I have this problem in out project
$line = substr($line,8);
$LIT_YARN = '".*"';
$VAR_NAME = '[A-Za-z][a-zA-Z0-9]*';
$TEMP2 = "/($LIT_YARN|$VAR_NAME)/";
$line = trim($line);
preg_match_all($TEMP2,$line,$params);
var_dump($params[0]);
the simple input is
" "askdj" "asjdk" "asdasndw" "
the complicated input is
" "asd" Y "asd" X "
variables can also be inputted
simple input resulted to a single string
params[0] => "askdj" "asjdk" "asdasndw"
I was expecting like this
params[0] => "askdj"
params[1] => "asjdk"
params[2] => "asdasndw"
complicated input should result to
params[0] => "asd"
params[1] => 'Y'
params[2] => "asd"
params[3] => 'X'
including the X and Y which are variables
how should i do the trick?
This should do the trick:
preg_match_all('/"([A-Za-z0-9]+)"/', '" "askdj" "asjdk" "asdasndw" "', $Matches))
You want to match a quote, then at least one alphanumeric character, then an ending quote. Put the alphanumeric characters in parentheses to capture the output and put it in $Matches
.
what is your variable $line value?
maybe you can var_dump($params) see its result, in regular expessions $params[o
preg_match_all("/\"([A-Za-z0-9\s]+)\"|([A-Za-z][A-Za-z0-9]*)/", '" "askdj" "asjdk" "asdasndw" "', $Matches))
因此,它将接受文字字符串和字符串变量。...@Zach Rattner的答案的大感谢。
