I am transitioning from php to ruby and I am trying to figure the cognate of the php commands preg_match_all and preg_replace in ruby.
Thank you so much!
The equivalent in Ruby for preg_match_all
is String#scan
, like so:
In PHP:
$result = preg_match_all('/some(regex)here/i',
$str, $matches);
and in Ruby:
result = str.scan(/some(regex)here/i)
result
now contains an array of matches.
And the equivalent in Ruby for preg_replace
is String#gsub
, like so:
In PHP:
$result = preg_replace("some(regex)here/", "replace_str", $str);
and in Ruby:
result = str.gsub(/some(regex)here/, 'replace_str')
result
now contains the new string with the replacement text.
