Question

如果内容（文本）相同，我想比较两个字符串。

我有这两个字符串

字符串1-$ preset->消息

rebracket = {91: 123, 93: 125}
a = '[100:0.345,123:0.34,145:0.86]'
literal_eval(a.translate(rebracket))

字符串2-$ _data ['message']

Dear {contact_firstname} {contact_lastname}

Thank you for registering on the {companyname} CRM System.

We just wanted to say welcome.

所以我想以此方式比较它们

第一

Dear {contact_firstname} {contact_lastname}

Thank you for registering on the {companyname} CRM System.

We just wanted to say welcome.

对我来说，两个字符串都是相同的，但是上面的代码表示不同

所以我想获得更多信息

if ($_data['message']!=$preset->message){...}

结果我得到99.428571428571％

所以，如果文本已经相同或不同，我该如何以一种简单而又有效的方式进行检查？我的尝试似乎不是这样做的正确方法...

在此先感谢您的帮助。

Answer 1

您必须修剪空格，制表符和换行符才能比较这种冗长的字符串。尝试下面的代码。

$str1 = preg_replace("/\s+/", " ", $str1);
$str2 = preg_replace("/\s+/", " ", $str2);

if($str1 == $str2) {
    echo '1';
} else {
    echo '0';
}

Answer 2

$str1 = "Dear {contact_firstname} {contact_lastname}

Thank you for registering on the {companyname} CRM System.

We just wanted to say welcome.
