php - 比较一个字符串和一个 php 数组，只显示匹配项

Question

我有一个看起来像这样的字符串:

"illustration,drawing,printing"

我有一个如下所示的数组:

Array (
    [0] => illustration
    [1] => drawing
    [2] => painting
    [3] => ceramics
)

如何比较两者并只显示同时存在于字符串和数组中的术语？

所以在上面的示例中，我想输出如下所示的内容:

SKILLS: illustration, drawing

谢谢!

Answer 1

使用explode() , array_intersect()和 implode()

<?php

$string = "illustration,drawing,printing";

$array = Array (
    0 => 'illustration',
    1 => 'drawing',
    2 => 'painting',
    3 => 'ceramics'
);

$stringArray = explode(',',$string);

$common = array_intersect($stringArray,$array);

echo "Skills :".implode(',',$common);
