If you're trying to do a regular expression based search and replace,
you probably ought to use preg_replace instead of str_replace, as
str_replace doesn't parse regular expressions.
Try this one out, I think I got what you wanted to do:
?php
$file = screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg;
echo preg_replace('#(screens/)temp/(.+?)_1(_main\.jpg)#', '$1$2$3', $file);

RE: [PHP] Replace in a string with regex
Totally right on the corrections. Sorry, i did not copy paste from the source
code, I wrote here to change to other names and wrote it bad.
It should be:
$file = 'screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg';
echo $a = str_replace(array('7a45gfdi6icpan1jtb1j99o925',
'temp/',’_([0-9])’), array('test','',''), $file)
Already understand that str_replace doesn't work with regex, but not getting
any luck making one preg_replace() to my needs.
Thank you

Well, you seem to have some problems with the syntax you're using on
str_replace(). According to your script, you want to remove the
following:
7a45gfdi6icpan1jtb1j99o925- which you haven't even enclosed in quote
marks
'temp/'
’_([0-9])’- which are using weird back ticks, not quote marks
and you are trying to replace those three things with
“test” - again, not proper quote marks
”” - not proper quote marks
Afaik, str_replace() doesn't allow for text replacement using regular
expressions, for that you'd have to use something like preg_replace()
Also, make sure your strings are correctly enclosed in quote marks, and
that the quote marks you use are actual quote marks and not the accented
'pretty' ones that are offered up by word processors, etc.
A regex which would do the job would look something like this:
^([^/]+)[^_]+\/(.+)$
That should create 2 matches, one for the initial directory and the
other for the latter part of the filename.

Sure that can be done. But you will need to change the second argument

To avoid confusion, rather than something like
$1{$id}$3
Which looks really indecipherable, I'd definitely think something like
'$1' . $id . '$3'
is a lot easier to read and understand what's going on by immediately
looking at it.
As an added bonus, it'll definitely work ;)

Don't you also have to escape the $'s for the matches since it's in

Sure that can be done. But you will need to change the second argument
to have double quotes so it will be parsed by PHP.
Then I would surround YOUR variable with curly brackets to separate it
from the rest.
echo preg_replace('#(screens/)temp/.+?_1(_main\.jpg)#',
$1{$id}$3,

I am confusing and '.

If you're trying to do a regular expression based search and replace,
you probably ought to use preg_replace instead of str_replace, as
str_replace doesn't parse regular expressions.
Try this one out, I think I got what you wanted to do:
?php
$file = screens/temp/7a45gfdi6icpan1jtb1j99o925_1_main.jpg;
echo preg_replace('#(screens/)temp/(.+?)_1(_main\.jpg)#', '$1$2$3',
$file);
In the second parameter, $2 is the string you'd want to replace to
test so change '$1$2$3' to '$1test$3'.
It seems like you're having trouble with regular expressions, may I
suggest you read up on them?
http://www.regular-expressions.info/ is a pretty great free resource,
as ridiculous as the design is.
I tested this, with the double quotes and the curly braces around the
middle argument (to avoid PHP getting confused) and it didn't recognise
the matches by the numbered $1, $3, etc. I know I'm not the op who asked
the original question, but it might help him/her?
Thanks

To avoid confusion, rather than something like
$1{$id}$3
Which looks really indecipherable, I'd definitely think something like
'$1' . $id . '$3'
is a lot easier to read and understand what's going on by immediately
looking at it.
As an added bonus, it'll definitely work ;)

Well, the problem here is that when you concatenate $id containing 70 on to
'$1', you effectively end up with '$170' -- which the manual page at
http://php.net/preg-replace makes clear is ambiguous, but is likely to be
treated as $17 followed by a zero, rather than $1 followed by 70. Since $17
doesn't exist (as you don't have that many capturing subpatterns in your
pattern!), it is taken to be the null string -- leaving just the left over 0 as
the result of the replacement. QED.
The workaround for this is also given on the page referenced above, which is to
make your replacement be '${1}'.$id.
Incidentally, I don't really see the need for the $1, or the equivalent
parentheses in the pattern -- since a fixed string is involved, why not just
use it directly in both places? Like this:
preg_replace('#screen/temp/(.+?)_1(.+?\.jpg)#', 'screen/'.$id, $file);
which completely sidesteps the problem.
