[php-src] Issue #15003: Comparing string to integer without casting or intval gives unexpected behavior since version 7.4

Issue: https://github.com/php/php-src/issues/15003 Author: AwkAmr ### Description The following code: This was tested in multiple environments, including docker container. ```php <?php $testStrings = ["Abdelfatah", "hello", "123abc", "abc123", "", "0"]; foreach ($testStrings as $testString) { echo "Testing with string: " . var_export($testString, true) . "\n"; echo "Integer conversion: " . var_export((int)$testString, true) . "\n"; echo "Is string > 90: " . var_export($testString > 90, true) . "\n"; echo "Is string == 0: " . var_export($testString == 0, true) . "\n"; echo "Is (int)string > 90: " . var_export(((int)$testString) > 90, true) . "\n"; echo "intval(string) > 90: " . var_export(intval($testString) > 90, true) . "\n"; echo "is_numeric(string): " . var_export(is_numeric($testString), true) . "\n"; echo "\n"; } ``` Resulted in this output: (From latest version 8.3.9) ```Testing with string: 'Abdelfatah' Integer conversion: 0 Is string > 90: true Is string == 0: false Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: 'hello' Integer conversion: 0 Is string > 90: true Is string == 0: false Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: '123abc' Integer conversion: 123 Is string > 90: false Is string == 0: false Is (int)string > 90: true intval(string) > 90: true is_numeric(string): false Testing with string: 'abc123' Integer conversion: 0 Is string > 90: true Is string == 0: false Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: '' Integer conversion: 0 Is string > 90: false Is string == 0: false Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: '0' Integer conversion: 0 Is string > 90: false Is string == 0: true Is (int)string > 90: false intval(string) > 90: false is_numeric(string): true ``` But I expected this output instead: (Output gotten from version 7.4.33) ```Testing with string: 'Abdelfatah' Integer conversion: 0 Is string > 90: false Is string == 0: true Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: 'hello' Integer conversion: 0 Is string > 90: false Is string == 0: true Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: '123abc' Integer conversion: 123 Is string > 90: true Is string == 0: false Is (int)string > 90: true intval(string) > 90: true is_numeric(string): false Testing with string: 'abc123' Integer conversion: 0 Is string > 90: false Is string == 0: true Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: '' Integer conversion: 0 Is string > 90: false Is string == 0: true Is (int)string > 90: false intval(string) > 90: false is_numeric(string): false Testing with string: '0' Integer conversion: 0 Is string > 90: false Is string == 0: true Is (int)string > 90: false intval(string) > 90: false is_numeric(string): true ``` ### PHP Version 8.3.9 ### Operating System _No response_
