定期爲一個字符串序列化數據

Question

我在新的WordPress插件的工作，但我需要一個定期expresison幫助，所以請如果你能幫助，我有這個

a:6:{s:5:"width";s:4:"3000";s:6:"height";s:4:"2100";s:14:"hwstring_small";s:23:"height=\'89\' width=\'128\'";s:4:"file";s:25:"2012/02/sopa_nicearma.jpg";s:5:"sizes";a:3:{s:9:"thumbnail";a:3:{s:4:"file";s:23:"sopa_nicearma-15x10.jpg";s:5:"width";s:2:"15";s:6:"height";s:2:"10";}s:6:"medium";a:3:{s:4:"file";s:25:"sopa_nicearma-300x210.jpg";s:5:"width";s:3:"300";s:6:"height";s:3:"210";}s:5:"large";a:3:{s:4:"file";s:25:"sopa_nicearma-700x490.jpg";s:5:"width";s:3:"700";s:6:"height";s:3:"490";} 
}s:10:"image_meta";a:10:{s:8:"aperture";s:1:"0";s:6:"credit";s:0:"";s:6:"camera";s:0:"";s:7:"caption";s:0:"";s:17:"created_timestamp";s:1:"0";s:9:"copyright";s:0:"";s:12:"focal_length";s:1:"0";s:3:"iso";s:1:"0";s:13:"shutter_speed";s:1:"0";s:5:"title";s:0:"";}} 

，但我想刪除這個表達式

s:9:"thumbnail";a:3:{s:4:"file";s:23:"sopa_nicearma-15x10.jpg";s:5:"width";s:2:"15";s:6:"height";s:2:"10";} 

，並最終有這個

'a:6:{s:5:"width";s:4:"3000";s:6:"height";s:4:"2100";s:14:"hwstring_small";s:23:"height=\'89\' width=\'128\'";s:4:"file";s:25:"2012/02/sopa_nicearma.jpg";s:5:"sizes";a:3:{s:6:"medium";a:3:{s:4:"file";s:25:"sopa_nicearma-300x210.jpg";s:5:"width";s:3:"300";s:6:"height";s:3:"210";}s:5:"large";a:3:{s:4:"file";s:25:"sopa_nicearma-700x490.jpg";s:5:"width";s:3:"700";s:6:"height";s:3:"490";} 
}s:10:"image_meta";a:10:{s:8:"aperture";s:1:"0";s:6:"credit";s:0:"";s:6:"camera";s:0:"";s:7:"caption";s:0:"";s:17:"created_timestamp";s:1:"0";s:9:"copyright";s:0:"";s:12:"focal_length";s:1:"0";s:3:"iso";s:1:"0";s:13:"shutter_speed";s:1:"0";s:5:"title";s:0:"";}} 

所以，在我要刪除的結束，這種中刪除

鏈{鏈 「的名字像」 鏈}

我有這樣的想法

$var=preg_replace("(.+)\{(.+)(sopa_nicearma\-15x10\.jpg)(.+)\}/", "", $var); 

但不做工精細becouse我有這個

}s:10:"image_meta";a:10:{s:8:"aperture";s:1:"0";s:6:"credit";s:0:"";s:6:"camera";s:0:"";s:7:"caption";s:0:"";s:17:"created_timestamp";s:1:"0";s:9:"copyright";s:0:"";s:12:"focal_length";s:1:"0";s:3:"iso";s:1:"0";s:13:"shutter_speed";s:1:"0";s:5:"title";s:0:"";}} 

Answer 1

你不應該這樣做與正則表達式。這些是序列化的對象，如果您手動編輯其中任何可以更改任何包含字符串長度的任何內容，則還必須更改長度參數。

相反，您應該通過執行$data = unserialize($data);進行非串行化數據更改，然後再使用$data = serialize($data);對其進行連續化。
