[英]Search and replace words in a string with regular expression
我有一個像這樣的字符串:
"This is a random string with @[certain] words with this format @[something]"
我想替換由@[]
包裹的單詞
所以我的結果必須是這樣的:
"This is a random string with words with the format"
我正在使用PHP。
您可以為模式使用正則表達式,並使用preg_replace
替換字符串。
像這樣
$str = "This is a random string with @[certain] words with this format @[something]";
$newStr = preg_replace('/\ @\[(\w+)\]/','',$str);
您也可以將其寫成一行,
echo preg_replace('/\ @\[(\w+)\]/','',"This is a random string with @[certain] words with this format @[something]");
