A common method of intercepting string interception string by JS

1:explode Split string

eg

$str = XXX:ABC;

$ABC = Explode (': ', ' $str '); Obtained is an array of

echo $ABC [1]; Output ABC

Cons: Must know the split point, and the location of the required data

Advantages: Good understanding

2:str_replace replacing string Parts

eg

$str = ABCDEFG;

$ABC = Str_replace (' DEFG ', ' ', ' $str '); Replace the DEFG with empty

Echo $abc; Output ABC

Disadvantage: The replaced part must be known

Advantages: Good understanding

3:SUBSTR Calendar String

eg

$str = ABCDEFG;

$re = Array ();

for ($i = 0; $i < strlen ($STR); $i + +) {//convert $str to an array

$re [] = substr ($str, $i, 1);

}

echo $re [0]. $re [1]. $re [2]; Output ABC

Cons: Must know the entire string, inefficient

Advantages: Random Splicing
