PHP to extract specific words - php

Question

I have a string like the below in a variable called $CPU. The text is below, my target is to pull specific element of the below text.
[{
"#attributes": {
"name": "processors"
},
"entry": ["2", "1", "successful"],
"entries": {
"#attributes": {
"name": "processor"
},
"entry": ["Intel(R) Core(TM) i5-7200U CPU # 2.50GHz", "GenuineIntel", "2500000000", "3100000000", "2", "4", "true", "9", "100 MHz", "7"],
"entries": {
"#attributes": {
"name": "caches"
},
"entries": [{
"#attributes": {
"name": "cache"
},
"entry": ["Level 1 Cache", "131072"]
}, {
"#attributes": {
"name": "cache"
},
"entry": ["Level 2 Cache", "524288"]
}, {
"#attributes": {
"name": "cache"
},
"entry": ["Level 3 Cache", "3145728"]
}]
}
}
}]
The thing I want to extract specifically is this bit is the "Intel(R) Core(TM) i5-7200U CPU # 2.50GHz" however I'm really unsure how to achieve this easily.

It's a JSON! So if it works for JS it will work for PHP:
$arr = json_decode($CPU, true);
echo $arr[0]["entries"]["entry"][0];
var x = [{
"#attributes": {
"name": "processors"
},
"entry": ["2", "1", "successful"],
"entries": {
"#attributes": {
"name": "processor"
},
"entry": ["Intel(R) Core(TM) i5-7200U CPU # 2.50GHz", "GenuineIntel", "2500000000", "3100000000", "2", "4", "true", "9", "100 MHz", "7"],
"entries": {
"#attributes": {
"name": "caches"
},
"entries": [{
"#attributes": {
"name": "cache"
},
"entry": ["Level 1 Cache", "131072"]
}, {
"#attributes": {
"name": "cache"
},
"entry": ["Level 2 Cache", "524288"]
}, {
"#attributes": {
"name": "cache"
},
"entry": ["Level 3 Cache", "3145728"]
}]
}
}
}]
console.log(x[0]["entries"]["entry"][0])
