This article brings you a code example about PHP converting a relative path to an absolute path through realpath. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
Relative path-> Absolute path:
relative path $c_abs = realpath($ss_rel); if ($c_abs === false) { $i_rtn = -1; } else { $ss_rel = $c_abs; $i_rtn = 0; } $lpc++; } // while (count($sv_path)>0) // normal ending if (0===$i_rtn) { $out_abs = $ss_rel; // set converted path } return $i_rtn; } // test $inDir = "/Users/Mch/Code/php/Directory"; is_dir($inDir) || mkdir($inDir, 0777, true); $wd = __DIR__; chdir($inDir); $out = ""; echo sub_rel2abs("../../../eclipse-workspace/blog.zip", $out).PHP_EOL; echo $out.PHP_EOL; chdir($wd); @rmdir($inDir); ?>
output:
0 /Users/Mch/eclipse-workspace/blog.zip
Just realpath here, why bother?
