[php-src] Issue #11139: BUG: PHP-Embed: php_embed_module.php_ini_path_override not properly processed.

Issue: https://github.com/php/php-src/issues/11139 Author: ronpinkas ### Description The following self contained, reduced, code: ``` #include <stdio.h> #include <sapi/embed/php_embed.h> void cb_php( int argc, char **argv, const char *eval_string, const char *cPathINI ){ char sIniPath[ 1024 ]; if( cPathINI && strlen(cPathINI) > 0 ){ strcpy( sIniPath, cPathINI ); php_embed_module.php_ini_path_override = sIniPath; printf( "INI: %s\n", php_embed_module.php_ini_path_override ); } else{ php_embed_module.php_ini_path_override = NULL; } PHP_EMBED_START_BLOCK(argc, argv); zend_eval_string((char *)eval_string, NULL, "embed_script"); PHP_EMBED_END_BLOCK(); } void CreateFile( char *FileName, char *Content ){ FILE *file = fopen( FileName, "w" ); if (file == NULL){ printf("Error: Unable to create '%s' file!\n", FileName ); exit( 1 ); } fprintf( file, "%s", Content ); fclose( file ); } int main(int argc, char *argv[]){ #define IniName "myphp.ini" #define ScriptName "check_settings.php" char *sPHP = "<?php\n" "// Check relevant PHP settings\n" "$settings = [\n" " 'max_input_time',\n" " 'obscure_setting'\n" // Add the obscure setting here "];\n" "echo \"PHP Settings:\\n\";\n" "foreach ($settings as $setting) {\n" " echo $setting . ': ' . ini_get($setting) . \"\\n\";\n" "}\n" "echo 'Loaded Configuration File: ' . php_ini_loaded_file() . \"\\n\";\n" "?>\n"; CreateFile( IniName, "max_input_time = 30\nobscure_setting = 12345\n" ); CreateFile( ScriptName, sPHP ); cb_php( argc, argv, "require( \"./" ScriptName "\" );", "./"IniName ); return 0; } ``` Resulted in this output: ``` INI: ./myphp.ini PHP Settings: max_input_time: 30 obscure_setting: 12345 Loaded Configuration File: /home/omie/dsv/omie-corevm/phpemb/myphp.ini ``` But I expected this output instead: ``` INI: ./myphp.ini PHP Settings: max_input_time: -1 obscure_setting: Loaded Configuration File: /home/omie/dsv/omie-corevm/phpemb/myphp.ini ``` ### PHP Version PHP 8.1.16 ### Operating System Amazon Linux 2
