array processing


Recommended Posts

Dear friends,

      I have to process an array contents. The process is that, if  the value is string, I have to quote the meta characters in the string(quotemeta) and enclose the string in a quotation. So, I have to check every array content.


    In perl, we have grep and map to do things like this. how to perform this in php?

I think you might consider array_walk() (or foreach as in perl) as a map replacement.


PHP has a quotemeta (http://us.php.net/quotemeta), but I don't think it functions as a replacement for perl's. As the previous poster pointed out a preg_grep which functions similarly - but not exactly the same - as perl's grep functions... as I understand it at least. I'm not very experienced with perl.



$testString = '#%test%@str_ing./3';
echo preg_replace('/([^A-Za-z_0-9])/', '\\\$1', $testString);


should work similarly to perl's quotemeta.
