If format of 1 is specified, then the function will return an array containing all the words found inside the string. If format of 2 is specified, then the function will return an associated array where the position of the word is the key and the word itself is the value. For the purpose of this function, 'word' is defined as a locale dependent string containing alphabetic characters, which also may contain, but not start with "'" and "-" characters. // // version: 906.1814 // discuss at: http://phpjs.org/functions/str_word_count // + original by: Ole Vrijenhoek // + bugfixed by: Kevin van Zonneveld (http://kevin.vanzonneveld.net) // + bugfixed by: Brett Zamir (http://brett-zamir.me) // % note 1: Original author stated that "charlist parameter works correct but the last word in the given string will not be counted", but seems to work // * example 1: $P.str_word_count('Hello fri3nd, youre looking good today!', 1, 'àáãç3'); // * returns 1: ['Hello', 'fri3nd', 'youre', 'looking', 'good', 'today'] // A word is valid when it contains a-z A-Z ' - Ole Vrijenhoek var l = str.length, tmpStr = ""; var i = 0; var c = ''; var wArr = [], wC = 0; var assArr = {}, aC = 0, reg = ""; if (charlist) { for(i = 0; i<=charlist.length - 1; i++) { if (i != charlist.length - 1) { reg = reg + charlist.charCodeAt(i) + "|"; } else { reg = reg + charlist.charCodeAt(i); } } reg = new RegExp(reg); } for (i = 0; i <= l-1; i++) { c = str.charCodeAt(i); if ((c<91&&c>64)||(c<123&&c>96)||c == 45||c == 39||(reg && reg.test(c))) { if(tmpStr == "" && format == 2) { aC = i; } tmpStr = tmpStr + String.fromCharCode(c); } else if(tmpStr != "") { if (format != 2) { wArr[wArr.length] = tmpStr; } else { assArr[aC] = tmpStr; } tmpStr = ""; wC++; } } if (!format) { return wC; } else if (format == 1) { return wArr; } else if (format == 2) { return assArr; } throw 'You have supplied an incorrect format'; } , strcasecmp: function (f_string1, f_string2){ // Binary safe case-insensitive string comparison // // version: 810.1317 // discuss at: http://phpjs.org/functions/strcasecmp // + original by: Martijn Wieringa // + bugfixed by: Onno Marsman // * example 1: $P.strcasecmp('Hello', 'hello'); // * returns 1: 0 var string1 = (f_string1+'').toLowerCase(); var string2 = (f_string2+'').toLowerCase(); if(string1 > string2) { return 1; } else if(string1 == string2) { return 0; } return -1; } , strchr: function ( haystack, needle, bool ) { // An alias for strstr // // version: 905.1002 // discuss at: http://phpjs.org/functions/strchr // + original by: Philip Peterson // - depends on: strstr // * example 1: $P.strchr('Kevin van Zonneveld', 'van'); // * returns 1: 'van Zonneveld' // * example 2: $P.strchr('Kevin van Zonneveld', 'van', true); // * returns 2: 'Kevin ' return this.strstr( haystack, needle, bool ); } , strcmp: function ( str1, str2 ) { // Binary safe string comparison // // version: 812.316 // discuss at: http://phpjs.org/functions/strcmp // + original by: Waldo Malqui Silva // + input by: Steve Hilder // + improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net) // + revised by: gorthaur // * example 1: $P.strcmp( 'waldo', 'owald' ); // * returns 1: 1 // * example 2: $P.strcmp( 'owald', 'waldo' ); // * returns 2: -1 return ( ( str1 == str2 ) ? 0 : ( ( str1 > str2 ) ? 1 : -1 ) ); } , strcspn: function (str, mask, start, length) { // Finds length of initial segment consisting entirely of characters not found in mask.
