一段$ string太长了......太长了...... php

Question

我在这里做错了什么？

 $string = "string How Long is a Piece of String?";

if $string = <5;
{
echo "string is less than 5";
}

else
{
echo "string is more than 5";
}

Answer 1

1,条件在括号中.

2,你不需要; 在一个条件之后.

3,小于<not <=除非你想要回应"字符串少于或等于5"

$string = "string How Long is a Piece of String?";

if (strlen($string) < 5)
{
   echo "string is less than 5";
}
else
{
   echo "string is more than 5";
}
