PHP deletes the character between the two specified characters in a string
To do the problem in the project, you need to delete the character between the two specified characters in the string.

Substr ($str,$i2,strlen ($str)); echo $str. "
". $str1;// line-breaking output, contrast result / / output result / / 1meme2018-04-15mm 20purl 15purl 11meme 2meme2018-04-15Eng 20purl 15purl 11meme 3meme2018-04-15Ensemble 20purl 15purl 11meme 4meme2018-04-15Ensemble 20purl 1511 / 1prime2018-04-15century 20purl 1511 / OK, perfect. } simply encapsulate it (it feels troublesome after encapsulation) But write it down, public function getStr ($str,$str1,$n1,$str2 (N2) {/ * $str is the string to be processed * $str1 is the only selected string * $N1 is intercepted from the first string in $str * $str2 is the selected unique string * $N2 is the end of the string in $str2 * / $i1=strpos ($str,$str1) + $N1 $i2=strpos ($str,$str2,$i1) + $N2; $str1=substr ($str,0,$i1-1). Substr ($str,$i2,strlen ($str)); return $str1;} take a chestnut and use the encapsulation method to make the following five values as follows: $str= "1 str1=", 2, "2"; $N1 = "2"; / / intercept $str2= ","; $N2 = "1" from 2 of the specified values; / / intercept to the first of the specified values, that is, echo (getStr ($str,$str1,$n1,$str2,$n2)); / / well, the result is the same, it's not easy, ha, above is all the content of the article "how to delete strings between specified characters by php", thank you for reading!
