QUERY_STRING with multiples appearances of the same string prefix
I have a shell script and it works pretty well to pull out the query_string contents of a single instance of router=
But if I have multiple router= strings, it only pulls out the last one.
Is there a way to pull out every router= and if there is a multple string, to egrep them together under $CISCO

I wanted to add the router= string will change on each submission. Sometimes just one router and other times there will be many. Each with a different router name.

I found a rather crude way of putting my multiple same prefix strings in a file. Any suggestions to clean this up?

I have a variable embedded in a long string called "commands" coming in on a query_string. I need to copy the string to a file with the variable $loop1 converted before it writes. Right now, it writes the varible itself instead of what it should be.

Dear All,
assume i have a file with content:
<Start>6000</Start>
<Stop>7599</Stop>
the output is:
6000
7000
7100
7200

7599
how should we use any awk, sed, perl can do this task, means to extract the uniq prefixes from the start and stop prefix.
Thanks

round
ROUND(3) 1 ROUND(3)round - Rounds a floatSYNOPSIS
float round (float $val, [int $precision], [int $mode = PHP_ROUND_HALF_UP])
DESCRIPTION
Returns the rounded value of $val to specified $precision (number of digits after the decimal point). $precision can also be negative or
zero (default).
Note
PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings.
PARAMETERS
o $val
- The value to round
o $precision
- The optional number of decimal digits to round to.
o $mode
- Use one of the following constants to specify the mode in which rounding occurs.
+--------------------+---------------------------------------------------+
| Constant | |
| | |
| | Description |
| | |
+--------------------+---------------------------------------------------+
| | |
| PHP_ROUND_HALF_UP | |
| | |
| | Round $val up to $precision decimal places away |
| | from zero, when it is half way there. Making 1.5 |
| | into 2 and -1.5 into -2. |
| | |
| | |
|PHP_ROUND_HALF_DOWN | |
| | |
| | Round $val down to $precision decimal places |
| | towards zero, when it is half way there. Making |
| | 1.5 into 1 and -1.5 into -1. |
| | |
| | |
|PHP_ROUND_HALF_EVEN | |
| | |
| | Round $val to $precision decimal places towards |
| | the next even value. |
| | |
| | |
|PHP_ROUND_HALF_ODD | |
| | |
| | Round $val to $precision decimal places towards |
| | the next odd value. |
