php 模板替换
如果 我要将模板文件的{$a}替换成 而不要把其他的{ok}这里面的替换 只替换有变量的 请问这样代码怎么实现? 把变量前面的替换我倒是知道 preg_replace('#{\s*\$#','
------解决方案--------------------

PHP code

$str='{$a}{ok}';
echo preg_replace('#\{(\$\w+)\}#','<?php echo $1;?>',$str); <div class="clear">
                 
              
              
        
            </div>
