This gives me @data2 as

But I really cant access data2 by its individual elements.
$data2 is the entire list, while $data,2,3...... (1 Reply)
Hello everybody,
I'm coding a network program and i need it to "understand" ip ranges, but i don't know how to make to parse an IP CIDR range, let's say "172.16.10.0/24" to work with the specified IP range.
I've found a program which does it, but i don't understand the code. Here is the... (3 Replies)

Hi all, I would appreciate if someone could share how to convert CIDR notation to netmask and vice versa.
The value below is just an example. it could be different numbers/ip addresses.
Initial Output, let say file1.txt
Final Output, let say file2.txt (3 Replies)
Hi,
Recently I had to convert a 280K lines of ip ranges to the CIDR notation and generate a file to be used by ipset (netfilter) for ip filtering.
Input file:
000.000.000.000 - 000.255.255.255 , 000 , invalid ip
001.000.064.000 - 001.000.127.255 , 000 , XXXXX
001.000.245.123 -... (10 Replies)
2 scripts to convert IP ranges to CIDR notation using awk, gawk or mawk. The scripts are much faster than using ipcalc and will return the same results. The first script is reliably compatible with awk, gawk and mawk but is over 3 times as slow as the second script which is reliably compatible with... (38 Replies)

ereg_replace
EREG_REPLACE(3) 1 EREG_REPLACE(3)ereg_replace - Replace regular expressionSYNOPSIS
string ereg_replace (string $pattern, string $replacement, string $string)
DESCRIPTION
This function scans $string for matches to $pattern, then replaces the matched text with $replacement.
Warning
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
PARAMETERS
o $pattern
- A POSIX extended regular expression.
o $replacement
- If $pattern contains parenthesized substrings, $replacement may contain substrings of the form digit, which will be replaced
by the text matching the digit'th parenthesized substring; will produce the entire contents of string. Up to nine substrings
may be used. Parentheses may be nested, in which case they are counted by the opening parenthesis.
o $string
- The input string.
RETURN VALUES
The modified string is returned. If no matches are found in $string, then it will be returned unchanged.
EXAMPLES
For example, the following code snippet prints "This was a test" three times:
Example #1
ereg_replace(3) example
<?php
$string = "This is a test";
echo str_replace(" is", " was", $string);
echo ereg_replace("( )is", "\1was", $string);
echo ereg_replace("(( )is)", "\2was", $string);
?>
One thing to take note of is that if you use an integer value as the $replacement parameter, you may not get the results you expect. This
is because ereg_replace(3) will interpret the number as the ordinal value of a character, and apply that. For instance:
Example #2
ereg_replace(3) example
<?php
/* This will not work as expected. */
$num = 4;
$string = "This string has four words.";
$string = ereg_replace('four', $num, $string);
echo $string; /* Output: 'This string has words.' */
/* This will work. */
$num = '4';
$string = "This string has four words.";
$string = ereg_replace('four', $num, $string);
echo $string; /* Output: 'This string has 4 words.' */
?>
Example #3
Replace URLs with links
<?php
$text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]",
'<a href="\0">\0</a>', $text);
?>
NOTES
Note
As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED
notice. See the list of differences for help on converting to PCRE.
Tip
ereg_replace(3) is deprecated as of PHP 5.3.0. preg_replace(3) is the suggested alternative to this function.
