array processing

[nagalenoj]

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?

can you explain the function of grep?

 

I found this: http://us.php.net/manual/en/function.preg-grep.php

 

always take a look at: www.php.net, it is your best friend!

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.

 

edit:

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

 

should work similarly to perl's quotemeta.
