Replace variable texts with regular expressions - php

Question

I'm reformulating one of my old programs and using TextCrawler to automate text replacements in several code files, but I'm struggling to make the following change:
I need to find all 'text' functions (example):
$object->text('TRANSLATE_KEY_A')
$object->text('TRANSLATE_KEY_B')
...
and replace them with (example):
__('RETURNED_TEXT_FROM_TRANSLATE_KEY_A', TEXT_DOMAIN)
__('RETURNED_TEXT_FROM_TRANSLATE_KEY_B', TEXT_DOMAIN)
...
Where RETURNED_TEXT_FROM_TRANSLATE_KEY_X are set with the 'text' array's key in another code file
array_push($text, array('key' => 'TRANSLATE_KEY_A',
'extras' => '',
'text' => 'Translated Text A'));
array_push($text, array('key' => 'TRANSLATE_KEY_B',
'extras' => '',
'text' => 'Translated Text B'));
The final result should be:
$object->text('TRANSLATE_KEY_A')
$object->text('TRANSLATE_KEY_B')
...
replaced with
__('Translated Text A', TEXT_DOMAIN)
__('Translated Text B', TEXT_DOMAIN)
...
There are over 1500 of these :(
Is it possible to achieve this with regular expression in TextCrawler, and how? Or any other idea? Thanks

If you want to use a php array to provide the replacement data it is probably best to just use php itself for the task.
Example script.php:
// your $text array
$text = array();
array_push($text, array(
'key' => 'TRANSLATE_KEY_A',
'extras' => '',
'text' => 'Translated Text A')
);
array_push($text, array(
'key' => 'TRANSLATE_KEY_B',
'extras' => '',
'text' => 'Translated Text B')
);
...
// create a separate array from your $text array for easy lookup
$data_arr = array();
foreach ($text as $val) {
$data_arr[$val['key']] = $val['text'];
}
// your code file, passed as first argument
$your_code_file = $argv[1];
// open file for reading
$fh = fopen($your_code_file, "r");
if ($fh) {
while (($line = fgets($fh)) !== false) {
// check if $line has a 'text' function and if the key is in $data_arr
// if so, replace $line with the __(...) pattern
if (preg_match('/^\$object->text\(\'([^\']+)\'\)$/', $line, $matches)
&& isset($data_arr[$matches[1]])) {
printf("__('%s', TEXT_DOMAIN)\n", $data_arr[$1]);
} else {
print($line);
}
}
fclose($fh);
} else {
print("error while opening file\n");
}
Call:
php script.php your_code_file
Just add functionality to iterate over all of your code files and write to the corresponding output files.
