Example $var  = “/var/xyz/html/uploaddata/xyz.html”;

“/”replace with “-” 

$str = str_replace(‘/’, ‘-‘,  $var);

result is -var-xyz-html-uploaddata-xyz.html

Example     $var  = “var-xyz-html-uploaddata-xyz.html”;

“-“replace with “/”

$str = str_replace(‘-‘, ‘/’,  $var);

result is /var/xyz/html/uploaddata/xyz.html

“/”replace with “\” 

Example $var  = “/var/xyz/html/uploaddata/xyz.html”;

$test = str_replace(‘/’, “\\”, $var );

result is \var\xyz\html\uploaddata\xyz.html
