php数组与字符串之间的转换

我们在实际使用PHP进行字符串和数组之间进行转换时，implode和explode两个函数将会比较有用。implode() 函数进行PHP数组转字符串，explode() 函数则是用来实现PHP字符串转数组的。

一、PHP数组转字符串 implode()

<?php
$vegetables[0] = "corn";
$vegetables[1] = "broccoli";
$vegetables[2] = "zucchini";
$text = implode(",", $vegetables);
echo $text;
?>

运行结果为：corn,broccoli,zucchini

二、PHP字符串转数组 explode()

<?php
$text = "corn, broccoli, zucchini";
$vegetables = explode(", ", $text);
print_r($vegetables);
?>
其运行结果为：
Array
(
[0] => corn
[1] => broccoli
[2] => zucchini
)
