The string is "<td>charge</td><td>100</td>".
I want and array( "charge"=>100).
I am using this regular expression,
'/<td>([^<]+)<\/td><td>(?P<\1>\d+)<\/td>/'.
But its not working..
I get this error.,
PHP Warning: preg_match(): Compilation failed: syntax error after (?P
at offset 25 in E:\src\php\WebEngine\- on line 4
any idea?
it seem's everybody is giving you the same answers; here's a definitive
look at the problem (as far as I'm aware)
all preg_* functions can only return back string's, or array's of
strings; there is no method of returning back an associative array as
you would like; the closest you can get is by using preg_replace or
preg_replace_callback as follows:
print_r( preg_replace_callback('|<td>(.*)</td><td>(\d+)</td>|',
create_function(
'$matches',
'return array($matches[0],$matches[1]);'
), $string) );
this will fall as the internals of preg* casts the array to a string
alternative:
print_r( preg_replace('|<td>(.*)</td><td>(\d+)</td>|e',
'array("$1","$2")', $string) );
this will also fail as the internals of preg* casts the array to a string.
similarly all other options you could go down such as simple explodes,
strip_tags or even more complex stream filters will only allow you to
return strings, or numerical array's of strings.
This leaves you high and dry I'm afraid - the only thing for it is to
create a simple function to handle this for you; something like
function td_thing( $string ) {
$a = preg_replace('|<td>(.*)</td><td>(\d+)</td>|e', '$1 $2', $string);
$b = explode(' ', $a);
return array("$b[0]" => "$b[1]);
}
maybe just maybe you or I or somebody else can find a way to do this
easily in one line; but for now a function similar to above is the best
you can do..
