Summary of Accounting Practice report PHP Digest generation function No garbled

In the use of the time, you have to generate a summary of the content strip_tags (), of course, you can also add strip_tags () directly into the function, I did not engage, add it myself. Here is the function:

Copy the Code code as follows:

function Cutstr ($string, $length, $charset, $dot) {//characters, intercept length, character set, end symbol
if (strlen ($string) <= $length) {
return $string;
}
$pre = Chr (1);
$end = Chr (1);
Protect Special strings
$string = str_replace (Array (' & ', ' ' ', ' < ', ' > '), Array ($pre. ') & '. $end, $pre. ' ". $end, $pre. ' < '. $end, $pre. ' > '. $end), $string);
$strcut = ";
if (Strtolower ($charset) = = ' Utf-8 ') {
$n = $tn = $noc = 0;
while ($n < strlen ($string)) {
$t = Ord ($string [$n]);
if ($t = = 9 | | $t = = 10 | | (<= $t && $t <= 126)) {
$tn = 1; $n + +; $noc + +;
} elseif (194 <= $t && $t <= 223) {
$tn = 2; $n + = 2; $noc + = 2;
} elseif (224 <= $t && $t <= 239) {
$tn = 3; $n + = 3; $noc + = 2;
} elseif (<= $t && $t <= 247) {
$tn = 4; $n + = 4; $noc + = 2;
} elseif (248 <= $t && $t <= 251) {
$tn = 5; $n + = 5; $noc + = 2;
} elseif ($t = = 252 | | $t = = 253) {
$tn = 6; $n + = 6; $noc + = 2;
} else {
$n + +;
}
if ($noc >= $length) {
Break
}
}
if ($noc > $length) {
$n-= $tn;
}
$strcut = substr ($string, 0, $n);
} else {
for ($i = 0; $i < $length; $i + +) {
$strcut. = Ord ($string [$i]) > 127? $string [$i]. $string [+ + $i]: $string [$i];
}
}
To restore a special string
$strcut = Str_replace (Array ($pre. ' & '. $end, $pre. ' ". $end, $pre. ' < '. $end, $pre. ' > '. $end), Array (' & ', ' "', ' < ', ' > '), $strcut);
Fixed an issue where special string segments occurred
$pos = Strrpos ($s, Chr (1));
if ($pos!== false) {
$strcut = substr ($s, 0, $pos);
}
return $strcut. $dot;
}

The above introduces the Accounting Practice report summary PHP Digest generation function No garbled, including the Accounting Practice report summary of the content, I hope that the PHP tutorial interested in a friend helpful.
