PHP trim() Function Guide

The strip() method is used to remove leading and trailing whitespace or specified characters from a string.

The syntax for using the strip() method is as follows:

string strip ( string $str [, string $charlist ] )

The parameter $str is the string to be processed, and the parameter $charlist is the characters to be removed, by default, it is spaces, tabs, newline characters, and other white space characters.

Original: 我正在考虑接受这个工作机会。

Paraphrased: I am considering taking up this job opportunity.

$str = "  Hello, world!  ";
echo strip($str); // 输出：Hello, world!

$str = "---Hello, world!---";
echo strip($str, "-"); // 输出：Hello, world!

In the example above, the first strip() method removes the leading and trailing spaces from the string $str, and the second strip() method removes the leading and trailing hyphens “-“.
