Replace strings in PHP files with shell script

Question

Good morning to everyone here, attempt to replace a series of characters in different PHP files taking into account the following:

The files are lines like this:

if($_GET['x']){

And so I want to replace:

if(isset($_GET['x'])){

But we must take into account that there are files in lines like the following, but they do not want to modify the

if($_GET["x"] == $_GET["x"]){

I try as follows but I can not because I change all lines containing $ _GET ["x"]

My example:

find . -name "*.php" -type f -exec ./code.sh {} \;

sed -i 's/\ if($_GET['x']){/ if(isset($_GET['x'])){/' "$1"

find . -name "*.php" -type f -print0 | xargs -0 sed -i -e "s|if *(\$_GET\['x'\]) *{|if(isset(\$_GET['x'])){|g" --

The pattern above for if($_GET['x']){ would never match if($_GET["x"] == $_GET["x"]){.

Update:

This would change if($_GET['x']){ or if($_GET["x"]){ to if(isset($_GET['x'])){:

find . -name "*.php" -type f -print0 | xargs -0 sed -i -e "s|if *(\$_GET\[[\"']x[\"']\]) *{|if(isset(\$_GET['x'])){|g" --

Another update:

find . -name "*.php" -type f -print0 | xargs -0 sed -i -e "s|if *(\$_GET\[[\"']\([^\"']\+\)[\"']\]) *{|if(isset(\$_GET['\1'])){|g" --

Would change anything in the form of if($_GET['<something>']){ or if($_GET["<something>"]){.

Thank you very much for your quick response, but this code still did not make any change :(

What's the output of sed --version? Any other error message you see?

sed (GNU sed) 4.2.2, not replace me $ _GET ['x'] for isset ($ _GET ['x']) ignoring lines that are like this $ _GET ['x'] == $ _GET ['x']

Mine is actually just 4.2.1. What do you get if you do echo "if(\$_GET['x']){" | sed -e "s|if *(\$_GET\['x'\]) *{|if(isset(\$_GET['x'])){|g"?

if(isset($_GET['x'])){ if(isset($_GET['x'])){
