arrays - PHP preg_split both slashes -


i have string this: "c:\users\jamie/desktop/test.txt"

i want use preg_split split string array this, using code:

$arr = preg_split("/(\\|\/)/", "c:\users\jamie/desktop/test.txt");

what expect is:

array(0=>"c:",1=>"users",2=>"jamie",3=>"desktop",4=>"test.txt")

but got is

array(0=>"c:\users\jamie/desktop/test.txt")

how can expected result using preg_split?

simple:

$parts = preg_split('~[\\\\/]~', $filename);

the ~ delimiters. regular expressions can use pretty delimiter. so, instead of /.../ can ~...~.

when working backslashes have double-escape them, \\\\. regular expression engine come out \\. in other words, both backslashes in \\ need escaped, hence \\\\.

you can use following, if prefer.

$parts = preg_split('/[\\\\\/]/', $filename);

edit. little confusing. maybe explain in way:

  • in php \\\\ seen 2 escaped backslashes, i.e. \\.
  • to regex engine \\ seen 1 escaped backslash, i.e. \.
