How to diff file's apostrophe text in PHP - php

Question

I want to diff 2 files and ignore checking lines that doesn't have apostrophe ("text") in PHP
For example:
File 1:
START
LTEXT "Tool Version:", IDC_STATIC, 70, 150, 80, 10, SS_RIGHT
EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT
File 2:
/*

/
START
LTEXT "Wersja narzędzia:", IDC_STATIC, 70, 150, 80, 10, SS_RIGHT
EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT
I want to check if there's any difference between Tool Version: and Wersja narzędzia: strings.
Note: Files doesn't have this same schemas line by line - I want to start diff lines from line that have START in file.

Answer 1

You should first get content of each file and then use preg_match function with proper pattern to find version line and version string.
$fileContent1 = <<<TXT
dummy
dummy
LTEXT "Tool Version:", IDC_STATIC, 70, 150, 80, 10, SS_RIGHT EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT
dummy
TXT;
$fileContent2 = <<<TXT
dummy
LTEXT "Wersja narzędzia:", IDC_STATIC, 70, 150, 80, 10, SS_RIGHT EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT
dummy
dummy
TXT;
function diff_versions($leftContent, $rightContent) {
$diff = true;
$leftVersion = null;
$rightVersion = null;
$pattern = '/LTEXT "(Tool Version|Wersja narzędzia):", (.*)\R?/';
if (preg_match($pattern, $leftContent, $matches) !== 1) {
throw new Exception('Left content has no version line.');
}
$leftVersion = $matches[2];
if (preg_match($pattern, $rightContent, $matches) !== 1) {
throw new Exception('Right content has no version line.');
}
$rightVersion = $matches[2];
return array(
'diff' => $leftVersion === $rightVersion,
'leftVersion' => $leftVersion,
'rightVersion' => $rightVersion,
);
}
var_dump(diff_versions($fileContent1, $fileContent2));
Output:
array (size=3)
'diff' => boolean true
'leftVersion' => string 'IDC_STATIC, 70, 150, 80, 10, SS_RIGHT EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT' (length=89)
'rightVersion' => string 'IDC_STATIC, 70, 150, 80, 10, SS_RIGHT EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT' (length=89)
And then you should diff versions as you like.

Maybe this will give a point to start with:
$str1 = 'LTEXT "Tool Version:", IDC_STATIC, 70, 150, 80, 10, SS_RIGHT
EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT';
$str2 = 'LTEXT "Wersja narzędzia:", IDC_STATIC, 70, 150, 80, 10, SS_RIGHT
EDITTEXT IDC_STATIC_TIME, 155, 50, 210, 10, ES_LEFT';
$shortStr1 = substr($str1, 23);
$shortStr2 = substr($str2, 28);
echo "\n";
echo substr_compare($shortStr1, $shortStr2, 0, strlen($shortStr1));
echo "\n";
echo substr_compare($shortStr2, $shortStr1, 0, strlen($shortStr2));
Two compares if the Strings are not the same size
Will return 0 if same
Will return 1 if not same
For a better test you have to test via preg_match() and pre_match_all()
I think this - or at least the idea - will lead you to the answer.
