php - Globally Replace Old School $PHP_SELF with $SERVER['PHP_SELF'] using sed
Get the solution ↓↓↓
Not being an sed expert, I need to replace all instances of the string$PHP_SELF with$_SERVER['PHP_SELF'] globally in a directory.
This is an "old school" osCommerce application that I need to resurrect temporarily for a showcase.
Answer
Solution:
sed doesn't recurse on it's own so you'll need to use another tool for that,find is generally the right answer.
Run this in the top-level directory.sed will make a backup of each file it reads with a.bak extension (regardless if it actually does a replacement). If you don't want the backup behavior, use-i instead of-i.bak
I recommend you first try this on a test directory to make sure it meets expectations.
#!/bin/bash
while IFS= read -r -d $'\0' file; do
sed -i.bak $'s/$PHP_SELF/$_SERVER[\'PHP_SELF\']/g' "$file"
done < <(find . -type f -name "*.php" -print0)
