PHP explode() 将字符串打散为数组
实例1
<?php
$str = "Hello world. I love Shanghai!";
print_r (explode(" ",$str));
?>
例子 1
使用 limit 参数来返回一些数组元素：
PHP implode() 将数组变成字符串
$str = 'one,two,three,four';
// 零 limit
print_r(explode(',',$str,0));
// 正的 limit
print_r(explode(',',$str,2));
// 负的 limit
print_r(explode(',',$str,-1));
?>
<?php
$array = array('lastname', 'email', 'phone');$comma_separated = implode(",", $array);echo $comma_separated; // lastname,email,phone// Empty string when using an empty array:var_dump(implode('hello', array())); // string(0) ""
