What's the difference between \d , [:digit:], and [0-9] in regular expression ?
Hello,
It seems that \d , [:digit:], and [0-9] are not the same.According to the regular expression reference, \d , [:digit:], and [0-9] have the same meaning, which represent a digit, but why not them work on linux?
I am very puzzled for the above, "123" should match \b[0-9]{3}\b, but why it not ?
Thanks!
Is it possible to combine a regular expression with a aritmetical expression? For example, taking a 8-numbers caracter sequece and casting each output of a grep, comparing to a constant.

<?php
echo msgfmt_format_message("en_US", "{0,number,integer} monkeys on {1,number,integer} trees make {2,number} monkeys per tree
", array(4560, 123, 4560/123));
echo msgfmt_format_message("de", "{0,number,integer} Affen auf {1,number,integer} Baumen sind {2,number} Affen pro Baum
", array(4560, 123, 4560/123));
?>
Example #2
OO example
<?php
echo MessageFormatter::formatMessage("en_US", "{0,number,integer} monkeys on {1,number,integer} trees make {2,number} monkeys per tree
", array(4560, 123, 4560/123));
echo MessageFormatter::formatMessage("de", "{0,number,integer} Affen auf {1,number,integer} Baumen sind {2,number} Affen pro Baum
", array(4560, 123, 4560/123));
?>
