explode and implode in php

The function of explode is to use one string to split another string. Returns a split array.

Let’s look at the basic usage of explode:

<br>

<br>The program output is:

Array<br>(<br> [0] => <br> [1] => aa<br> [2] => bb<br> [3] = > <br>)<br>

You can see that the first and last x of the string str are interpreted as spaces, and the middle x splits the string in half. If there are multiple x's in the middle, the extra x's will be interpreted as spaces.

If str is set to xaaxxxbbx

, the output of the program is:

Array<br>(<br> [0] => <br> [1] => aa<br> [2] => <br> [4] => bb<br> [5] => <br>)<br><br>

explode also has an optional parameter limit.

The function of limplode is to convert a one-dimensional array into a string. Let’s look at its basic usage:

 'aa',
    'b' => 'bb',
    'c' => 'cc'
);
$str  = implode('x', $data);
echo $str;
?>

The program output is: aaxbbxcc

The first parameter is the connector, if it is a space, The output is aa bb cc. If the first parameter is not filled in, the output is aabbcc
