PHP - How Can I Replace 3 Specific Sections Of A String That Includes Quotation Marks?

so i have this string that i want to search on the database

My database has 3 parts city, state, country

and i have a string that is say "new york city, ny, united states"

and i want to be able to be able to look into the database but search those three sections so for example

"New York City" i would like to search under city
"NY" i want it to search under state
and "United States" i want to search under country

so basically how can i split the string  into those three sections??

hope someone can help me with this

The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it.   For example:

<?php
$str = 'some blob ~abc~ followed by ~def~';

$arr_orig = array(
	'~abc~',
	'~def~'
);

$arr_new  = array(
	'value~def~',
	'blah'
);

echo str_replace( $arr_orig, $arr_new, $str );
?>

This will echo: some blob valueblah followed by blah   But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need.   I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!)

The title says it all,..well as all u can see, there are many methods to accomplish this done but not before undergoing through a heavy tasking process. For instance,
1. Open the file
2. Reads the content of the file into array.
3. Find out the desire line of text that we want to replace.
4. Make that line of text as variable and assigns with the new data(that we want to replace) as its values.
5.open another file.
6.Write the whole contents to the file opened in 5.
7. Put the contents back to the file of original.

Can anyone contributes a better way to get this done? Like replace/delete a specific line without affecting other characters or anything therein?
Thanx.

P.S
reading and using str_replace to make the alteration always ends up in giving some kind of result beyond desired after the first round of code execution.

Hello guys i am trying to figure out how to fwrite a string for example "Recommended Settings for Service Pack" under "Current Settings for Service Pack: 5.1.2600ServicePack3Build2600". I figure i cant use line number as an argument because the file report may be dynamic so i will need to use Current Settings as an argument. Please guide me if you have any ideas..thanks:) !

auditreport 
table
ServicePackSetting
Service Pack Requirement: Fail
Current Settings for Service Pack: 5.1.2600ServicePack3Build2600   
MajorAuditandAccountPolicies   
Maximum Password Age Requirement: Fail
Current Settings for Maximum Password Age Requirement: 42   
Minimum Password Length: Fail
Current Settings for Minimum Password Length Requirement: 0

Hi Guys

I'm sure this is really simple for you experts but it's proving to be my nemesis! I have an array of words: eg.

$words = array('Apples','Bananas','Cherries');

and would like to search a string of text for these words and create link tags around them based on a simple template, <a href="#">$word_found</a>

$text = "I love eating apples and bananas but hate cherries!";

So i would like to return a string like this:

$text = "I love eating <a href=#>apples</a> and <a href="#">bananas</a> but hate <a href="#">cherries!</a>";

Now, I need it to do a case insensitive search, but just wrap tags around the words it finds, leaving the case as it was found in the string. I want to avoid using a function where I have to list all the replacements like this:

function replace_text($text){
    $replace = array('apples' => '<a href="#">apples</a>','bananas' => '<a href="#">bananas</a>');
    $text = str_ireplace(array_keys($replace), $replace, $text);
    return $text;
}

because it seems very messy and long winded. Also it's not case insensitive.

It seems like there must be a way of simply searching for the words in my array and wrapping tags around the found words.

Please can anyone help!?

Many Thanks
Dan

Hi - newbie to php - I need to search a string and possibly replace part of it.  This is how I would do it in perl:

Code: [Select]
if ($homepage) {
if ($homepage !~ /http/i) {
$homepage = "http:\/\/" . $homepage;
}
}

I have a homepage field in the database but sometimes people put the http in, and sometimes they leave it out.  In perl I can figure it out and format accordingly but it doesn't work in PHP.  I'm not sure if the first line even works in PHP.  Maybe if to say something like:

if $homepage is not equal to nothing. I'm not sure.

Any help would be appreciated.

Thanks.

You, Derp, Derpina, like this => You, Derp and Derpina like this
You, Derp, Derpina, Derpson, like this => You, Derp, Derpina and Derpison like this

Hi,


I am trying to take a string from a database and replace everything within {} with code... similar to how posting in a forum works.


so say I have "...Lorem ipsom {gallery:1} sit imet..."
it will take that string (from a DB) and replace "{gallery:1}" with "<?php gallery('1'); ?>". How can this be done? Or is there keywords I can search on to find the answer? Thank you in advance.

May I please ask one more question? About replacing a string only if it appears *after* a particular string?   I'm having trouble replacing all occurrences of "wheel" with "TIRE" but only when the word "wheel" is after this:  (W/   Example:   From this: A large wheel is shiny. Big 4 wheel truck (W/ wheel) Car with a wheel, and a small toy (w/  wheel) Four wheelers are cool   To this: A large wheel is shiny. Big 4 wheel truck (W/ TIRE) Car with a wheel, and a small toy (w/  TIRE) Four wheelers are cool     Unfortunately, I thought this worked: $fixed = str_ireplace('wheel','tire',substr($original_string,stripos($original_string,'(W')));   ...until I realized it was *cutting off* all characters up until that first '(W/'   What can be done to make this work?

Hello All,
 
I've been knocking my head against the wall for several hours trying to figure out what's going on with a simple string replace.  For the most part it is working beautifully, but if a string contains a similar but not exact match it still replaces the non match.  I was under the impression that str_replace always looks for an exact match.
 
I have custom tags that are in strings of text that are structured like:  [A_CUSTOM_HEADER] [A_CUSTOM_TITLE]  and so on.  They always start with  "[A_CUSTOM"  and end with a " ] ".  In between the start and end can be just about anything.  So my problem is if I have [A_CUSTOM]  and [A_CUSTOM_TAG] in the same text str_replace seems to incorrectly replace all the [A_CUSTOM_TAG] with the [A_CUSTOM] content and the match never happens for the [A_CUSTOM_TAG] content.
 
For example:

$content = 'Here is some text and [A_CUSTOM].  Here is more text and [A_CUSTOM_TAG]'.
$content = str_replace('[A_CUSTOM]','I have a and custom',$content);
$content = str_replace('[A_CUSTOM_TAG]','I have a, custom and tag',$content);

So running that code The [A_CUSTOM_TAG] content never gets replaced correctly, it is replaced on the first pass with the [A_CUSTOM] replacement content.  
 
I hope this make sense I'm trying to explain it the best I can.
 
I tried using preg_replace() with \b to match the whole word but didn't get anything close to the respected results...haha
 
I'm sure I'm missing something simple...or at least I hope I am.
 
Thanks in advance!

how to get the domain name of a website which includes my includes file.

The code would need to be put within my includes file so when any site includes it the file will get the sites domain. to  $currentDomain

i have tried using:

echo file_get_contents()

instead of includes but i get the same issue I get back the includes domain.

then code i have tried (in the includes file):

Code: [Select]
$curdomain1= $_SERVER['HTTP_HOST'];

$pageUR1  = ereg_replace("/(.+)", "", $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]);
$curdomain2  = str_replace("www.", "", $pageUR1);

echo "<br> 1# Current Domain: ".$curdomain1;
echo "<br> 2# Current Domain: ".$curdomain2;

I wanted to replace a strings in a large text file .. what would be the fastest way ?!

e.g the text file contains ..

INSERT INTO `subjects` VALUES (1, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (2, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (3, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (4, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (5, 'some text here', 'some text here', 'some text here');

I wanted to replace the string " VALUES (1, " with  "VALUES (" in each line ..
I'm new in PHP so any response would be much appreciated .. thanks
