PHP Regex使用preg_replace切断空间

Question

I have some string like this

Name xxx Product 1 Pc 100
Name Pci Product2Pc.200
Name Pcx Product 3 Pcs300

I want to turn PC to Price And this is result that I want

Name xxx Product 1 Price 100
Name Pci Product 2 Price 200
Name Pcx Product 3 Price 300

At first I use

$pattern = array('/(\s*)Product(\s*)/', '/(\s*)(Pc\.?|Pcs)(\s*)/');

But it came to change all of my PC to Price

Name xxx Product 1 Price 100
Name Price i Product 2 Price 200
Name Price x Product 3 Price 300

This is my code now.

$pattern = array('/(\s*)Product(\s*)/', '/[^a-z](Pc\.?|Pcs)[^a-z]/');
$replacement = array(' Product ', ' Price ');
$title = preg_replace($pattern, $replacement, $title, -1);

But it result like this

Name xxx Product 1 Price 100
Name Pci Product Price 00
Name Pcx Product 3 Price 00

Thanks you.

Answer 1

Regex:

(Product)\s*(\d+)\s*Pc[.s]?\s*(\d+)

Replacement string:

$1 $2 Price $3

DEMO

$string = <<<EOT
Name xxx Product 1 Pc 100
Name Pci Product2Pc.200
Name Pcx Product 3 Pcs300
EOT;
$pattern = "~(Product)\s*(\d+)\s*Pc[.s]?\s*(\d+)~";
echo preg_replace($pattern, "$1 $2 Price $3", $string);

Output:

Name xxx Product 1 Price 100
Name Pci Product 2 Price 200
Name Pcx Product 3 Price 300
