What to do if php string segmentation fails ?

Solution to the problem that the explode() function cannot split the tab key in php

I encountered a problem a few days ago: it requires reading each character in the file One row, and split each column into an array, where each column is separated by the tab key ("\t").

It is natural to think of using fgets() to read each line in the file and split it using the explode() function.

$f=fopen("xxx","r"); $line=fgets($f); $line=explode("\t",$line);

I found that the expected effect was not obtained. The explode() function cannot split a string with the tab key as the separator.

Later I thought of a way, use str_replace() function to replace the tab key in the file, and then use explode() to split it.

$f=fopen("xxx","r"); $line=fgets($f); $line=str_replace("\t","_",$line); $line=explode("_",$line);
