[SOLVED] Easy one

[AV1611]

I have a table and a field has a bunch of entries with backslashes (\) from some other script.  I want to clean them all out.

the bs's are not all in the same place

example entry:

buzz\_bait    --->    buzz_bait

\[HENRY\]    --->    [HENRY]

etc...

I don't think subst() will do it because the bs's are in different position each time... can someone suggest the right function/command to use in PHP?

have you tried stripslashes?

stripslashes() won't do the job here- because it doesnt remove the slashes from things like underscores or "[".
You can use this function- $string should be the string that you want to remove the slashes from, and escaped should be an array containing all of the chars that got escaped and you want to un-escape.

[code]<?php

function unescape($string, $escaped)
{
$b_slash = "\\";
foreach($escaped as $char)
$string = str_replace($b_slash.$char, $char, $string);

return $string;
}


$replace = array("[", "]", "&", "#");
$string = "\\[Hello\\] \\& \\% \\' \\#"; //I've escaped the backslashes because I have to, not for the test
echo $string;
echo "<br>";
echo unescape($string, $replace);


/*
Output:
\[Hello\] \& \% \' \#
[Hello] & \% \' #
*/

?>[/code]

Orio.

actually I did it like this

[code]
$replace="\\";
...
$aa=$row[0];
...
$aa=str_replace($replace,"",$aa);
...
[/code]

BTW thanks for the answer...

Well I just tested this..

[code]
<?php
$string = 'this is\_a \[test\]';

echo stripslashes($string);
?>
[/code]

The output was this is_a [test].

This worked fine.. it removed all \ s from the string.. I tried in several different ways all with the same out come..

So I guess, unless I missed something, that stripslashes would work fine..
