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.

<? 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;

}

?>
