbers and returns

# the complete text again.

	if ( !ereg ( [[:digit:]], $text ) ) // if the text does not  
contain any numbers, return the text as it is

{
return $text;
}

foreach ( $convertTable as $convertKey = $convertUnit )
{
		$pattern = ((\d{1,10}[,|.]*\d{0,10})*(\s)(%s)([$|\s|.|,|\)|/]+| 
$)); // this regex looks for a number followed by white space,  
followed by the metric unit, followed by a closing character like  
., , or )

$pattern = sprintf ( $pattern, $convertUnit['metric'] );

while ( preg_match ( $pattern, $text, $matches ) )
{
			$matches[1] = str_replace ( ,, ., $matches[1] ); // in case  
numbers are written like 6,6 m, we need to replace , with .
			// because we do not want to return 0, we have to make shure that  
the new value is not zero.

$itterator = 0;
do {
$value = round ( ( $matches[1] * $convertUnit['ratio'] ),  
$convertUnit['round'] + $itterator  );

++$itterator;
} while ( $value == 0 || $itterator == 10 );

$replacement = $value . $2 . $convertUnit['imperial'] . 
$4;
$text = preg_replace ( $pattern, $replacement, $text, 1 
);
}
}
return $text;
}

Hi Frank,
I think preg_replace_callback is a good solution for you.

If you don't want to use it, you can construct two arrays defining  
matches and replacements.


For example:
$matches
[230]
[120]
[340]

$replacements
[9.1]
[replace2]
[replace3]



After you stored matches in $matches using regular expression like  
yours,/preg_match_all http://it.php.net/manual/en/function.preg- 
split.php/ (([[:digit:]]+|[[:digit:]]+\.[[:digit:]]+)([[:blank:]]?) 
(mm), $string, $matches, PREG_SET_ORDER)


you can define $replacements by this way:
for(int =0; icount($matches); i++){
   $replacements[$i]=round((substr($matches[$i][0], 0, 3)) 
*0.039370079),1); //take the last part of match with no digits, I  
don't know if there are sure 3 digits

}

for(int i=0; icount($matches); i++){
   preg_replace($string, $matches[$i][0], $replacement[$i].in);
}

hope to help you

Hello all.

Is it possible to have a user defined function for the  
replacement  within an ereg_replace (like preg_replace_callback)?  
I am working on  a script that converts html pages with metric  
data into imperial  data. My script takes text strings containing  
one or more instances  of e.g. 123 mm, 321 mm, 123 kg, 123  
cm2 and so on. The script  searches the string with a pattern like:

([[:digit:]]+|[[:digit:]]+\.[[:digit:]]+)([[:blank:]]?)(mm)

When the script finds an instance, it stores the matches into an   
array - ereg ( $pattern, $textstring, $matches )


The replacement (for mm) looks like:
round ( ( $matches[1] * 0.039370079 ), 1 ) . $matches[2]  . in

Everything is working great accept when the string contains more  
than  one instance for example of the metric unit mm. In that  
case, all  instances of xy mm will be replaced with the first  
occurrence.


So, a text like:

The product is 230 mm tall, 120 mm thick and 340 mm wide will   
output as The product is 9.1 in tall, 9.1 in thick and 9.1 in  
wide  - because the replacement string is based / calculated on  
the first  occurrence 230 mm.


Alternatively, is there a way to limit ereg_replace to only  
replace  one instance at a time?


Hopefully I am not too confusing...

regards,

/frank

ps. of course I have searched the manual and asked Google - no  
luck ds.

[PHP] ereg_replace help

[Richard Davey]

Hi all,

I'm sure this is blindingly simple, but could anyone tell me how to
get an ereg_replace() to return a string where all characters OTHER
than alpha-numerics have been stripped out?

I can do the reverse with:

$output = ereg_replace('[[:alnum:]]', '', $string);

Which will happily remove all alpha-numeric characters from $string!
But I want it to remove anything but.. suggestions please?

The ^ is NOT (when the first character in a bracketed character set). So
anything NOT alphanumeric is replaced.

Nope, because in the only reference book I had to hand it said the ^
matched the start of a string so it didn't occur to me to try it.

Thanks to John I now know when used in a block it's no longer limited
to the start of the string. The code you posted above works, thanks.

The '^' has a totally different meaning inside a character class than 
its meaning outside the class.  It's not a amtter of it being limited 
so much as just different (actually I guess overloaded is the real 
term).

If it's a plain simple string replace you want then use str_replace().

You can't use ! because it's not a valid special character in regular
expressions.  It's really hard to craft do-not-match-this-word patterns.
You're better off separating the two pieces of logic.

$arr = array(
abcd - rst,
abcd - uvw,
abcd - xyz,
foobar - rst,
blah - rst,
googol - uvw
);

reset($arr);
while (list($key, $value) = each($arr))
{
if (substr($value, 0, 5) != 'abcd ')
{
$arr[$key] = ereg_replace('^(.*) - .*$', '\1', $value);
}
}

Possibly have to do a if statement, ereg for the abcd and then if ture, do 
your ereg replace? I can't logically think how that would work in one regex, 
since you want to match first and then replace...but my regex skills aren't 
top notch either :)

thanks for everyone's help... 

 How do you mean its part of your code library?

I mean that the function I'm having to call is passed an array (coming from
a databse) and it has an option to do an ereg_replace() on the incoming
array. Due to the amount of other code relying on it, is very hard to change
without causing something strange to happen elsewhere :(

If all the code was mine, then I wouldn't have any reservations on changing
it in an instant. I'm having to improve the code gradually (good luck to me)

Unless you want ANY white space (\n, \t, etc) instead of just spaces, 
an ereg would be better.  I prefer preg_replace():

pages, not related to the functions), you can see that it is rather
thorough.

The biggest disadvantage  with preg is that since it is complex,
mistakes can easily be overlooked.

Only since 4.2.0 has preg_* functions been compiled by default so
if a person wanted to write scripts that were portable across many
different hosting sites  they would use ereg_* functions.

As for being deprecated, I doubt that will happen (as
mentioned above) ereg_* has been around for many years, since early
3.x versions.  Php developers may be familiar with the posix syntax
so instead of learning the perl version they have the option to use
the ereg_* functions.

Although I haven't heard any (php) claims as such but some people may want
to be 100% POSIX compatible :)

 I'm trying to replace singel line comment with empty string.

 tried ereg_replace(//.+\n,'',$string); but this replaces all text after
 //.

 anyone now what to do?

 \n is the newline character, making the string apear to be multiple lines
see the thread [PHP] multi line regular expression? and see if that
helps you any.

[PHP] ereg_replace question

[Todd Cary]

I have a string,

D:\Htdocs\gilardi\barcode\php\testwrite.php

from

 $fullpath = $HTTP_SERVER_VARS[PATH_TRANSLATED];

I want to remove the "testwrite.php" leaving

D:\Htdocs\gilardi\barcode\php\

This does not work

 $fullpath = $HTTP_SERVER_VARS[PATH_TRANSLATED];
 $fullpath = ereg_replace("\\[^\\]+$","",$fullpath) . '\\';

What have I missed?

hi,
i tried to implement the code, but it does not work if the string:

a) doesnt contain any pre../pre
b) doesnt contain any pre
c) doesnt contain any /pre
d) contains multiple pre../pre's

so i altered it a little and this is what i came up with:

Here's my original function, now tested and bugs removed, together with
some comments:

function remove_br_in_pre($string)
{
$re1 = '/(.*?)pre(.*?)\/pre(.*)/is';
$re2 = '/br\n?/is';

// setting a variable to null defines it, so we don't get
// a warning for an undefined variable at the first concatenation.
// unset($result) doesn't define it, and is unnecessary
// as it is not set at this moment.
$result = null;

// this generates a loop that will remove multiple pre's
while ($string) {

// my original assignment ($arMatch = preg_match(...)) was wrong.
// preg_match returns 1 on match, and 0 on no match.
if (preg_match($re1, $string, $arMatch)) {
$result .= $arMatch[1];

// sorry, forgot to keep the pre/pre pairs...
// you need to add a line break instead of the br
// to keep your code formatted
$result .= 'pre'.preg_replace($re2, \n, $arMatch[2]).'/pre';
$string = $arMatch[3];
}
else break;
}

// if there are no pre/pre pairs, $string will be unmodified and the
// loop will immediately break out at the first attempt. This appends
// either the whole $string, or the remaining $string, to the result.
$result .= $string;
return $result;
}

now, i've tried it in a few different scenarios and it seems to be working, 
although the function might be redundant and far from pretty - it gets the 
job done. however, i have a question; what does the is in //is denote? ;-) 
(doesnt it feel great to have code sniplets you have no idea what they do in 
your scripts? ;-))

The regex modifiers:
   i - make that case independent, so pre, PRE, and others are matched
   s - treat the input as a single line, don't stop at a newline

also, do you see any direct bugs slash features in the current function? 

Not that I'd be aware of...

thanks in anticipation,

You're most welcome :)

[PHP] ereg_replace();

[Gustaf Sjoberg]

Hi,
i'm trying to replace every instance of br within the pre../pre tags. i want 
all other breakrows to remain the same.

i've tried numerous regular expressions, but i can't find a way to just replace the 
breakrows.. it replaces _everything_ bewteen pre and /pre.

example $string:

testbr
testbr
testbr
pre
testingbr
testingbr
/pre
testbr
testbr

i want that to look like:

testbr
testbr
testbr
pre
testing
testing
/pre
testbr
testbr

You need a two-phase operation on this:

1) isolate all pre/pre elements
   preg_match('/(.*?)pre(.*?)\/pre(.*)/is', $string, $armatch);

$armatch now contains:
   [0] all, ignore this
   [1] everything before pre
   [2] everything within pre/pre
   [3] the rest after /pre

2) go on and replace all br's here:
   preg_replace('/br\n?/is', \n, $armatch[2]);

The whole stuff would look something like

/* UNTESTED */
function kill_br_within_pre($string)
{
$re1 = '/(.*?)pre(.*?)\/pre(.*)/is';
$re2 = '/br\n?/is';
$result = null;

while ($string) {
$armatch = preg_match($re1, $string, $arMatch);
if (is_array($arMatch)) {
$result .= $arMatch[1];
$result .= preg_replace($re2, \n, $arMatch[2]);
$string = $arMatch[3];
}
else break;
}
$result .= $string;
return $result;
}

This assumes that all pre are properly closed with /pre. As said, I
didn't test, but it should work this or a similar way.

[PHP] ereg_replace()

[Liam MacKenzie]

Hi guys,

I'm looking to get a specific bit of data out of a slightly complex amount
of data.
Ok, I have this in a variable:

User : [EMAIL PROTECTED]
Dir : /home/eXtremail/mbox/i-redlands.net/3/1/liam
Forward :
Copy :
Account mapping :
User Disk Quota : 0
Disk Space Used : 0
Max In Mail Size : 0
Max Out Mail Size : 0
Autoreply : No
Mailbox Access : POP,IMAP
Created : Sat Jul 6 09:21:23 2002
Status : Enabled


This is different for every user as you can see.  For instance, the Dir is
different for everyone, such is the Created date.
I need to extract the User Disk Quota and the Disk Space Used variables out
of this.  How would I go about doing that?

Is there an easier function to use than ereg_replace?

Thanks in advance!
Liam

[PHP] ereg_replace problems

[Zac Hillier]

I'm trying to replace values within a string with a value looked up from a database. I 
have a function that looks up the value in the database for me but I'm having trouble 
passing the value to the function because of  the backslashes, is there a way around 
this?

Code:

$cntnt = eregi_replace(\[L=([a-zA-Z]+)].([a-zA-Z]+)\[EL], a href=\ . 
fndLnk(\\1) . \\\2/a, $cntnt);

fndLnk is the function and the error I receive is -

Warning: Unexpected character in input: '\' (ASCII=92) state=1 

Thanks for any help

Zac

Re: [PHP] ereg_replace problems

[Analysis Solutions]

Zac:

 $cntnt = eregi_replace(\[L=([a-zA-Z]+)].([a-zA-Z]+)\[EL], 
 a href=\ . fndLnk(\\1) . \\\2/a, $cntnt);

Put \\1 in double quotes so it gets evaluated as a substring.

  a href=\ . fndLnk(\\1) . \\\2/a, $cntnt);

Enjoy,

Ok, what i wanna do is replace the codes in html with ascii equivalents:

$text= ereg_replace('#([0-9]+);' , chr('\1') , $text);
But somehow it doesnt work, i have no idea why.

When i use
$text= ereg_replace('#([0-9]+);' , '\1' , $text);
it replaces everything correctly

But
$text= ereg_replace('#([0-9]+);' , chr('\1') , $text);
just replaces everything with an empty string

Not sure what you mean here
$text= ereg_replace('#([0-9]+);' , chr('\1') , $text);

should replace for example #65; with chr('65') (\1 means everything in
brackets in regular expression), which is 'A'   .

RE: [PHP] ereg_replace or chr bug?

[Rick Emery]

chr() expects you to pass it a numeric value.  You are passing it a string.
For instance,
if $text= #45, then you are trying to do:  chr(45), which is not the
same as chr(45).
Hence, ereg_replace() fails and simply returns the original string, $text.

Not sure what you mean here
$text= ereg_replace('#([0-9]+);' , chr('\1') , $text);

should replace for example #65; with chr('65') (\1 means everything in
brackets in regular expression), which is 'A'   .

 It replaces one (1) character, not a string

 Ok, what i wanna do is replace the codes in html with ascii equivalents:

 $text= ereg_replace('#([0-9]+);' , chr('\1') , $text);
 But somehow it doesnt work, i have no idea why.

 When i use
 $text= ereg_replace('#([0-9]+);' , '\1' , $text);
 it replaces everything correctly

 But
 $text= ereg_replace('#([0-9]+);' , chr('\1') , $text);
 just replaces everything with an empty string

[Ando]

Uh why do you think that?
Try
print chr(65);
works the same as as
print chr(65);

[PHP] ereg_replace Help

[lists]

Hi all,

I have a large file that I am trying to parse.

I have a many lines that look like this


\\text1

I need an expression that will change \\text1 to text1=

so if I have something like this

\\text1 

asdfkjaslkfj
asdlfkjasljkf
asdlkfjasldfkj
asldkfjalskfj

\\text2 
erweiurwoeir
werqwer
qwer
qwerqw
er

\\text3

asdlfkw
xcvsdf
zxcvcgn
sdfgwr
xcdfvszdfg


it will become

text1 = 

asdfkjaslkfj
asdlfkjasljkf
asdlkfjasldfkj
asldkfjalskfj
 text2 = erweiurwoeir
werqwer
qwer
qwerqw
er
 text3 = asdlfkw
xcvsdf
zxcvcgn
sdfgwr
xcdfvszdfg



Any Ideas,
Michael

[PHP] ereg_replace

[Mitch Tishaw]

I need a little help with the ereg_replace function.  I have the following code:

$text = ereg_replace([[:alpha:]]+://[^[:space:]]+[[:alnum:]/],a href=\\\0
\\\0/a, $text);

which pads a url with an href tag to make it clickable.  Here's what I would 
like to do:  In the case of the url ending with .gif or .jpg, I would like to 
pad it with an img src tag instead, so it shows up as an actual picture.  Does 
anyone know how I can modify the above code to do this?  Thanks in advance.

This will not necessarily work every single time, nor will it ONLY work 
on images, but I tried -- maybe it can help you.  So why don't you test 
it out on maybe ten or so different image URLs.  If it works, go with 
it, but I accept no liability.  (Also, this regex has not been optimized 
for speed -- sorry, I don't have time to play with it.)

$text = http://www.domain.com/directory/images/image.jpg;
preg_replace((http://[^\s]+[-a-zA-Z0-9_/.]+\.(gif|jpg|jpeg)$), img 
src=\\1\ /, $text);

 Martin

Actually, implode() will take its arguments in either order, so
there's really only one thing (the comma) which could be causing
the problem.

Also, for the original poster: if you only need to do simple 
string replacements, you should see whether str_replace() will
serve your purpose. It's much less expensive than ereg_replace().
If you feel that you require regular expressions, the preg_*()
functions are less expensive than the ereg_*() equivalents.

 variablethis must also be variable/a
 
 by:
 
 font size=2a class=mn href=whatever is here should be left her and
 is variablethis must also be variable/a/font
 
 So the two tags should be placed before and after the link when a link is
 in my $pagecontent
 
 I know it's easier to use another class, but for the moment that's not an

   returns - this is first :end: middle :start: last

   but I want - this is first middle this is last

The problem seems to be that ereg_replace is being greedy on the match and matching as 
much as it
can 
instead of just finding the first match, handling that and then going on to the next 
match.

I can get it to work with preg_replace i.e. 

preg_replace(':start:(.*?):end:','this \\1',':start first :end: middle :start: last 
:end:')

   returns - this is first middle this is last 

But my actual string is on multiple lines, and preg_replace doesn't seem to continue 
trying
to match on the next line, whereas ereg_replace happily treats newlines just like any 
other
character.

So how do I stop ereg_replace being greedy or alternatively get preg_replace to treat 
multiple 
lines as a single source string?

look into the s modifier...it makes a dot match a newline as well, where

Hi,

Re: [PHP] ereg_replace - How do I stop it being greedy?

[George Whiffen]

Thanks Jack,

preg_replace with an s modifier works a treat.

I'm still curious as to how to get ereg_replace to work as well.  Everything
I read about regex/Posix Regular Expressions, seems to suggest that a ?
should also work with ereg_replace!

Not exactly what you wanted, but you could do

implode(+, explode( , $home_street));

Re: [PHP] ereg_replace

[Rasmus Lerdorf]

Use the urlencode() function.

Or at the very least use str_replace.

And by the way, the ereg_replace() you have works fine.  You must be doing
something silly.

Hi,

short question:

i want to use ereg_replace to replace something with an array-element,
this is my code and its not working:

ereg_replace(\\$([0-9]), \$parmarray[\\1], $string);

parmarray is of course an array with some elements,
Here are the facts:

$parmarray = array (, value1, value2);
$string = foo $1 bar $2;



output: foo $parmarray[1] bar $parmarray[2]

i want of course:

I think, begining from some php 4, preg_replace allows to do this,
Otherwise, you could use preg_match to find first match then strpos() to
find it position, and, finaly substr() with concatenation to your
replacement. This loong way was the first, that came to my mind for cases,
where regexp realy needed. (If they are not needed, str_replace() would
work faster/simlier, you know o'cos:). 

Note: for some strings I experience hangup, especially  w/ereg_replace,
but also, for long ones, w/preg0. Regards. Leonid.

[PHP] ereg_replace: Help!

[Erica Douglass]

I have one ereg_replace problem that I cannot seem to fix.

I need to delete an IMG tag. The only thing I know about this tag is that 
it will contain

SRC=images/headers

in the string. Here is an example:

IMG ALT=Tools BORDER=0 HEIGHT=55 SRC=images/headers/tools.gif WIDTH=455 

I tried this, but it didn't work:

$contents = ereg_replace (IMG.*images/headers.*, , $contents);

Can someone please help?

Re: [PHP] ereg_replace

[John Vanderbeck]

 why does this

 ?php
 $string = "this is my string.";

 print $string . "br\n";

 $string = preg_replace(
 array( '/is/', '/string/'),
 array( 'is not', 'bit of text' ),
 $string
   );

 print $string . "br\n";
 ?


This happens because you are replacing  "is" with "is not" so parse your
string by hand:

"this is my string"..ok the first occurence of "is", is in the word "this",
so do the replace..the replaced part in CAPS:
"thIS NOT" .. then the second "is":
thIS NOT IS NOT" etc..I think you can see why now..

You could specify word boundaries on each side of your string
to get the behaviour you were expecting.

 $string = preg_replace(
 array( '/\bis\b/', '/\bstring\b/'),
 array( 'is not', 'bit of text' ),
 $string
   );

No, not really. \b matches the start or end of a word. You can see it
clearly if you do this:

   print preg_replace( '/\b/', '-', 'this is a string' ) . "br\n"; 


It will output:

   -this- -is- -a- -string-

As it replaces all the word boundaries with a hyphen.

So the regular expression /\bis\b/ will match only the word 'is'
and not 'this' or 'isotope' or 'biscuit'.

With ereg_replace it must be done seperately, but if you use
preg_replace you can pass it a list of replacements. like this:

?php
$string = "this is my string.";

print $string . "br\n";

$string = preg_replace(

RE: [PHP] ereg_replace

it replaces 'This' with 'That', some you tell to ereg what he should think
'This' is and what to replace it with.

It does only one replacement at a time.

[PHP] ereg_replace with assoc array?

[Jaxon]

Hi

Can I do this

$string = file.tpl;

while (list($pattern, $replacement) = each($array)) {
ereg_replace ($pattern, $replacement, $string);
}

echo $string;



note some assumptions below:

$array contains an assoc array:

first  foo
second bar
third  rab
fourth oof

file.tpl is this:

some html {first} 
more html {second}
even more html {third}
lots more html {fourth} 

This seems like a slow way to do this...
any advice is welcome!

tia!

[PHP] ereg_replace all items in a array

[Joseph H Blythe]

G'day PHP'ers

I am trying highlight the results from a search, so far I have this working but only 
if the string is an exact match ie: case sensitive, for example:

?php
$keywords = "foo";
$data = "This is a lower foo. This is an upper FOO. This is a ucase Foo";

$lower = strtolower($keywords);
$upper = strtoupper($keywords);
$ucase = ucwords($keywords);
$words = array($lower, $upper, $ucase);

while ( list($key, $val) = each($words) ) {
$hilite = "font color=\"#ff\"" . $val . "/font";
$replaced = ereg_replace($val, $hilite, $data);
}

echo $replaced;
?

Now as metioned this seems to work only for "foo" does anyone have any idea why? 

Also I need to be able to support mutiple keywords ie: foo Foo FOO, so basically I 
know I could split(" ", $keywords) then some how traverse the array making a new array 
of all possible case combinations then in my while loop replace each occurance found 
in $data with the highlighted replacment, sounds easy hmm

If anyone has any ideas or can see what I am doing wrong so far, it would be mutch 
appreciated.

Regards,

Joseph

Re: [PHP] ereg_replace all items in a array

[Jeff Warrington]

In article [EMAIL PROTECTED], "Joseph H
Blythe" [EMAIL PROTECTED] wrote:

What is happening is that you are replacing the variable $replaced
on each iteration of the while loop. As a result, $replaced is only
storing the most recent match.

To see this, try this out:

$keywords = "foo";
$data = "This is a lower foo. This is an upper FOO. This is a ucase Foo";

$lower = strtolower($keywords);
$upper = strtoupper($keywords);
$ucase = ucwords($keywords);
$words = array($lower, $upper, $ucase);

while ( list($key, $val) = each($words) ) {
print("key: $key = val: $valbr");
$hilite = "font color=\"#ff\"" . $val . "/font";
$replaced[] = ereg_replace($val, $hilite, $data);
}
for($i=0;$isizeof($replaced);$i++) {
echo $replaced[$i]."br";
}

The first print statement will show you what keywords we are
focusing on. The ereg_replace in this case is appending an arrary.
If you then walk that array, you will see that each of your keywords
was matched and highlited.  

that should get you a little further along.
