php如何从数组中提取出包含某一字符串的数组的值

array('aa' => '3,4,5,6;',
'bb' => '3,4,6,7;',
'cc' => '5,8,1,3;',
'dd' => '1,5,7,9;'
)

现在我想找出哪些值包含了字符'3,4' 并输出
请问要怎么写呢？

Answer 1

$map = array('aa' => '3,4,5,6;',
'bb' => '3,4,6,7;',
'cc' => '5,8,1,3;',
'dd' => '1,5,7,9;'
);
foreach ($map as $k =>$v) {
if (strpos($v, '3,4') !== false) {
echo "'$k' => '$v'<br />";
}
}
