Without the aid of the escape mechanism, how to put a raw string into a variable?
Hi guys and gals...
I have been racking my brains with this one and I can't find anything about it...
Consider the code and the results below:
Results on OSX 10.14.x:
As you can see saving a rawstring to disk and retrieving it again works but trying to force a rawstring without the escape mechanism fails catastrophically.
This is one of the USEFUL uses of 'cat' as it works admirably in this case but it requires I/O to do so...
I need to avoid the use of the escape mechanism inside the failing condition in case I want to __edit__ said rawstring inside any code.
I would like to know what is different about putting a rawstring into a variable using 'cat' and attempting to do so using hard coding.
Dear all,

Hello all,
I have a string var which contains formatting characters at the end, it is a string with EScape sequences at the end of it.
How can I remove them so that I only keep the 'real' text?
I tried :
var1=${var1%%\033[0m}
does not seem to do the job ....
Please help

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. |
