[Resolved] how to match " (chr x22)

pasokonkun

I have a problem i need to match " with a regex

I tried it with the escape backslash \"
and with the [\x22] ascii code

$text=preg_replace("/([\x22])/", "MYREPLACE", $text);

did not replace the "

Any ideas?

Hi,

try it with str_replace,

$text = str_replace('"',"MYREPLACE",$text);

Hello thank you for your post. unfortunately I have to use preg_replace. str_replace could work if I just wanted to replace " wit some other text, but in fact I want to make a more complicated replace, which can not be done with str_replace. I wondered why my preg_replace did not work and I found out thhat thhhe reason was a mismatch of the " (apostrophe)character. Then I tested a simplified preg_replace and realized that this also did not work. I just posted this simplified code (that also can be done with the str_replace , but I need to do it with preg_replace.

How can I do this?

Hi,

how does the complete preg_replace look like (or what do you want to replace) ?

Hello this is the complete code
which should replace bbcode quotation

These look like this:

[quote:2342423="somename"]some text [/quote]

$uid=2342423;

This is the code which does not work:

 $text=preg_replace("/(\[(?i)quote:".$uid."=\")(.*?)(\"\])(.*?)(\[\/(?i)quote:".$uid."\])/", "<br /> <table width=\"90%\" cellspacing=\"1\" cellpadding=\"3\" border=\"1\" align=\"center\"><tr><td>\$2 wrote:</td></tr><tr><td class=\"quote\"><quote>\$4</quote> </td></tr></table> <br />", $text);

This code works, but it does not look as I want it as it displays the apostrophes so I want to match the apostrophe:


$text=preg_replace("/(\[(?i)quote:".$uid."=)(.*?)(\])(.*?)(\[\/(?i)quote:".$uid."\])/", "<br /> <table width=\"90%\" cellspacing=\"1\" cellpadding=\"3\" border=\"1\" align=\"center\"><tr><td>\$2 wrote:</td></tr><tr><td class=\"quote\"><quote>\$4</quote> </td></tr></table> <br />", $text);

im not sure what you mean by wanting to match the apostrophes but i came up with this that works for replacing and setting up the html.

<?php

$uid = "2342423";
$text="[quote:2342423=\"somename\"]some text 
is gonna be here[/quote]";

$text = preg_replace("/\[quote:$uid=\"(.*)\"\](.*)\[\/quote\]/is", "<br /> <table width=\"90%\" cellspacing=\"1\" cellpadding=\"3\" border=\"1\" align=\"center\"><tr><td>\$1 wrote:</td></tr><tr><td class=\"quote\"><quote>\$2</quote> </td></tr></table> <br />", nl2br($text));

echo $text;

?>

Thank you posting the code

I copied your code into a blank file and I realized that your code worked. Something strange is, if I include it into my code it does not work anymore. Again I got the same problem, I needed to delete the \" inside the code and it worked again. Maybe I will have to look at my code a little more detailed again...

Anyway thanks alot for all your help!

Hi,

if you have still problems ... post the code that doesn't work 🙂

Mark this thread resolved if you were able to solve the problem.

The problem is solved now: it was caused by a
$text = htmlspecialchars($text);
line before the replace,

So the replace code was

$text = preg_replace("/\[quote:$uid=\&quot;(.*?)\&quot;\](.*?)\[\/quote:$uid\]/is", "<br /> <table width=\"90%\" cellspacing=\"1\" cellpadding=\"3\" border=\"1\" align=\"center\"><tr><td>\$1 wrote:</td></tr><tr><td class=\"quote\"><quote>\$2</quote> </td></tr></table> <br />", nl2br($text));

Thank you again for your help!
