Regular expression question 1

[svar]

Can one use str_replace to do this:

$string=' AND VALUE=..... AND .....';

should end up removing the leading AND

In perl this would be

$string=~s/^\s+AND//

or

$string=~s/^AND//

(yes, it can be do in one statement) to remove a leading 'AND' and possibly any whitespaces(blancs) before it.

or giving us an answer?

(yes, it can be do in one statement)

Hi

Use [tt]preg_replace()[/tt] :

[COLOR=#6666FF]$string[/color] [COLOR=#008080]=[/color] [COLOR=#FF6600]preg_replace[/color][COLOR=#008080]([/color][i][COLOR=#009900]'/^\s+AND/'[/color][/i][COLOR=#008080],[/color] [i][COLOR=#009900]''[/color][/i][COLOR=#008080],[/color] [COLOR=#6666FF]$string[/color][COLOR=#008080]);[/color]

Thanks. If $string does not start with \s+AND, I assume this will not change anything, correct?

Hi

Correct. PHP's [tt]preg_*()[/tt] functions use the PCRE ( Perl-Compatible Regular Expression ) library, so you can expect the behavior you are used with from Perl.
