文字列に preg_split を使用していますが、必要な出力が得られません。例えば
$string = 'Tachycardia limit_from:1900-01-01 limit_to:2027-08-29 numresults:10 sort:publication-date direction:descending facet-on-toc-section-id:Case Reports';
$vals = preg_split("/(\w*\d?):/", $string, NULL, PREG_SPLIT_DELIM_CAPTURE);
出力を生成しています
Array
(
[0] => Tachycardia
[1] => limit_from
[2] => 1900-01-01
[3] => limit_to
[4] => 2027-08-29
[5] => numresults
[6] => 10
[7] => sort
[8] => publication-date
[9] => direction
[10] => descending facet-on-toc-section-
[11] => id
[12] => Case Reports
)
どちらが間違っている、それを出力したい
Array
(
[0] => Tachycardia
[1] => limit_from
[2] => 1900-01-01
[3] => limit_to
[4] => 2027-08-29
[5] => numresults
[6] => 10
[7] => sort
[8] => publication-date
[9] => direction
[10] => descending
[11] => facet-on-toc-section-id
[12] => Case Reports
)
正規表現に問題がありますが、修正できません。
