$arr = array(
"a" => "1"
"b" => "2"
"c" => "3"
"d" => "4"
"e" => "5"
"f" => "6"
);
$str = array(
"xxxxx{a}xxxxx{b}xxxx{f}xxxx",
"xxxxx{b}xxxxx{c}xxxx{d}xxxx",
"xxxxx{a}xxxxx{d}xxxx{e}xxxx",
);
the way I came up with is
foreach($str as $v)
{
foreach($arr as $ke=>$va)
{
$v = str_replace("{".$ke."}", $va, $v);
}
$newStr[] = $v;
}
return $newStr;
it doesn"t feel good to go through all the $arr every time.
can you guys give me some advice?

str_replace
array_walk($str, function(&$v, $k) use ($arr){
$v = strtr($v, $arr);
});if you don't want to loop, you can try this:
$arr = array(
'{a}' => '1',
'{b}' => "2",
'{c}' => "3",
'{d}' => "4",
'{e}' => "5",
'{f}' => "6",
);
$str = array(
'xxxxx{a}xxxxx{b}xxxx{f}xxxx',
'xxxxx{b}xxxxx{c}xxxx{d}xxxx',
'xxxxx{a}xxxxx{d}xxxx{e}xxxx',
);
$newStr = implode('|||', $str);
$newStr = strtr($newStr, $arr);
$newStr = explode('|||', $newStr);
print_r($newStr);another tips: pure string using single quotation marks is a little bit faster than double quotation marks
I don't know if this is the result you want.
$result = array_map(function($item) use ($arr) {
return str_replace(array_keys($arr), array_values($arr), $item);
