Php truncates a string between two characters

Php truncates a string between two characters

In php, you only need to determine a stripos location before string 1 and string 2, and then use substr to start the truncation. Here is a simple example.

Usage:

1 2	$ Keyword = 'search (group experiment )' $ Need = getNeedBetween ($ keyword ,'(',')');

After running the program:

1	$ Need = 'group lab ';

The following describes how to use the string truncation function getNeedBetween. This function allows you to extract strings between two specified characters ($ mark1, $ mark2) from the string ($ kw). If the string fails, 0 is returned, and the string is successfully returned.

1 2 3 4 5 6 7 8 9 10 11 12

<? Php Function getNeedBetween ($ kw1, $ mark1, $ mark2 ){ $ Kw = $ kw1; $ Kw = '000000'. $ kw. '000000 ′; $ St = stripos ($ kw, $ mark1 ); $ Ed = stripos ($ kw, $ mark2 ); If ($ st = false | $ ed = false) | $ st >=$ ed) Return 0; $ Kw = substr ($ kw, ($ st + 1), ($ ed-$ ST-1 )); Return $ kw; } ?>
