心事如莲,心静如水。驾一叶轻舟,吹一支长笛,自池塘深处,揽一朵莲花入怀,似红粉佳人,晶莹剔透,亭亭玉立,娇俏动人,喜一分,爱一分,怜一分,朵朵幽香入心田,丝丝柔情潜心底。
本文实例讲述了php自定义函数实现JS的escape的方法。分享给大家供大家参考,具体如下:
//php function function escape($string) { $n = $bn = $tn = 0; $output = ''; $special = "-_.+@/*0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"; while($n < strlen($string)) { $ascii = ord($string[$n]); if($ascii == 9 || $ascii == 10 || (32 <= $ascii && $ascii <= 126)) { $tn = 1;$n++; } elseif(194 <= $ascii && $ascii <= 223) { $tn = 2;$n += 2; } elseif(224 <= $ascii && $ascii <= 239) { $tn = 3;$n += 3; } elseif(240 <= $ascii && $ascii <= 247) { $tn = 4;$n += 4; } elseif(248 <= $ascii && $ascii <= 251) { $tn = 5;$n += 5; } elseif($ascii == 252 || $ascii == 253) { $tn = 6;$n += 6; } else { $n++; } $singleStr = substr($string,$bn,$tn); $charVal = bin2hex(iconv('utf-8', 'ucs-2', $singleStr)); if(base_convert($charVal, 16, 10) > 0xff) { if (!preg_match("/win/i", PHP_OS)) $charVal = substr($charVal, 2, 2).substr($charVal, 0, 2); $output .= '%u' . $charVal; } else { if(false !== strpos($special, $singleStr)) $output .= $singleStr; else $output .="%" . dechex(ord($string[$bn])); } $bn = $n; } return $output; }
希望本文所述对大家PHP程序设计有所帮助。
