PHP修复了字符串变量中的零宽度空间

Question

I have zipcodes being outputted, coming from user inputted values. Looks like it is outputting zero-width-space \u200b sometimes at the beginning of the strings.

What is the best way to replace these from within php before echoing the variable?

Answer 1

I use this function to trim unicode spaces - this should work in your case too.

function trimUnicode($str) {
    return preg_replace('/^[\pZ\pC]+|[\pZ\pC]+$/u','',$str);
}
