Bug description: getopt parses incorrectly
Description:
------------
When parsing options, if the command line arguments are WRONG, php mangles
them in such a way as to give an incorrect, but valid response.
Eg my program normally takes arguments:
./getopt.php -a -x foo -y bar
(ie. option a takes no value; options x,y take values)
Therefore, if I run it as
./getopt.php -a -x -y bar
this is clearly a mistake: I omitted the value for -x.
HOWEVER, php assumes that I wanted the value for -x to be '-y'
If this is "a feature, not a bug", it might be worth documentig it, or
providing a switch to enable the behaviour I'd expect. Thank you.
Reproduce code:
---------------
#!/usr/bin/php
<?
$flags="ax:y:";
$options_array=getopt($flags);
echo "Here are the results of getopt:\n";
foreach ($options_array as $key => $value){
echo "\tkey:\t $key\t value is:\t $value";
if ($value===false){
echo "\t[FALSE]";
}
echo "\n";
}
echo "\n";
#N.B. If options -x and -y each expect an argument, then one might expect
# 'getopt.php -x -y foo' to result in $key="x",$value=false;
$key="y",$value="foo"
# BUT actually, the result is $key="x",$value="-y"; and foo is left over.
Expected result:
----------------
[rjn]$ ./getopt.php -a -x -y bar
Here are the results of getopt:
key: a value is: [FALSE]
key: x value is: [FALSE]
key: y value is: bar
Actual result:
--------------
[rjn]$ ./getopt.php -a -x -y bar
Here are the results of getopt:
key: a value is: [FALSE]
key: x value is: -y
