PHP读取ini文件并修改内容写入

读取ini文件并改写数据写入到ini

updateTime.ini
 
#更新时间记录
[fileUpdateTime]
time = ""
[sqlOtherUpdateTime]
time = "2022-06-08"
[sqlUpdateTime]
time = "2022-05-15"

方法一

function write_ini_file($array, $file) {
    $res = array();
    foreach($array as $key => $val) {
        if(is_array($val)) {
            $res[] = "[$key]";
            foreach($val as $skey => $sval) {
                $res[] = "$skey = ".(is_numeric($sval) ? $sval : '"'.$sval.'"');
            }
        } else {
            $res[] = "$key = ".(is_numeric($val) ? $val : '"'.$val.'"');
        }
    }
    safefilerewrite($file, implode("\r\n", $res));
}
 
function safefilerewrite($fileName, $dataToSave) {
    if ($fp = fopen($fileName, 'w')) {
        $startTime = microtime(TRUE);
        do {
            $canWrite = flock($fp, LOCK_EX);
            if(!$canWrite) usleep(round(rand(0, 100)*1000));
            
        } while ((!$canWrite)and((microtime(TRUE)-$startTime) < 5));
        
        if ($canWrite) {
            fwrite($fp, $dataToSave);
            flock($fp, LOCK_UN);
        }
        fclose($fp);
    }
}
 
$timeInfo = parse_ini_file('updateTime.ini',true);
$timeInfo['sqlOtherUpdateTime']['time'] = date("Y-m-d", time());
 
write_ini_file($timeInfo, "updateTime.ini");

方法二

function write_ini_file_tow($assoc_arr, $path, $has_sections=FALSE) {
    $content = "";
    if ($has_sections) {
        foreach ($assoc_arr as $key=>$elem) {

                if(is_array($elem2))
                {
                    for($i=0;$i<count($elem2);$i++)
                    {
                        $content .= $key2."[] = \"".$elem2[$i]."\"\n";
                    }
                }
                else if($elem2=="") $content .= $key2." = \n";
                else $content .= $key2." = \"".$elem2."\"\n";
            }
        }
    }
    else {
        foreach ($assoc_arr as $key=>$elem) {
            if(is_array($elem))
            {

                    $content .= $key."[] = \"".$elem[$i]."\"\n";
                }
            }
            else if($elem=="") $content .= $key." = \n";
            else $content .= $key." = \"".$elem."\"\n";
        }
    }
    
    if (!$handle = fopen($path, 'w')) {
        return false;
    }
    
    $success = fwrite($handle, $content);
    fclose($handle);
    
    return $success;
}
 
$timeInfo = parse_ini_file('updateTime.ini',true);
$timeInfo['sqlOtherUpdateTime']['time'] = date("Y-m-d", time());
 
write_ini_file_tow($timeInfo, 'updateTime.ini', true);
