PHP - Find 'n Replace Doesn't Replace

I'm trying to increment a numerical value and after several hours of reading haven't come up with a solution.
this may be too much information but here it is;

I'm using this code to change the values in r5include.html

Code: [Select]
<?php $ident = $_POST['ident']; ?>
<?php
$ident2 = ($ident . 2);
$filename = 'r5include.html'; 
$string = file_get_contents($filename); 
$old = array("'images/up.jpg'","add.html' target='_blank'");
$new = array("'$ident/$ident2.jpg'","$ident.html' target='iframe2'");
$data = str_replace($old,$new,$string);
$handle = fopen($filename, "w+"); 
fwrite($handle,$data); 
fclose($handle); 
?>

but before I do that I'm copying the original to a temp file with this code:

Code: [Select]
<?php
$filename = 'r5include.html';
$string = file_get_contents($filename);
$tempfile = 'temp.html';
$handle = fopen($tempfile, "a"); 
fwrite($handle,$string); 
fclose($handle); 
?>
This is what goes to temp.html:

Code: [Select]
<img height=75 src='images/up.jpg'
hidefocus='true' usemap='#record51' />
<map name='record51'>
  <area shape='rect' coords='0,0,75,75'
href='add.html' target='_blank'>

I would like to increment the 2 instances of record51 to record52 and increment again each time the process is initiated.  And then  append it to r5include with this:

Code: [Select]
<?php
$myFile = "r5include.html";
$fh = fopen($myFile, 'a') or die("can't open file");
$filename = 'temp.html';
$string = file_get_contents($filename);
fwrite($fh,$string);
fclose($fh);
?>
So the question is is it possible? and if so how do I increment the record number? 

Thanks,

Folks,

I need to Find and Replace some words in Source HTML, which is saved in a PHP Variable.

Example:

Quote

$html = '<img src="some_source" title="paintball mask Picture" alt="Image for Paintball Mask"> <strong> Best Paintball Mask</strong>';


Find Condition: I want to FInd word "Paintball Mask" in vairiable $html, only where if the word "Paintball Mask" is there in Htaml Tag <Strong> </Strong>.  As you can observe in $html, we have "Paintball Mask" in <IMG> Tag also, i want to Skip this because I only Need to COnsider if the word "Paintball Mask" there in <strong></strong> or not.


One the words is found in <strong></strong> tag, i need to replace that word, to make it a hyperlink. (I think this bit can be done with strreplace())

But how can i restict my search to only <strong></strong> tag?



Let me give Data Again:

Quote

$html = '<img src="some_source" title="paintball mask Picture" alt="Image for Paintball Mask"> <strong> Best Paintball Mask</strong>';

Find What: Paintball Mask

Find in Which Tag: <strong> </strong>

Replace it with: <a href="/">Paintball Mask</a>



can someone help me with the code?

Cheers

I know this won't be possible with DOC, but it should be with DOCX.

Basically I want to have someone write up a docx file using special tokens in certain places.  Then my PHP would find and replace those tokens when the users needs to.  It would create and serve a NEW docx file with the tokens replaced.

Any ideas on this? I'm reading up on a ton of libraries, but nearly all of them, their examples don't work out of the box.

Thanks!

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

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!)

Im dealing with html links in a database where I need to execute a small piece of php code. Well mysql doesnt execute php code thats held in a table. The easiest way for me to do this is just add the links without the code, & set up a function that will replace anything I set to for example in my case a link lookin like this:

http://mysite.com/index.php?page=offers&blah=blah&sid=

needs to look like this;

http://mysite.com/index.php?page=offers&blah=blah&sid=<?php echo $_SESSION['login']; ?>

so I would need a function like

<?php
$replace('sid=','sid=<?php echo $_SESSION['login'];?>
?>

something like that.

And I know its possible & I could create a function like this but honestly right now I am so tired after working 12 hours im lazy dont want to think to hard while I know there are a lot of people out there that have a function like this already.

If you dont have one & dont feel like writing one for me could you atleast point me in the right direction so I dont have to think to hard?!

Thanks!!

Hi,

bit stuck on how to find and replace "<" and ">" with "&lt;" and  "&gt;". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once

here's an example below

Code: [Select]
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>

the desired output would be:

<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>

help on this would be great

Cheers

How does wordpress and other similar CMS/applications replace their div elements?

For example, if you view the source code of a wordpress site, you will only see:

Quote

<div id="header"></div>


Where, the above code is clearing being switched out for "header.php".

How is this done? I believe it's php and jquery, but I would be wrong.

Thanks!

alright, is this the correct format for a REPLACE INTO?  if not what do i need to change.......it isn't working......
Code: [Select]
$sql = "REPLACE INTO Events (name, event, eventid, userid, title1, title2, title3, title4, title5, title6, title7, title8, email)
VALUES('$name','$event','$eventid','$userid','$title1','$title2','$title3','$title4','$title5','$title6','$title7','$title8', '$email')";
 $rs = mysql_query($sql) or die ("Problem with the query: $sql<br>" . mysql_error());

User can edit a post.

I need to replace the html '<br/>' element to newline character ('\n') .

When a user will edit a post he/she will not see the '<br/>'.

How can i do this with php ?

I retrieve urls that have the following path
$url=http://cdn.test1.com
$url=http://cdn.test2.com and so on...
i want to to do a string replace such that it displays http://test.com,http://test2.com and son without the cdn part.
Will the following work for all cases?
Code: [Select]
$url=str_replace("cdn.","",$url);

Hello,

I'm trying to convert a paragraph of text which is already html formatted.

I wish to find keywords, such as, 'PHP', which are contained in the paragraph, and replace them with a link, for example <a href="http:/www...">PHP</a>

str_replace('PHP', '<A href=""....">PHP</a>', $content);


My problem arises when some of these keywords are already contained in a link, so say, visit PHP website, is all one link, so str_replace would simply convert the PHP in this string, to two links for one single word.

Code: [Select]
<a href="">visit <A href=""....">PHP</a> website</a>How could this problem be resolved?

Thanks

Hello:

I have a quick question.

I am currently using the following code to replace an apostrophe and quote marks when inserting and updating a database record:
Code: [Select]
$myPageContent = mysql_real_escape_string(str_replace("'", "&#39;", $_POST['myPageContent']));
$myPageContent = mysql_real_escape_string(str_replace("", "&#34;", $_POST['myPageContent']));

My question is - how can I modify it so I only need to use one line.
Like (but this does not work):
Code: [Select]
$myPageContent = mysql_real_escape_string(str_replace("'", "&#39;", "", "&#34;", $_POST['myPageContent']));

It seems to me that the way I am currently doing it might be POSTing the data twice?

Thanks!
